CAVALRY

At the beginning of the First World War, horsed cavalry was still an army’s principal mobile arm. However, after the onset of static trench warfare on the Western Front in late 1914 – with thick barbed wire barriers and large numbers of machine guns protecting defensive works – the battlefield utility of cavalry was greatly diminished. Cavalry was nonetheless retained in large numbers because of the perennial hope of breaking through the enemy’s line and rolling up his defences from the rear. Thus, for virtually every major offensive operation during the war, cavalry divisions were kept in reserve.

Canada contributed two distinct groups of cavalry during the War – the Canadian Cavalry Brigade and an independent cavalry regiment known as the Canadian Light Horse.

Canadian Cavalry Brigade

This Canadian Cavalry Brigade was formed in England in the autumn of 1915, consisting of permanent force units, the Royal Canadian Dragoons and Lord Strathcona’s Horse, along with the Royal Canadian Horse Artillery. In early 1916, The Fort Garry Horse, a militia regiment from Winnipeg, was added, along with a Cavalry Brigade Machine Gun Squadron equipped with Vickers machine guns. The Canadian Cavalry Brigade served as part of a British cavalry division for the remainder of the war. Its first mounted action was at the Somme in the summer of 1916. When cavalry units were not needed as reserves for an offensive operation, they were often employed dismounted to occupy quiet sectors of the front.

The Brigade again saw mounted action in March 1917 when tasked to pursue an unexpected German withdrawal to a new defensive position called the Hindenburg Line. During this pursuit, Lieutenant Harvey of Lord Strathcona’s Horse earned the brigade’s first Victoria Cross for valour during the liberation of a French village. By the time of the Battle of Cambrai in November 1917 – best known as the first major tank offensive of the war – the Canadian cavalry was judged to be among the best brigades in the British Cavalry Corps, and it was tasked to serve in the lead of a large cavalry exploitation force. During this operation, a single Canadian squadron was the only cavalry to penetrate German lines, and Lieutenant Strachan of The Fort Garry Horse was awarded the Victoria Cross for gallantry.

The Brigade served with great distinction during the German’s March 1918 offensive toward Amiens, riding from place to place assisting in slowing the relentless enemy advance. Its final action in this operation took place at Moreuil Wood, where Lieutenant Flowerdew of Lord Strathcona’s Horse won a posthumous Victoria Cross for leading a gallant cavalry charge against German machine guns. After the war, Marshal Foch, the Allied supreme commander, credited the Canadians with halting the German offensive at Moreuil and preventing the separation of the French and British armies. Later in that final year of the war, the Canadian Cavalry Brigade was in action during the great Canadian Corps victory over the Germans at Amiens in August, and it played an important part in following up the German retreat in the last two months of the war.

Canadian Light Horse

Until May 1916, three of the four infantry divisions of the Canadian Corps maintained their own independent cavalry squadron of some 150 all ranks . These squadrons – from the 19th Alberta Dragoons, the 1st Hussars and the 16th Light Horse – were then amalgamated into an ad hoc regiment that reported directly to Canadian Corps Headquarters. In early 1917, this unit was named the Canadian Light Horse.

The Canadian Light Horse first saw action as a mounted unit in the consolidation of the ground captured in the attack on Vimy Ridge in April 1917. The CLH played a major role in the fighting at Iwuy on October 10, 1918, where the last ever swords-drawn charge by Canadian cavalry took place. During the pursuit of the Germans in the final month of the war, CLH squadrons were always well out in front as a scouting force, ensuring that the Canadian divisions would not be surprised by German lay-back patrols. When the war ended for the Canadians in Mons Belgium on November 11, 1918, the Canadian Light Horse was already well beyond the city.

TANKS

Modern armoured fighting vehicles – tanks and armoured cars – owe their development in part to the stalemate created on the Western Front by the deadly combination of machine guns and thick belts of barbed wire protecting trench lines, along with massive artillery bombardments that could be brought down with great accuracy on an attacking force. The problem of how an attacking force could be strengthened to overcome well-defended trenches had been studied by British scientists since late 1914. They came up with the idea of a ‘land ship’ – a tracked vehicle protected by armour plate, large enough that it could carry guns or machine guns, drive over belts of barbed wire, and crossover trenches. This highly secret vehicle was given the code name ‘tank’.

Tanks were first introduced in limited numbers during the battle of the Somme in mid-September 1916, and the Canadian Corps was given seven (these models were called the Mark I) for its attack on the village of Courcellette. But these early versions were mechanical nightmares; almost all broke down before they got anywhere close to the German lines. Still, scientists kept improving their tank designs. Finally, in November 1917, tanks were used in large numbers in a successful offensive at Cambrai: the era of mechanized warfare had been born. Tanks then played major roles in the Battle of Amiens in August 1918, in the breaking of the Hindenburg Line in September, and in the pursuit of the retreating Germans in October and November 1918.

Early in 1918 many thought the war might well last into 1919, and the Canadian Army agreed to raise tank units. The 1st Canadian Tank Battalion was recruited from university students, and in June 1918 it was sent to England to begin training at the British Tank School. Despite the general aversion to volunteering at this stage in the war, a 2nd Battalion was also quickly raised. The 1st Tank Battalion had just completed its training and was preparing to leave for the front when the Armistice was declared on November 11, 1918. Thus, while no Canadian tank unit saw action in the war, many Canadians did serve in British tank battalions, and in a number of instances displayed their nationalism by painting maple leafs prominently on their vehicles.

THE MOTOR MACHINE GUN BRIGADE

In 1914, Canada created the world’s first armoured unit. The driving force behind this achievement was Raymond Brutinel, a wealthy engineer originally from France, who had the idea that lightly armoured vehicles designed to carry machine guns would be especially useful. He offered to raise the funds for the vehicles, a suggestion which was readily accepted by the government. Brutinel designed the vehicles, had them built, purchased the machine guns, and recruited the soldiers, all within two months. His new unit was given the name ‘Automobile Machine Gun Brigade No. 1’. In the next few months three other mobile machine gun units were raised, all paid for by private subscription – the Eaton Battery, the Borden Battery and the Yukon Battery. All four units found their way to France where, in 1915, they were amalgamated under Brutinel’s command as the Canadian Motor Machine Gun Brigade.

Brutinel’s Motors came into their own in the last year of the war, when the stalemate of trench warfare had been broken. This highly mobile force played an especially important role in stemming the onslaught of the Germans’ March 1918 offensive, and a second similar brigade was formed. The Motors were a valuable part of a composite formation of cavalry, armoured cars and cyclists, termed ‘The Independent Force’, during the Battle of Amiens in August 1918. Between September and November this force led the Canadian Corps from one victory to another during the pursuit to Valenciennes and finally to Mons on November 11, when the war ended.

THE CYCLISTS

At the beginning of the war, each Canadian division had its own company of cyclists – troops equipped with sturdy bicycles whose tasks included field security and aspects of military intelligence. In the static conditions on the Western Front, they were not very useful, so they tended to be used as guards or labourers. In May 1916 the four companies were amalgamated as The Canadian Corps Cyclist Battalion. In 1918, the battalion was included in Brigadier-General Brutinel’s ‘Independent Force’, and there they served valiantly at Amiens and in the Pursuit to Mons as a form of mounted infantry – riding to the scene of action, dismounting and then fighting as infantry.

The emotions of capture are etched in the faces of new prisoners of war. There is fear – my life is now in the hands of an enemy who may or may not let me live. There is the kind of bewilderment that exists only in the mind of someone just emerging from the fog of war. There is relief – at last, I’m out of the shooting war. There is guilt – should I have done more to prevent being captured? On top of it all, there is exhaustion.

The emotion of fear probably came first since the moment of capture was the most dangerous time for a prisoner. It was a reality of the First World War that the protection given to prisoners under the 1907 Hague Convention was not always observed in the front lines. Throwing aside one’s rifle and yelling “Kamarad” was no guarantee that the plea for mercy would be heeded, particularly if the approaching soldier had seen his unit decimated by enemy fire. By the same token, a platoon that was weakened by casualties and struggling to hold a hard-won position sometimes could not spare a couple of infantrymen to escort prisoners to the rear areas. In such cases, soldiers implicitly understood that the safest option for their unit was to shoot the prisoners and keep it to themselves.

And then there were the rumours that circulated through both sides of no man’s land about a particular battalion that never took prisoners, or about captives who were killed rather than being sent to the safety of a prison camp. A soldier who had been fired up by such stories might well wave aside his enemy’s pleas and pull the trigger instead. The faces you see in these films, then, represent the lucky ones, the soldiers who actually survived to become prisoners.

We should also be aware that there did exist a degree of sympathy between soldiers. Atrocities were committed on both sides, but often the sight of a cowering enemy soldier elicited a feeling of pity in the attacking soldier. This is not the demonic Hun depicted by the propagandists, he might think; this is a man like me, with a family, perhaps a wife and children. We are both caught in a war that is not our doing; I will treat him as I hope he would treat me, with kindness and consideration.

The exhausted Canadian sharing coffee and hardtack with a captured German became a stock propaganda image, as a way to demonstrate the kindness of our Canadian boys overseas. But just because they were propagandized does not mean such situations did not take place. On the contrary, many a soldier would share with his prisoner a water bottle, a packet of rations or a cigarette, because the fact that he was a fellow soldier was now more important than the fact that he was an enemy. There is genuine good humour in the image of the captor clowning with the captive by putting on his cap and pulling a face.

Once the new prisoner made it through the moment of capture and reached relative safety, his experiences in captivity became more typical. The First World War was a very labour-intensive conflict. It was the first truly mechanized war, but much of the heavy work was still done the old-fashioned way – by tens of thousands of men digging, carrying, lifting and moving. Neither side had any scruples about using prisoners as forced labour in or directly behind the front lines. We know that German units used their POWs to dig trenches, move ammunition and carry supplies – all tasks forbidden under international law – and Canadians may well have done the same. But such scenes would never have made it onto film. Instead, a much more common image is of German soldiers acting as stretcher bearers, bringing the wounded, Canadian and German alike, to safety. For the captors, this had the advantage of freeing up infantrymen who had been temporarily co-opted as stretcher bearers – every German prisoner who could carry a stretcher meant that one Canadian could go back to the firing line. But it also had value for the prisoners themselves. Many contemporary accounts tell of new prisoners who were almost pathetically keen to prove themselves useful by helping with the wounded. Carrying a stretcher, after all, was much better than being shot.

Prisoners were also a valuable source of information. They were searched for maps, papers or anything else that could have intelligence value (or even monetary value – Canadian soldiers were known as tireless souvenir hunters, and quickly stripped any item that could be sold to non-combatant troops in the rear areas. Rifles, canteens and other military equipment were confiscated and sent to salvage dumps. Then, German-speaking officers questioned the men about their unit and the defences on their side of the line. Probably, few POWs were as helpful as some of those who were filmed (including the one who is evidently hard of hearing, likely from artillery bombardment), but the evidence suggests that prisoners were actually forthcoming with information about what was going on in their own trenches.

Finally, the symbolic significance of prisoners should not be underestimated. It was important to depict German prisoners on film because they were very visible signs of success on the battlefield. In the bloodbaths of 1916 and 1917, when success was measured in yards of pulverized earth, scenes of a few bedraggled German soldiers proved that something concrete had been achieved. The Battle of the Somme, for example, was a notorious example of horrific casualties sustained for very little territorial gain, but footage of prisoners being marched away from the battlefield in this clip at least proved that there were a few enemy infantrymen who would never again fire on Canadian soldiers.

In the open campaigns that began in the summer of 1918, prisoners became even more dramatic evidence of success. Now, it was possible to show to Canadians images of long lines of Germans soldiers captured in battle as the Canadian Expeditionary Force swept across northern France. Scenes of POWs being marched away from the battle for Bourlon Wood in 1918, often combined with pictures of rows of captured artillery pieces, confirmed to people at home that the tide had finally turned. The Allies had the Germans on the run, and such images seemed to prove that they were just as happy to surrender as fight.

Statistics on German POWs captured by Canadian troops are far from complete. We know that over 4000 were captured at Vimy Ridge in April 1917; over 5000 on August 8, 1918, the first day of the Battle of Amiens; and roughly 6000 in the three-day battle for the Drocourt-Quéant line in September 1918. But these are only three of dozens of engagements fought by the Canadian divisions, and the total number of prisoners taken may never be known. In any case, the cold statistics tell us less about the experience of captivity than these moving images. The men we see remain nameless, but their faces speak volumes about the impact of war on the individual.

Battlefield medicine in the First World War faced two related challenges: removing soldiers from the battlefield and then providing the necessary treatment to save life and limb. In fact, a medical practitioner’s first duty was to determine whether a sick or wounded soldier needed to be moved further back into the system or whether he (if a nursing sister, she) could be returned to productive good health while remaining on duty. The process was called triage and was conducted at each stage of the chain of evacuation.

Triage

On the battlefield, stretcher bearers, who were selected from the infantry or detached from a Field Ambulance unit, determined if the soldier needed to be treated, required immediate evacuation, or a combination of the two. The same process was repeated at the Regimental Aid Post (which was part of an infantry battalion at the front), at the Advanced Dressing Station (a section of a Field Ambulance), the Main Dressing Station (another section of the Field Ambulance), the Casualty Clearing Station, and the various forms of hospital near the front or well behind it, in England or even Canada.

The need for triage was not limited to times when the Canadian Corps was fighting battles—far from it—for disease had caused more casualties than combat since time immemorial. Even after such developments as vaccination in the 18th century and the studies of germs in the 19th, the sick were still plentiful among Canadian soldiers. Many conditions still forced tens of thousands to seek treatment. Among them were influenza, with some 65,000 ill in 1918-19; gonorrhea with over 45,000 ill in the course of the war; tonsillitis and sore throat with about 20,000 ill; syphilis with approximately 18,000; trench fever (caused by a bacterium transmitted by fleas), though non fatal, struck 18,000; myalgia (muscle pain) made some 15,000 sick, as did intestinal disease.

The Canadian Expeditionary Force (CEF), however, was free of the kinds of epidemic diseases that had caused such ravages in the Crimea, the Spanish-American War and South Africa.

Influenza

Near the end of the conflict the medical corps did find itself in the midst of one of the great pandemics of human history, the influenza scourge of 1918–19. Killing millions, it can be compared to the plague of Justinian in the 6th century or the Black Death in the 14th. Though 30–50,000 Canadians would succumb to the disease, the great majority were on the home front and not members of the expeditionary force. According to official history, 3825 of those who went overseas died of disease, 776 of influenza.

The CEF still had a problem on its hands, as the illness “flooded the rest station and camps with sick” in the summer of 1918, and “The ailment was peculiar in that, while exhibiting the symptoms of influenza, it ran its course in a week or eight days. It spread rapidly and necessitated the promulgation of extensive and stringent precautionary orders to prevent its spread. All public places such as Unit Entertainments, YMCA Cinema Shows, Estaminets [small French cafés serving alcohol] &c were closed for a time. In the latter places it was permitted to serve drinks at tables outside the buildings.”¹

Treating Wounds

Such illness was in addition to the medical challenges posed by the weapons of war and by the very ground being fought over. The conflict on the Western Front took place mainly on farmland that had been well-fertilized with manure, and its accompanying bacteria, for decades or centuries. The result, according to Canada's official medical historian of the conflict, was that nearly all wounds were infected. Sulpha drugs would not become available until the 1930s, and antibiotics would have to await another world war before coming into use, so infection was a serious challenge that could only be met by irrigating wounds with available chemicals and convalescence that could last months.

Another danger of wounds on the battlefield was shock due to blood loss, which could be fatal. The simple solution, first attempted in 1916, was to replace the patient’s blood with blood drawn from a donor; chemical preservatives and refrigeration allowed for the life-giving fluid to be stored for a period of time, and such blood was being transfused by the end of 1917. One practitioner was Norman Guiou, who recalled in April 1918:

We had our first opportunity to do several transfusions. The dressing station was set up in a Nissen hut, the stretchers were supported on trestles. There were a number of seriously wounded... One lad was brought in on a blood-soaked stretcher, with a shattered humerus - his upper arm swathed in copious blood-soaked dressings. A flicker of pulse was present. He was pale, "starey-eyed", and tossed about and pulled his wound tag off... We bled a donor about 750cc while the chaplain talked to him. If there is a dramatic procedure in medicine it is the blood transfusion. Color came into that lad's cheeks. He raised himself on his good elbow, drank tea, and ate some YMCA fancy biscuits, then was on to the casualty clearing station.²

Psychological Injuries

One final challenge is worthy of mention here, that of psychological injury. According to medical historian Tom Brown, the condition was “the storm centre of military medicine” at that time. Symptoms could include uncontrollable weeping, trembling, paralysis, deafness and other manifestations without known physical causes. At first it was called shell shock, as it was thought that it resulted from the shock wave of an exploding shell damaging the brain, but by the middle part of the war the condition was thought to be purely psychological in nature. The patient could be diagnosed as suffering from hysteria or neurasthenia and could receive shock
treatment, talk therapy or simple rest in a hospital out of earshot of artillery. Most of the Canadian soldiers who suffered from such injuries were sent to No 3 Canadian Stationary Hospital in France, which specialized in such care.

Hospitals serve as examples of just how complex the treatment of sick and wounded soldiers had become by the First World War. Institutions specialized in ear and eye conditions, rheumatism, psychological injury, tuberculosis, orthopaedics, and venereal disease, in addition to general, stationary and convalescent hospitals. In an industrialized war, hospitals could become battlefield targets. Many nursing sisters and patients were killed when a hospital was bombed in 1918. They were among the 504 medical practitioners killed on the battlefield serving with Canadian units; another 127 succumbed to disease.

The conflict that raged in different parts of the world from 1914 to 1918 was a total war: entire populations and economies were mobilized, and millions of people were killed on the battlefield or died of disease and famine. It has also been called an industrialized war, where the management techniques of large manufacturers were applied to the task of killing one’s enemies. Engineers, therefore, played a prominent role and in such a wide variety of enterprises that simply providing a list would take several pages, so only those that employed large numbers of troops will be described here.

Forestry

The Western Front made huge demands in matériel, lumber being an excellent example. Wood was needed to revet trenches, support the roofs of dugouts, for plank or corduroy roads, and as sleepers for tramways and railways. These tasks became the responsibility of the military engineers, specialized forestry units being formed for the purpose. Lumberjacks, graders and other skilled men from within the lumber industry were recruited. They cut timber and ran their own sawmills to provide a finished product.

The first forestry companies in the war were formed in 1915, in France. More units were created in England to harvest the island’s local resources. All of these were gathered into a corps in 1916 that eventually comprised 43 companies, and was of such a scale as to require its own hospital system. The men received more than the normal food rations, considering the fact that they were engaged in continuous hard labour.

Their work, in Britain and France, saved huge amounts in shipping costs, not to mention freeing up lumber supplies for such industrial endeavours as shoring up mines and building trawlers and other vessels. Nor did the forestry corps limit its work to cutting and preparing wood. Many of its units supported the Royal Air Force by clearing, draining, levelling and grading sites for aerodromes. By the time of the Armistice 11,750 men worked within its ranks, with another 6000 attached in various capacities.

Railways

Closer to the fighting there was a need for heavy-capacity means of transport to get the prodigious amounts of ammunition, food, water and other necessary matériel to the front line. One solution to such an intimidating logistical problem was the construction of tramways with specialized labour, with other specialists maintaining and operating the tractors and rolling stock. The result was a system of transport similar to that of a large North American city run by the Canadian Railway Troops. The troops worked on the Western Front and also in Palestine, the 1st Bridging Company serving there in the last part of the war. The system was, in fact, a merging of two networks, tramways closer to the front operating with gasoline-powered tractors while light railways a little farther behind used steam power, the whole being linked to France’s broad gauge system, which had been built in the decades before the conflict.

In the end, the war became too mobile for railway troops to keep up, and when an Armistice was declared on November 11, 1918, the railways were some 30 kilometres behind the forward troops, in spite of the work of 25,000 railway construction engineers, two-thirds of them Canadian. Still, they had served their purpose in the almost four years of near-static warfare that characterized the Western Front from late 1914 to the summer of 1918.

Tunnelling

It became clear in the early months of the First World War that operations above ground were distinctly hazardous, even suicidal, hence the trenches and dugouts in which soldiers took shelter. An obvious course was to begin operating underground, and within the Canadian Corps three specialized tunnelling companies were formed. Recruited in the main among miners and clay-kickers (the latter dug smaller tunnels to run gas and water mains under city streets), they began their work in 1915, and their role was multi-faceted. First, they used the galleries they excavated under enemy lines to listen in on his own work, the aim being to give fair warning if he began to threaten Canadian lines underground. Second, they might pack the galleries with explosives to destroy enemy defences; generally, however, such operations proved disappointing as German forces usually occupied the crater thus created before Canadian or British troops could reach it.

Tunnelling was particularly hazardous. Working underground can release toxic gas capable of disabling or killing, or one could find oneself tunnelling into an enemy gallery, leading to vicious little skirmishes fought with knives and digging tools. When fighting shifted from a mutual siege to more open warfare in 1918, tunnellers applied their skills to other work, disarming booby traps in dugouts and other underground facilities as the Allies advanced towards the German border. In fact, the only Canadian military engineer ever to be awarded the Victoria Cross was Captain C.N. Mitchell, a tunneller who in 1918 removed explosives from a bridge while under attack.

Field Engineering

The most versatile of the engineers operated on the front line. Originally organized in field companies of a hundred men or so, in 1918 they were reorganized into larger battalions and even brigades. Regardless of how they were administered, their tasks were widely varied. Just behind the front line they were responsible for building and maintaining roads, as well as providing water for humans and animals, the latter task requiring some of them at least to possess knowledge of how to locate and test the precious liquid. To give just two examples, part of the preparations for the assault on Vimy Ridge included laying over 40 miles (65 km) of four-inch (10 cm) pipe, with five pumping stations and a total storage capacity of 560,000 gallons. Following the successful advance at Amiens in August 1918, one of the deepest penetrations achieved on the Western Front, the Canadian Corps and its allies found itself in the midst of a plain scorched dry by the summer sun, but engineers needed only two days to locate sufficient water to keep forward troops satiated.

In the front lines proper, sappers, as they were called, dug trenches, or oversaw this work done by the infantry work parties, and prepared defensive positions with the copious use of barbed wire. On occasion, as for a trench raid, for example, they were called upon to destroy such wire, using long cylinders filled with explosive called ammonal tubes or bangalore torpedoes. When that front line advanced, as in 1918, bridging became a most crucial sapper task, as forward movement could not be maintained without ammunition, water, food, and the other necessities of making war, all of which needed to be transported forward on roads or railways, both of which needed bridges to get across rivers and other, similar obstacles. Small structures made of cork sufficed to get the infantry across, while prefabricated materials called Inglis bridges carried heavier loads.

At the time of the Armistice what could be called field engineers (as opposed to railway and forestry troops) could count 14,285 men within their ranks, with responsibilities only somewhat less diverse than their numbers.

The Great War has often been called the gunner’s war. “The artillery conquers and the infantry occupies,” remarked one French general. That was too simplistic, of course, as infantry tactics developed throughout the war, but the artillery barrage was the key to victory or defeat.

In 1914 and 1915, artillery proved it was the great killer. For those caught in the open, shrapnel and high explosive shells wreacked havoc. Thousands were left rotting on the battlefields. However, artillery guns were vulnerable to small arms fire, and they could be driven away from the front. But the guns were soon firing indirectly from hidden positions several kilometeres to the rear, still causing terrible damage. Soldiers were forced to find safety in trenches, digging beneath the ground to escape the murderous fire.

As trenches were strengthened with barbed wire, deep dugouts, and machine -guns, an enormous weight of fire was needed to smash the enemy defences and support the infantry. But there were not always enough shells in the early years to feed the guns. And so the infantry were killed in the tens of thousands as they attacked undamaged enemy trenches in frontal assaults. As the war lengthened, artillerymen received nearly unlimited supplies of shells through the enormous production of munitions factories. New tactics were also developed to improve the accuracy of the guns.

Artillery shells contained high explosives, shrapnel, and, later in the war, poison gas and smoke. Both the high explosive and shrapnel shells were timed to detonate in the air above a target. High explosive shells blasted holes in the trenches and the concussion alone could kill, as lungs collapsed under the force of the explosion. Shrapnel shells were equally deadly, consisting of more than 300 rounded metal balls that exploded downward in a cone-shaped rain of whirling metal. As well, the casing of the shell was designed to explode outward, creating jagged, uneven shards of steel that tore through flesh.

By 1916, commanders believed that massive artillery shoots, involving hundreds of thousands of shells, would annihilate the enemy defenders. This would allow the infantry to punch a hole through enemy lines and restore mobility on the Western Front.

However, it was often hard to hit, and then destroy, the narrow and well-fortified trenches. The problem also lay in the shell fuses. Earlier types were not sensitive enough to explode on contact, especially with shells tasked to clear barbed wire. As a result, many of the shells exploded in the ground, killing very few of the enemy, leaving the infantry to fight their way through defences-in-depth. By the end of 1916, newer, sensitive fuses that exploded on the slightest contact harnessed the destructive power of the artillery and, equally important to the infantry, cleared barbed wire from in front of enemy trenches.

Tactics again changed during the later phases of the bloody battles of the Somme in the last half of 1916. The gunners would never be able to destroy all of the German defences, and even one machine -gunner could kill hundreds of attacking infantry. Instead, the artillery sought to suppress enemy fire through a “creeping barrage,” and give their own attacking infantry enough time to cross the killing zone of nNo Mman’s Lland.

Gunners fired their shells to create a “creeping” wall of fire that slowly moved forward over the enemy lines at fixed intervals: 50 yards (46 m) every couple of minutes, less for muddy ground, more for open warfare. In effect, it was a screen of fire and explosives. As this moving wall of shrapnel and high explosives chewed up the ground in its path, the infantry were told to “lean into the barrage” and stay as close as possible. Although friendly fire was expected and occurred, the casualties would still be lighter than if the creeping barrage moved off and allowed German machine -gunners, waiting in the safety of deep dugouts, to get to the top of their trenches before the infantry crossed nNo Mman’s lLand.

At the Battle of Vimy Ridge in April 1917, the gunners had perfected the creeping barrage. Yet enemy gunners still took a fearful toll as they laid down their own counter-barrages to catch the follow-on waves of infantry. The enemy guns had to be stopped, or slowed, but it was exceedingly difficult to identify, target, and destroy camouflaged guns several kilometeres away.

Accurate intelligence was essential, and new and refined forms of science aided the gunners. The Canadian Corps was lucky to have Brigadier-General Andrew McNaughton, commander of the counter-battery office for much of the war, who embraced new technology and tactics. A prewar professor at McGill University, he turned to science to save his soldiers lives.

The Canadian Counter Battery Office (CCBO), established in February 1917, gathered intelligence and processed information on the enemy to assist in knocking out his guns. Aerial reconnaissance from the Royal Flying Corps (later Royal Air Force) was of great assistance as airmen photographed the front from great heights. Later in the war, observation aircraft circled the battlefield, passing real-time information to the gunners through letter drops and primitive wireless radio.

As the CCBO developed after April 1917, this information-gathering and target-selection became more sophisticated, with new technology, like sound-ranging and flash-spotting, assisting gunners to find and destroy enemy targets.

Flash-spotting involved the coordination of observers. At least three posts were needed, usually spread out along several kilometeres. When an enemy gun position was spotted by the revealing flash as the shell left the barrel, the observers were telephoned by headquarters to turn their attention to that spot. After studying the flash of the gun, the observers would hit a key that was connected to a lamp at headquarters. From the observers’ bearings, and by triangulating their estimates, enemy guns could be located with high precision.

Sound-ranging worked on a similar principle. Listeners sat two kilometeres behind the line with their microphones. Additional posts were manned well ahead of these positions. As long as there was not more than one shell per second being fired, on hearing the crash of an enemy gun, the forward listening post pressed a key that started an oscillograph, an instrument that recorded on film the sound of the shell in flight as it reached each microphone in turn. The time-intervals between the microphones allowed the CCBO to analyse the information and, if conditions were optimal, pinpoint enemy guns to within twenty-five 25 yards (23 m). All available counter-battery guns would be aimed on that spot to deliver a destructive shoot of 50-100 shells. Chemical shells were also used to kill or force the enemy gunners to wear debilitating respirators that severely affected the rate of fire.

In the last year of the war, artillery had perfected the creeping barrage and was steadily improving its counter-battery work. Further tactical refinement allowed gunners to fire more complicated barrages, like a box barrage. The box barrages set up a wall of fire and explosives around an enemy position —-- usually a trench —-- which effectively isolated it from reinforcements. It allowed assaulting Canadian infantrymen to capture and consolidate a position without fear of immediate counterattack.

By war’s end, 43,914 gunners had served in the Canadian artillery, and 2,565 had lost their lives from disease, injury, and battlefield wounds. They had fired tens of millions of shells, reducing the landscape to a desolate wasteland, and an estimated 60% of all wounds were inflicted by shell fire. The First World War was indeed a gunner’s war.

Between 10 January and 22 February 1917 the British Fifth Army, in a series of minor but
none the less hard-fought engagements preparatory to larger operations, pushed the
enemy five miles up the Ancre valley on a four-mile front; and on the night of 22-23
February the Germans fell back three more miles across a front of fifteen miles. The
inability of his forces to withstand British pressure in their present positions strengthened Crown Prince Rupprecht's argument for a general retirement to the Hindenburg Line at an early date. On 30 January Ludendorff agreed, not only because the consequent shortening of the front would release thirteen divisions and many artillery units for the projected offensive in Italy, but also because a general retirement could be expected to upset French and British campaign plans. It was in the German interest to delay as long as possible any struggle on the Western Front, in order to allow time for results from the campaign of unrestricted warfare by submarine and cruiser which had begun on 1 February. The deciding factor, however, appears to have been the need for time to replenish supplies of guns and shells, deliveries of which had fallen far short of von Hindenburg's orders and expectations.

On 4 February the High Command issued an order over the Kaiser's signature for a
withdrawal of the Seventh Army's right wing, the Second and First Armies, and the left wing of the Sixth Army to the Hindenburg Line between 15 and 18 March. This operation was aptly code-named "Alberich", after the malicious dwarf of the Nibelungen saga,28 for it called for the devastation of the whole area to be abandoned - nearly 100 miles of front between Soissons and Arras, averaging almost 20 miles in depth. Under this "scorched earth" policy all military installations and useful war material were removed from the existing forward zone, townspeople and villagers were evacuated and their communities razed, livestock were carried away or destroyed, and all wells were either filled in or polluted. To delay an Allied advance the retreating Germans felled trees across the roads, blew large craters at main intersections, and everywhere beset the pursuers' path with ingeniously laid booby-traps. Well organized rearguards covered the German withdrawal, though these received orders not to counter- attack. The skill of the Germans in concealing their plans from the Allies and the success of their delaying tactics helped prevent any effective follow-up. By the morning of 19 March, 29 divisions had completed the withdrawal with a minimum of Allied interference.29 Four Allied armies found themselves out of contact - from north to south, the right wing of the British Third Army about Arras, the Fifth and Fourth Armies to across the Somme valley, and the left wing of the French between Roye and the Aisne. It took until 5 April to drive in the German outposts and establish a new Allied line in front of the Hindenburg Position.*

The enemy's retirement did not greatly affect the plan of Nivelle's main offensive,
which was to be made east of Soissons. But it seriously upset the preliminary offensive in the north, for the Germans in the salient which converging British and French thrusts were to have pinched out had now escaped containment. Time was lacking in which to build new communications across the devastated area, particularly on the French left, where the retreat had been farthest. Accordingly, the northern attack became an all-British operation, the principal aim of which was to outflank the Hindenburg Line from the north and advance towards Cambrai. General Nivelle was forcibly told by Painlevé and Pétain and other high French officers that his scheme was no longer practicable. Army group commanders opposed the plan as a reversion to the discredited pre-war and 1914 overemphasis on offensive action for its own sake. There were also strategic and political objections. Neither the Russians nor the Italians would be able to mount offensives in time to render assistance; and the prospect of America's early entry into the war seemed another good reason for postponing a major French offensive. At one point Nivelle offered his resignation; but this being refused, he continued with his preparations. After various delays the assault on the Aisne was ordered to open on 16 April, the British offensive a week earlier.

* Taking part in the Fourth Army's advance was the Canadian Cavalry Brigade. On 27 March, Lieut. F.M.W. Harvey, Lord Strathcona's Horse, ran into a wired trench and captured a machine-gun, for which daring act he was awarded the V.C.

The night of September 26-27 1918 was tense with expectation. There was no preliminary barrage and the air was still. In the crowded assembly areas infantry were closely bunched with artillery and machine-guns, brought forward this far in readiness for a rapid advance. Apprehensive that a counter preparation by German artillery might come down on their dangerously dense numbers, the troops waited impatiently for zero. Rain began to fall and the cold ground became slippery, adding to the difficulties expected in the coming assault. Morning arrived overcast and dark, but the rain had stopped. Then, at 5:20 a.m., came a myriad of flashes from the guns in the artillery areas followed by the crash of bursting shells over the enemy positions.

On the Corps right, troops of the 10th Brigade, hugging their artillery cover, quickly crossed the canal on a two-battalion front between Inchy and Moeuvres. They overcame resistance from the Canal du Nord Line, and established them selves on Red according to schedule. The 11th and 12th Brigades, leading the 4th Division's attack on the right and left respectively, pushed forward but almost immediately met trouble from the south. Opposing General Watson's formations was the German 187th Infantry Division, with its 188th Infantry Regiment directly west of Bourlon Wood, flanked to north and south respectively by the 186th and 187th Regiments. Farther south was the dismounted 7th Cavalry Division; unused to infantry tactics they were quickly defeated. The 52nd Division, attacking on the Third Army's flank, had not achieved the same initial success as the 4th Division, and as a result the Canadian right suffered many casualties from enfilade fire.

In stiff fighting the 87th Battalion gained an entry into the southern part of Bourlon village by 9:45 a.m., and the 54th, passing through, skirted the north end of Bourlon Wood to reach the far side. The slower advance of the British troops to the south compelled the 102nd Battalion to form a defensive flank beside the Bapaume road and defeated the plan to encircle the wood from the south. This left the 54th in a pronounced salient, suffering mounting casualties. The battalion pushed on towards Fontaine-Notre-Dame, finally coming to a halt about 7:00 p.m. just west of the village, the 75th and 87th Battalions coming up on its left. Farther north the 12th Brigade also had stiff fighting throughout the day. The 85th and 38th Battalions, heavily hit by shelling and machine-gun fire during their advance, cleared their part of the Marquion trench system, allowing the 78th and 72nd Battalions to gain all but the extreme right of its Blue Line objective. It took a fresh attack mounted at 8:00 p.m. by the 78th Battalion to overcome the final pocket of resistance.

In the course of the 4th Division's operations on September 27 two subalterns had won the Victoria Cross. Lieutenant G.T. Lyall of the 102nd Battalion, and Lieutenant S.L. Honey, D.C.M., M.M., 78th Battalion, through their skilful leadership and courage in dealing with German strong points both significantly contributed to the capture of Bourlon Wood. Like many another recognition for brave deeds in the war, Lieutenant Honey's award came posthumously.

On the Corps left the 1st Division's success paid tribute to careful planning and well-directed and determined execution. Two guns of the 1st Battery C.F.A. gave the 1st Brigade a good start by moving in front of Inchy-en-Artois and firing point-blank into enemy positions along the canal. Thus aided, the 4th Battalion, having crossed the dry bed with little difficulty, was able to jump ahead to the north-east and capture its assigned portion of the Marquion Line. Here the 1st Battalion pushed through as planned and secured the Green Line in short order. The 2nd and 3rd Battalions now assumed the lead, only to be stopped by heavy fire from the embanked railway which curved north from Bourlon. With the aid of a timely flanking attack by the 72nd Battalion they overcame this resistance and swept on to the Blue Line. The action of the Commander of the 3rd Battalion's left support company, Lieutenant G.F. Kerr, M.C., M.M., in rushing single-handed a German strongpoint near the Arras-Cambrai road played an important part in the 1st Brigade's advance. Kerr, who captured four machine guns and 31 prisoners, was awarded the Victoria Cross.

The 2nd Brigade's role was to follow the 1st up to the Marquion Line and then extend to the left to capture the central portion of the Blue Line on the divisional front. By two o'clock the 7th Battalion was firm on its objective midway between Marquion and Haynecourt. During the afternoon the 5th Battalion went on to occupy Haynecourt and push patrols almost to the main Cambrai-Douai road. On the left, units of the 11th British Division passed through, headed for Epinoy. By the end of the day (September 27) patrols of the 10th Battalion-which had passed through the 5th just east of Haynecourtwere approaching the Marcoing Line, coming first to a heavy belt of uncut wire covered by enemy machine-guns. With mounting casualties the infantry cut the wire and pushed forward; but confronted by a second wire barrier, which marked the line itself, and with darkness approaching, the battalion consolidated on the east side of the Douai-Cambrai road.

On General Macdonell's left the 3rd Brigade had the important task of driving northward beyond the Canal du Nord and capturing in turn the villages of Sainslez-Marquion and Marquion, thereby freeing the eastern bank to permit crossings by the 11th Division. Leading the 3rd Brigade's advance the 14th Battalion crossed south of Sains-lez-Marquion, and swinging north behind the village, quickly captured its part of the Red Line. Four supporting tanks rendered good service in crushing wire barricades and in mopping up the village, but mechanical difficulties kept them from advancing past the Red Line. From Chapel Corner, south-east of Marquion, the German opposition, which had wavered before the initial rush of the 14th, rallied with heavy fire to stop the 13th Battalion, which was following up the initial assault. It took a joint effort by the 13th and 15th Battalions with tank assistance to clear Marquion. The 15th continued northward across the Arras road, mopping up the area east of the canal. By 2:00 p.m. it was firm at the Blue Line, just south of Sauchy-Lestrée.

Both Canadian divisions had received useful help from the tanks-each being supported by a company (of eight tanks) from the 7th Tank Battalion. The four allotted to each assaulting brigade successfully crossed the dry canal under cover of an artillery smoke-screen. Later they contributed to their own concealment by means of smoke dischargers fitted to their exhausts. During the day they gave good service in crushing wire entanglements and silencing with their fire enemy machine-gun posts. Of the sixteen tanks engaged in the first phase of the operation five fell victim to German fire.

About midday, when the 3rd Infantry Brigade had completed its assigned task of clearing the east bank of the canal, units of the 11th Division crossed at four places between Sains-lez-Marquion and the highway and moved smoothly into place on the left of the 1st Division to start the second phase of the attack. The advance to the north and north-east continued without serious interruption, and by dusk Epinoy and Oisy-le-Verger were in British hands.
