Pieces of History
Military Logistics of the Canadian Expeditionary Force, 1914–1919
Canadian military logistics is a dimension of the history of the Canadian Expeditionary Force (CEF) that is often overlooked. Yet just a few days after Canada’s entry into the First World War, it was obvious that there was no way of ignoring it. When huge numbers of military and civilian volunteers showed up at Valcartier, near Quebec City, in August 1914, logistical support services, which had only recently been established, were soon put to the test. Clothing and equipping the members of the first contingent turned out to be a real headache. Manufacturers had to be found and contracts drawn up in a hurry for the production of uniforms, boots, belts, weapons, vehicles and so on. From a logistical standpoint, mobilizing the first contingent destined for Europe was a nightmare.
Throughout the Great War, the Canadian Expeditionary Force’s logistical support system was an immense, complex operation. Of all the support services, the Canadian Army Service Corps (CASC) was the most diversified. Its main responsibilities were transporting combat troops, delivering equipment and materials, and providing the troops with fresh supplies. In addition to these essential tasks, the CASC also evacuated the wounded (ambulance drivers belonged to the corps), salvaged equipment that had been captured from the enemy or left behind on the battlefield and delivered mail. The CASC worked closely with the Canadian Ordnance Corps, the Canadian Army Medical Corps, and the Canadian Artillery Corps for the transportation of specialized ordnance.
The CASC operated from seaports located hundreds of kilometres from the battlefield, all the way to just behind the front lines. Its replenishment system could supply not only small groups of just a few men but also formations the size of an infantry battalion (approximately 1,000 men).
Resupplying front-line units was a multistep process. From ports and depots, supplies were first taken by railway to railheads. From there, CASC units were responsible for moving the supplies by truck or light railway to supply dumps. These operations took place in the third line of supply. Thanks to their small size, light railways could run and reach areas closer to the front lines more easily. It was also harder for enemy artillery to pinpoint them. The administrative area behind the front lines was crisscrossed by light rail lines that were built and maintained by Canadian railway troops.
From the supply dumps, the CASC’s divisional train and ammunition supply column, both of which were horse-drawn, were responsible for bringing supplies closer to the front lines, to their respective divisions or individual units. This was the second line of supply.
Lastly, operations to supply front-line units constituted the first line of supply. These units had to come back to the rear to get their own supplies of gear, ammunition, weapons, technical and communications equipment, water, medication and food. These supply expeditions were carried out chiefly at night so that the soldiers could not be seen by the enemy. But assigning combat troops to this task meant that a battalion’s defensive positions at the front would be short of manpower for a time and so vulnerable to enemy attack.
Toward the end of the war, however, a Canadian officer from Montreal proposed using the tumpline system — the method that Canada’s aboriginal people and coureurs de bois had used to carry large loads on foot. Before the introduction of this system, infantryman had to carry supplies in their arms, thus limiting the quantity of materials due to their size and weight. The tumpline system, which involved the use of a head strap, allowed the soldiers to carry more weight and freed up their arms, thus giving them more freedom of movement. With this system, each soldier was able to transport a greater quantity of supplies and so fewer men were required for the job, leaving more troops to ensure the defence of the front lines.
Besides regularly providing drivers and vehicles to other units, the CASC also maintained and repaired its vehicles. It also had to make sure that the troops were fed, which meant that fresh and hard rations had to be allocated and distributed properly; its military cooks oversaw the operation of field bakeries and butcheries.
The CASC was not the only logistical support corps to play a key role in the CEF. The Canadian Ordnance Corps was responsible for procuring, storing and distributing uniforms, boots, equipment, weapons, ammunition and shells to combat troops. Specialized supply depots, located in the second line of supply, helped ensure more effective distribution.
The Canadian Ordnance Corps’ other major role was to maintain equipment in the field. The repairmen in the specialized ordnance mobile workshops could get closer to the deployed units and repair their weapons, both light and heavy, as well as their equipment. If the mobile workshops were not able to do the repairs on site, the weapons and equipment were shipped to heavy or stationary workshops at the rear, where virtually anything could be reassembled or rebuilt. The small detachments of the Ordnance Corps worked closely with the various units of the Army Service Corps.
Despite the gradual mechanization of the war, horses remained a vital component of the CEF. The cavalry, the artillery and, of course, the Army Service Corps used huge numbers of horses right up to the end of the war. At one point, Canadians were using as many as 24,000 horses and mules in their overseas operations. Horses could often manage in places where motorized vehicles could make no headway! Inevitably, some horses suffered injuries or fell ill. The Canadian Veterinary Corps operated mobile sections to take care of horses; it also ran veterinary hospitals for horses, advanced remount depots and specialized basic provisions depots.
Other logistical support services also played a crucial role in enabling combat troops to get on with their job. The Canadian Postal Corps, for instance, helped maintain the morale of soldiers at the front, at the rear and also those convalescing in hospitals. Army chaplains, who constituted the smallest organized support group, provided religious services to Canadian soldiers of different faiths and offered moral support at difficult times. Lastly, despite the enemy’s efforts to maintain a naval blockade by submarines, the Canadian Forestry Corps ensured that Great Britain, France and the Canadian Expeditionary Force obtained all the timber they needed to carry out their military operations.
Thousands of men served in these various organizations. The Army Service Corps, for example, counted over 17,000 officers and non-commissioned soldiers in its organization. Even if these units were not combat troops, many of them, including the Army Service Corps, played important roles in all military actions. One hundred and four members of the CASC were killed, and 363 were wounded.

Life in the Trenches
Historian, Canadian War Museum
From Switzerland to the North Sea, some 500 kilometres long, soldiers on both sides carved out ditches in the ground that, over time, were expanded in complexity and depth. By 1915, vast underground cities housed the soldiers, as the opposing armies faced off against each other across no man’s land. Along this continuous line of trenches, offensive operations degenerated into frontal assaults, which were usually stopped dead by concentrated fire.
The Western Front, as it was called, consisted of a series of trench systems in depth. The front lines were held in strength, but behind them, joined by a series of communication trenches that ran perpendicular to the front, were support and rear trenches. Deep protective dugouts were situated along the front and rear trenches to provide some degree of safety against all but direct hits from artillery fire. Saps and listening posts were pushed into no man’s land, where soldiers were positioned to provide advance warnings of enemy attacks.
Despite the unsanitary nature of front line trenches, they were areas of safety. The trenches protected against small arms fire, shrapnel bursts and high explosive bombardments. Every day and night soldiers shored up the crumbling walls, filled sandbags, and rebuilt sections that had been damaged by artillery fire. It was not only a war of the machine gun and rifle, but also of the shovel.
Life in the trenches was filled with long periods of boredom interspersed with terror. Much of the time was spent in routine duty. At half an hour before dawn, the infantry was roused from their dugouts or funk holes (small spaces carved into the trench walls) and ordered to ‘Stand-To.’ At the alert, they waited for a possible attack with bayonet fixed. If nothing occurred, and it rarely did, since the infantry of both sides were always at their most prepared at this time, officers inspected the men. Rifles were examined for rust; feet were prodded to ensure that dry socks had been worn to protect against trench foot. The latter being a type of frostbite that occurred from prolonged standing in cold, slushy water, and could, in severe cases, require the amputation of toes or feet. After inspection, soldiers were often rewarded with a small dose of rum, which was much appreciated by the men, who saw it as a form of medicine to help withstand the daily deprivations.
Breakfast, like most meals, usually consisted of canned beef, jam and biscuits. It was a monotonous diet, but soldiers rarely went hungry. For lunch or dinner, soup or stew was brought up from rear areas to offer some variety and warmth. Care packages from home, filled with cheese, bread and sweets, augmented the bland food. During the day, though, the goal of most privates was to avoid the sergeant who assigned trench chores. Most were unsuccessful, with soldiers spending much of their time rebuilding the trenches or standing sentry.
Despite these duties, soldiers had much free time, during which they dreamed of home and of loved ones left behind; worried about children who were growing up without a father; of ailing parents with no caregivers; or of a wife who was trying to feed a family with insufficient funds. Literate soldiers might spend a few hours scribbling letters. Return mail from home was a welcomed treat, with letters read and reread. These exchanges back and forth remained an important life-line to Canada from the trenches. And while they were usually subject to two levels of censorship, by officers at the front and officials in England, soldiers nonetheless tried to share their thoughts with those at home. Civilians could not understand everything, nor could soldiers often capture the full range of their strange experiences in words, but letters remained an important avenue of expression.
Boredom could be kept at bay through gambling, and there was always some rake with dice or cards to fleece his mates. If a soldier had no money, he at least had cigarettes. Soldiers smoked all day long, and cigarettes, which were issued by the army, bought in rear areas, and begged from those at home, were a useful distraction. They helped to calm the nerves, or so soldiers said, and they certainly helped to mask the stench of unwashed bodies.
There were no baths in the front lines and, most soldiers went at least a week, usually longer, without changing their clothes. Dirt and mud were a part of life and, during the winter, helped to insulate soldiers. Far more trying was the infestation of parasitic body lice. The lice lived in the seams of clothing where they feasted on human blood. Soldiers scratched themselves raw to get at their infernal enemies. They learned to defeat their insect adversaries, at least for a time, by taking off their shirts and running a candle over the seams. This drew out the lice that were then squashed satisfactorily between finger and thumb. While soldiers did this, they would sit around, talk, complain and gossip. It was known as ‘chatting,’ and it is just one of many wartime phrases that would enter the English lexicon. But the lice always came back, tormenting the soldiers day and night.
Rats, too, were a constant plague, and because they lived off corpses, they could grow as big as cats. They bit soldiers and scurried over their faces while they slept. The rats were hunted by soldiers and their trench pets, usually fierce terrier dogs, but the rodents lived in and outside of the trenches and were always multiplying. Their squealing movement could be heard throughout the battlefield.
Amidst the mud and slush in the winter, or heat and flies in the summer, soldiers developed their own trench culture. New words sprang up, slang like ‘napoo’ for being killed, or ‘blighty’ that referred to England or home. Artistic soldiers could take spent ammunition and shape it into art. Some soldiers tried their hand at poetry. While most were not as skilled as John McCrae, Wilfrid Owen or Siegfried Sassoon, to name the best-known war poets, the trench poetry or doggerel provided much insight into the soldiers’ front-line experiences. At the group level, some battalions printed trench newspapers. Drawing from their own soldiers in the ranks—men who in civilian life had been editors, journalists and cartoonists—these crude newspapers contained rough humour and wry commentary on the strange, subterranean world of the trenches.
But just as a soldier might be penning a letter or staring at the blue sky above, the crash of an artillery shell could bring sudden death. The enemy was always there to kill or maim. Snipers skulked into no man’s land, camouflaged and ready to put a bullet through a man’s head should it rise, even for a second, above the safety of the trench parapet. Poison gas was released in the form of gas clouds and artillery shells, and soldiers who could not put on their respirator quickly faced a lingering death as chemicals corrupted and ravaged lungs.
Machine-gun bullets raked the front lines day and night. Yet artillery shells were the greatest killer in the war, accounting for more than half of all deaths. High explosive shells blew deep holes in the ground or wrecked trenches; soldiers were atomized by direct hits. Equally deadly, shrapnel artillery shells rained hundreds of metal balls and jagged steel down on soldiers, shredding through flesh and bone. Steel helmets, introduced in early 1916, helped to reduce casualties, but a unit’s tour in the front lines almost always resulted in a steady hemorrhage of casualties. It was clinically called wastage, and impersonal charts showed that each month the infantry would lose approximately 10% of its strength, even in quiet areas where no operations were carried out. While the snipers and artillerymen did their dirty work, the soldiers could look around and see their best friends killed and maimed.
Yet the soldiers struck back in the form of nighttime raids. Changing into dark clothes, equipping themselves with revolvers, grenades, daggers and clubs, small groups of men snuck past their wire and into no man’s land. Raids were a form of organized mugging, and the goal was to gather intelligence, kill the enemy and grab a prisoner. Enemy sentries were usually the target, but sometimes large groups of raiders slipped into the opposite trenches to wreck mayhem. While Canadian troops acquired a reputation as fierce raiders, these operations were dangerous affairs, and in the confusion of night fighting, casualties were often heavy.
To help relieve the unending pressure on soldiers, they were rotated in and out of the front line. On roughly four- to six-day tours, filthy, verminous, exhausted soldiers passed from front to secondary lines and finally to the reserves. This rotation helped to relieve the strain, but soldiers always knew they would return to the trenches in this maddening cycle.
Endurance was the key to survival and soldiers learned to cope with the inhuman conditions. Some developed fatalistic attitudes, believing they would be killed ‘when their number was up’; others lived in terror all the time; a few hoped for a blighty wound, a bullet through the hand or leg that would take them away from the horror and back to a clean hospital in England. Thousands suffered mental breakdowns, known as shell shock, but hundreds of thousands more of the ‘poor bloody infantry,’ as the soldiers liked to call themselves, learned to withstand the strain of the trenches. And it was these survivors who, after four years of bitter fighting, would finally break the static warfare on the Western Front and defeat the German forces.

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.
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
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
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.

Engineers on the Western Front
Historian, Department of National Defence
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.
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.
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.
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.

Artillery: The Great Killer
Historian, Canadian War Museum
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.

Unending Seige : Amiens
The scene was now set for toppling the German militarism that in various forms had kept Europe trembling for more than 50 years. Over the long, painful weeks the Allies lived through in the spring of 1918, the Canadians had learned much. They had also had time to rebuild their strength after the successful but costly attacks of 1917.
The sector now reserved for them was that around Amiens. To give the Canadians the advantage of surprise, they were taken 60 kilometres north of the city. Accustomed to having the Australians opposite Amiens, the Germans also knew the Canadians, whom they had seen spearheading British assaults. Two battalions and two first-aid stations were set up in front of Kemmel, where constant traffic of assorted messages was set in motion and picked up by the Germans. Between 30 July and 4 August, in deepest secrecy, the rest of the Canadian Corps descended to the south. Their discretion was facilitated by the gloomy weather, which reduced German air sorties, and the fact that only the division commanders knew the assault target. This secrecy caused numerous logistical problems - for example, the artillery would have almost no time to prepare. Opposite Amiens, the Canadian officers studying the terrain fooled the Germans by wearing the trademark soft hat of the Australian soldiery.
The noise of preparations for the largest mechanized battle ever seen up to that time revealed nothing to the enemy. In spite of all the precautions, however, some German units were wondering about the movements they had detected. Some 604 tanks of all kinds and thousands of horses would give the battle an aspect that was both ancient and modern.
The Black Day of the German Army
Just before dawn on 8 August the attack opened with the firing of 2,000 guns. In addition to the tanks, the soldiers could rely on two motorized machine-gun brigades, a battalion of cyclists to serve the Corps and a section of heavy mortars mounted on trucks. A thousand French and 800 British planes took to the air. During this brilliant assault, which would seriously undermine the morale of the German troops, the Canadians advanced 13 kilometres at the head of an immense front more than 30 kilometres wide. Australians, British and French were also in the attack, their role being to keep clear of the advance of the Canadians, who had more ground to cover to reach their objectives. The Canadians lost 1,036 men killed, 2,803 injured and 29 taken prisoner, losses that were largely offset by their remarkable advance, the most impressive on the western front since 1914. The Germans had to accept 27,000 casualties, including 16,000 taken prisoner - 5,033 of them taken by the Canadians, who also seized 161 artillery pieces and a large number of machine guns and anti-tank guns. Though the Allies were left with only 132 tanks to start with the next day, the Germans had lost seven divisions. The confidence of their High Command was shaken by the realization that its war machine was no longer effective.
An interesting experiment that day involved the use of 30 Mark V tanks to transport the troops of the 4th Division to the opposing trenches. However, many men were bothered by the heat and by the exhaust fumes that entered the passenger compartment. A few fainted; others got out and walked. The drawbacks associated with the Mark Vs could not be rectified and these tanks were not used again during that war.
Canadian Corps Advances
During the night of 8/9 August, the British High Command decided to lend its 32nd Division to the Canadians, who wanted to withdraw their 3rd Division from the front. The Canadians of the 3rd Division had already marched about 10 kilometres to the rear when they were recalled, as the British had changed their minds. The men were exhausted on their return. It was therefore decided to use only one of their brigades at the front, which required the 1st and 2nd divisions to expand the sectors they were covering. Under these conditions the attack of 9 August could not get under way until around 11 am, without the element of surprise of the day before. At a cost of 2,574 casualties, the Canadians took 6.5 kilometres of ground.
The pressure continued to mount for several days, but the momentum of 8 and 9 August was indeed lost. The number of available tanks fell to the point where, on the 12th, there were only six left. Despite their 11,725 casualties from 8 to 20 August, the Canadians had sounded the beginning of the end of the German army by advancing nearly 30 kilometres and securing the ground thus taken. In the whole operation, the Germans recorded 75,000 casualties.
A month earlier the French had seized the initiative from the Germans. In this context, the battle of Amiens would have a decisive impact. It shattered the last hopes of the German High Command, along with any confidence they might have had that their troops still wanted to fight. The success of the Canadian troops was based partly on surprise, the concentration of their strength and co-ordination among the various arms (planes, tanks, guns, machine guns).

In the meantime Allied plans on the Western Front were undergoing revision. As early as the evening of August 11, as German resistance stiffened, Marshal Foch had shown himself willing to modify objectives and consider alternatives to further offensive operations on the Amiens front. At that time large-scale operations were due to be resumed on the 15th. But on the 13th General Debeney asked for and received a day's postponement of the assault by his army; and next morning General Rawlinson was given the same extra time in which to complete his preparations. Sir Douglas Haig has revealed in his diary that he shared Rawlinson's misgivings about attacking the well-prepared Roye-Chaulnes defences and that he was resolved that the French First and British Fourth Armies should merely "keep up pressure on that front" in order to hold the enemy's attention, while he prepared to strike elsewhere with the British First and Third
There is no doubt that Rawlinson was considerably influenced by representations made to him by General Currie, upon whose forces the burden of a major share of a renewed offensive must fall. At a meeting on the morning of August 14 the Army Commander showed Haig a letter (accompanied by air photographs taken the previous day of the German positions) in which Currie set forth the arguments against renewing an operation which would "cost a great many casualties" without obtaining adequate results. He suggested that if the attack were found to be absolutely necessary it should be postponed in order to allow time to "recover the element of surprise." He recommended that an alternative, and better, course would be to withdraw the Canadian Corps from the line, and after resting it for a few days employ it on the Arras front in a surprise attack in the direction of Bapaume. An advance in this sector coupled with an attack by the French from their present line, might well force the enemy to abandon his positions west of the Somme without the necessity of a frontal assault.
This last suggestion was in keeping with Haig's own ideas. An exchange of letters with Foch on the 14th brought no agreement about postponing operations at the Somme, and that evening a telegram from the Generalissimo asked Haig "once more to maintain the date already set." The Field Marshal, however, had made up his mind to limit the Somme attack to a series of set stages, and on the afternoon of the 15th he pressed his arguments at Foch's advanced headquarters at Sarcus (twenty miles south-west of Amiens). "I spoke to Foch quite straightly", his diary records, "and let him know that I was responsible to my Government and fellow citizens for the handling of the British forces." Foch's resistance had already been weakened when he learned from General Debeney that morning that the projected attack on Roye "would certainly be difficult", and even if mounted would leave the French forces too weak to maintain it. "I definitely came around to the opinion of Field-Marshal Sir Douglas Haig", he wrote in his Memoirs, and he agreed that the Amiens offensive should not be pressed.
A new operation order issued by British G.H.Q. directed the Third Army, which was holding a nineteen-mile front north of Albert, without delay to "press the enemy back energetically in the direction of Bapaume"; the Fourth Army while continuing its preparations for an attack would be prepared to follow up any German withdrawal towards the Somme. Farther north the First Army would take advantage of any German retirement to exert pressure south-eastward from the Arras sector; under favourable conditions, it would attack Monchy-le-Preux and Orange Hill.
In a letter confirming his acceptance of Haig's proposals Marshal Foch made it clear that he was depending on the British operations to be developed with sufficient impetus to ensure a resumption of the thrust south of the Somme. He went on to thank Sir Douglas for his cooperation, which had completely freed the Amiens area and the Paris-Amiens railway. For an offensive north of the Aisne he was now going to transfer the French First Army from Haig's command back to Pétain's group of armies. Accordingly the Franco-British boundary was shifted northward to the Amiens-Chaulnes railway, and the relief of the Canadian Corps by French troops began on 19 August.
On the night of August 19-20 the 2nd Canadian Division began moving northward by bus and train to rejoin the First Army in the Arras sector, followed the next night by the 3rd Division. A number of days were to elapse before the 1st and 4th Divisions made the move. General Currie closed his Headquarters at Dury on the 22nd. During the day he called on a number of senior commanders and had the satisfaction of being told by General Byng that the Canadian performance at Amiens was "the finest operation of the war".
