A Canadian Deception

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).

Although by August 13 1918 the Allied offensive had been definitely checked, the German leaders could no longer doubt that the initiative had passed from their hands. On that date, at a conference held at Spa with Field-Marshal von Hindenburg, Reichschancellor Count von Hertling and the Foreign Secretary, Admiral von Hintze, in attendance, Ludendorff, while opposing any voluntary surrender of ground, admitted "that it was no longer possible to force the enemy to sue for peace by an offensive". Since the defensive alone could hardly achieve that object, the war would have to be ended by diplomatic means. Hindenburg, on the other hand, derived some comfort from the fact that "the enemy had once more failed to extract all possible advantages from his great initial successes" and that German armies were "still standing deep in the enemy's country." Next day, at a Crown Council presided over by the Kaiser, His Majesty ordered peace negotiations to be opened through the King of Spain or the Queen of the Netherlands.187 It was also about this time that orders were issued calling off large-scale air attacks planned against the British and French capitals by German bombers using thousands of one-kilogram incendiary bombs. While it was proclaimed to the world that these cities were being spared on humanitarian grounds, there seems little doubt that the inevitability of a German defeat was the main reason for the cancellation of the attacks. Throughout the war British and French planes dropped some 14,000 bombs on German soil. A British plan to attack Berlin, however, failed to materialize owing to insufficient aircraft capable of such a mission.

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
Armies.

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".

The success of the Amiens offensive had convinced Haig that the time had come for an all-out effort against the enemy-who was "feeling that this is the beginning of the end for him". In the C.-in-C.'s opinion bold action should replace unenterprising caution. He told his army commanders to emphasize to their subordinates the changed conditions under which they must now fight. It was no longer necessary "to advance step by step in regular lines as in the 1916-17 battles. All Units must go straight for their objectives, while Reserves should be pushed in where we are gaining ground."

The first move in the Allied scheme to extend the stalled Amiens offensive on both wings was made on the southern flank on August 20 1918, when the French Tenth Army of General Mangin struck northward from the Aisne between Compiègne and Soissons with twelve divisions. An advance of nearly five miles in two days carried the assault to the river Oise between Noyon and Chauny. On the 21st the French Third Army (General Humbert) on Mangin's left resumed operations with some success, while on the same day north of Albert the British Third Army initiated Sir Douglas Haig's share in the renewed offensive. General Byng's forces struck a telling blow on the 23rd, when a two-mile advance towards Bapaume netted 5000 prisoners from General Otto von Below's badly shaken Seventeenth Army. This achievement was matched on Haig's right flank, where the Fourth Army had taken up the battle astride the Somme and the 1st Australian Division had shattered two German divisions on the southern bank. The next two days saw some slight progress on both the Third and Fourth Armies' fronts, and on August 26 an expansion of the battle into the First Army's sector brought the Canadian Corps once more into action.

The period of rest and refitting that would normally follow participation in such extensive operations as the Amiens battle was denied the Canadians; for in these last hundred days of the war each major offensive so rapidly succeeded its predecessor that unprecedented demands had to be made on the stamina of the forces employed. Back under General Horne's command in its former position east of Arras, the Canadian Corps was confronted by a series of formidable defence positions which the enemy was holding in strength. Immediately in front of the Canadians, about Monchy-le-Preux, were the old British trenches lost in the German offensive of March 1918, and to the east of these lay the enemy's former front line. This was backed up, two miles east of Monchy, by the so-called Fresnes-Rouvroy line, which was actually an extension south of the Scarpe of the original line joining Rouvroy (south-east of Lens) to Fresnes (north-east of Arras). Another mile to the east the approaches to Cambrai were blocked by the strongest position of all-the Drocourt-Quéant line (the southernmost portion of the Wotan I-Stellung), which, extending northward from the Hindenburg Line (Siegfried-Stellung) at Quéant, had been constructed by the Germans to contain any Allied advance into the Douai plain. Still farther east, crossed by the main road at Marquion, was the unfinished Canal du Nord, connecting the Somme Canal with the Sensée Canal. Though not yet extensively fortified it formed in conjunction with the Sensée marshes a major obstacle.

On August 22 General Currie outlined to his divisional commanders his plans for an attack eastward astride the Arras-Cambrai road. The Canadian Corps had been given the task of forcing the Drocourt-Quéant line south of the Scarpe and advancing to the line of the Canal du Nord. Having thus broken the hinge of the Hindenburg system the Corps was to swing southward and sweep down behind that formidable position in order to deny the Germans opposing the Third Army a rallying ground. On Currie's right the 17th Corps, operating on the Third Army's northern flank, was under orders to cooperate with the Canadian Corps, attacking south-eastward along both sides of the Hindenburg position.

General Currie's was an important and a difficult assignment. The enemy's main defence positions, supplemented by various subsidiary switches and strong points, were among the strongest on the Western Front. The ground was pocked with the scars of 1917 and early 1918, and in the litter of old trenches and fortifications German engineers had found ready-made positions which they had considerably strengthened. Furthermore, topography was on the side of the Germans. The battle area spread over the north-eastern slopes of the Artois Hills, whose summits about Monchy were over three hundred feet above the valley-bottoms of the Scarpe and the Sensée. The latter river, flowing generally eastward, together with its tributaries had dissected the hills into numerous deep valleys. The intervening ridges and high points, often mutually supporting, the enemy had fortified with a skill that demonstrated his mastery in military engineering.

The Germans' general defensive plan at this time was to give up ground in the region of the Lys and Ypres salients and to fight a determined rearguard action in the Somme area. Ludendorff overruled the views of those staffs (in particular Crown Prince Wilhelm's) that favoured a major voluntary retirement into the Hindenburg and adjoining defence systems. His purpose was by means of a gradual fighting withdrawal to wear out the Allied forces before they reached the Hindenburg position, thus gaining time to reorganize behind that formidable defence line. The defences about the Arras-Cambrai road in the Monchy area would form the pivot of any German retirement south of the Scarpe, while the security of Prince Rupprecht's northern armies also depended on retaining them.

These positions became the initial Canadian objective. With the enemy expecting attack, except for the actual hour of assault, surprise was clearly impossible. It would be a case of launching successive frontal, grinding assaults against well-established lines manned by tenacious, alert troops.
