Battle of Cambrai

Short Summary:

BATTLE OF CAMBRAI (Nov. 20 - Dec. 3, 1917). As a possible solution to the breaking of the stabilized front, the British launched a massed attack of almost 500 tanks at dawn on November 20. Cavalry followed closely to exploit the hoped-for breakthrough. The attack gained spectacular initial successes, but by nightfall the tanks and cavalry had become stalled along the difficult St. Quentin Canal. For the next few days bitter fighting took place for Bourlon Wood; by November 26, the advance had progressed only to the line shown. On November 30, an overwhelming German counterattack drove the British steadily back. By December 3, they had stabilized their lines, retaining some ground gained in the center, but losing an equal amount of their original holdings to the south. This first massed tank attack had failed, but it indicated great promise for the future.

------------------------------------

As the year 1917 drew to its end, Haig realized that at most one more offensive would be possible before he and the French faced the full flood of the German divisions set free by the Russo-German armistice. By the end of October, he was doubtful whether even that much would be possible. Between October 24 and November 11, Austro-German forces won a brilliant victory over the Italians in the Battle of Caporetto (now Kobarid). The rout ended on the Piave River after 11 Franco British divisions had been sent to Italy from the western front, but before they had been in action.

Meanwhile, Haig's problem was that he was still unsure of how many troops he would have to send to Italy (actually, the British contingent was reduced to 5 divisions, whereas the French sent the original quota of 6). This anxiety was, however, mild by comparison with his satisfaction that tanks were at last to be used as their creators had foreseen, and that he could allot the Third Army of Gen. Sir Julian H. G. Byng (later 1st Viscount Byng) 324 tanks, as against the 48 in action at Arras. Moreover, owing to new artillery methods, especially sound rangmg and flash spotting, every German battery could be pin-pointed, a preliminary bombardment could be dispensed with, and complete surprise could be achieved for the first time.

At 6:20 A.M. on November 20, the fire and the advance of the tanks began simultaneously. By evening the advance exceeded three miles, and it might have been far greater but for the one calamity of the battle at Flesquieres, where a single German field battery knocked out tank after tank as they breasted the rise, and the supporting infantry could not force a way through the wire of the Hindenburg Line while it remained uncut. The battle now resolved itself into a fight for the height surmounted by Bourlon Wood, which was taken and retaken.

Ludendorff saw exactly what was required. He massed his reinforcements on the flanks of the bulge between Banteux and Moeuvres and directed Gen. Georg von der Marwitz, commanding the Second Army, to eliminate it by convergent thrusts. Marwitz struck at 8:30 A.M. on November 30, after a bombardment maintained all night and on the southern flank won a great victory. The German infantry had never fought with greater enthusiasm or tactical skill. Disdaining the heights which commanded the valleys, it made use of these to paralyze the defense. The attack not only smashed the British array on the new front, but captured the original position farther south on a frontage of three miles. The Guards Division recovered Gouzeaucourt, however, and brought the enemy's advance to a halt.

The same tactics were employed on the northern flank, but on more open ground with better observation they did not meet the demands of the situation. The guns were firing over open sights, shooting the successive waves to fragments, and when the accompanying batteries strove to unlimber, they laid out the horses so that the guns were thenceforth stationary. Prince Rupert and Marwitz called off the battle on the night of December 1. Between December 4 and 7, Haig had to yield a few more of his gains in order to obtain a defensible front based on the Hindenburg Line. His losses totaled 43,000 men, including 6,000 prisoners taken on the first day of the counteroffensive; those of the Germans, 41,000 men, including 11,000 prisoners. The British public, which had listened to the premature ringing of church bells, was bitterly disappointed by the reversal of fortunes and staggered by the loss of guns: 158, as contrasted with 138 taken from the Germans.

The most interesting feature of Cambrai was its significance for the future. The tactics and strategy of World War II were first developed in this battle, and the victories of 1918, beginning with the reduction of the Amiens salient on August 8-September 3, depended on it to an equal extent.
