1918 General Rawlinson’s Fourth Army, spearheaded by the Australian and the Canadian Corps, launched the attack at Amiens. Rawlinson used over 2,000 guns, 450 tanks and 1,900 aeroplanes to support the attack by 13 divisions. Through careful preparations, the Allies achieved complete surprise.

Their tanks broke through the German lines and sowed panic in the rear. The battle illustrated that the British had perfected how to combine infantry, artillery, tanks and aircraft in a co-coordinated attack.
