In the Globe and Mail, J.L. Granatstein wants us to remember the greatest military achievement of the Canadian Corps in World War One (and it isn’t the battle of Vimy Ridge):
On Aug. 8, 1918, the Canadian Corps had secretly moved into position in front of the French city of Amiens. The German army had been on the offensive since March, and the Amiens sector was rather lightly defended. The Canadians, British and Australians struck this sector a surprise hammer blow in the early morning, a hurricane of artillery fire clearing the way for the tanks and infantry that blasted through the defences. Thousands of Germans surrendered, more were killed and within a few hours, the Canadian advance was almost 15 kilometres. This, wrote the German army’s great strategist, General Erich Ludendorff, was “the black day” of the German Army.
Lt.-Gen. Currie’s troops then moved north to the Arras area, where, at the end of the month, they struck toward and then through the Drocourt-Quéant Line, an immensely strong extension of the Hindenburg Line defended by crack troops. In heavy fighting at high cost, the Corps broke the line, forcing the Germans back behind the Canal du Nord, their last position protecting the key supply point of Cambrai.

The Germans now were in full retreat, moving eastward as fast as they could go. The Canadians took Valenciennes, smashing the enemy defences with a massive artillery barrage, and then moved into Belgium. By Nov. 11, they were in Mons, the same small town where the men of the British Expeditionary Force had first faced the invading Germans in August, 1914.
The Canadian Corps, more than a hundred thousand strong, had fought its last battles. As Lt.-Gen. Currie noted proudly, it had beaten 47 German divisions since Aug. 8, a quarter of the German forces in the West. The Corps had accomplished this because of its great fighting spirit, its fine leadership at all levels and its effective reinforcement and logistics systems. The cost in lives and in wounded was terrible — 45,000 casualties, 20 per cent of the total of Canadian losses in the entire war — but for once, the campaign had achieved measurable gains on the ground. More than that, the Canadian shock troops had battered the enemy, forced them eastward and obliged them to seek an armistice that was a de facto capitulation. It had scored its greatest victory, the greatest battlefield triumph ever by Canadian troops.
