Many lessons the Canadians had to learn about organization and staff work, about details of discipline which make for homogeneity of action, and the divisions that came to join the first one learned their lessons in the Ypres salient school, which gave hard but lasting tuition. I was away when at St. Eloi they were put to such tests as only the salient can provide. The time was winter, when chill water filled the shell-craters and the soil oozed out of sandbags and the mist was a cold, wet poultice. Men bred to a dry climate had to fight in a climate better suited to the Englishman or the German than to the Canadian. There could be no dugouts. Lift a spade of earth below the earth level and it became a puddle. It was a wrestling fight in the mud, this, holding onto shell-craters and the soft remains of trenches. The Germans had heard that the Canadians were highstrung, nervous, quick for the offensive, but badly organized and poor at sticking. The Canadians proved that they could be stubborn and that their soldiers, even if they had not had the directing system of an army staff that had prepared for forty years, with two years of experience could act on their own in resisting as well as in attacking. "Our men! our men!" the officers would say. That was it: Canada's men, learning tactics in face of German tactics and holding their own! When all was peaceable up and down the line, with the Grand Offensive a month away, the Germans once more "tried it on" the Canadians in the Hooge and Mount Sorrell sector, where the positions were all in favor of the Germans with room to plant two guns to one around the bulging British line. For many days they had been quietly registering as they massed their artillery for their last serious effort during the season of 1916 in the north. Anything done to the Canadians always came close home to me; and news of this attack and of its ferocity to anyone knowing the positions was bound to carry apprehension, lasting only until we learned that the Canadians were already counter-attacking, which set your pulse tingling and little joy-bells ringing in your head. It meant, too, that the Germans could not have developed any offensive that would be serious to the situation as a whole at that moment, in the midst of preparations for the Somme. Nothing could be seen of the fight, even had one known that it was coming, in that flat region where everyone has to follow a communication trench with only the sky directly overhead visible. There was an epic quality in the story of what happened as you heard it from the survivors. It was an average quiet morning in the first-line trenches when the German hurricane broke from all sides; but first-line trenches is not the right phrase, for all the protection that could be made was layers of sandbags laboriously filled and piled to a thickness sufficient to stop a bullet at short range.
