The last stages of this Third Battle of Ypres were probably the muddiest combats ever known in the history of war. It rained incessantly, sometimes quieting to a drizzle or a Scots mist, but relapsing into a downpour on any day fixed for our attack. The British movements became a barometer. Whenever it was more than usually tempestuous it was safe to assume that some hour of advance was near. The few rare hours of watery sunshine had no effect upon the irreclaimable bog. "You might as well," wrote one observer, "try to empty a bath by holding lighted matches over it." On the 30th October our line was sufficiently far advanced for the attack on Passchendaele itself. On that day the Canadians, assisted by the Royal Naval Division and London Territorials, carried much of the Ridge, and won their way into the outskirts of Passchendaele village. Some days of dry weather followed, and early in the morning of 6th November the Canadians swept forward again and carried the whole main ridge of West Flanders. By this achievement the Salient, where for three years we had been at the mercy of the German guns, was no longer dominated by the enemy position. The Third Battle of Ypres was strategically a British failure; we did not come within measurable distance of our main purpose. But that was due to no fault of generalship or fighting qualities, but to the malevolence of the weather in a country where the weather was all in all. We reckoned upon a normal August, and we did not get it. The sea of mud which lay around the Salient was the true defence of the enemy. Ypres was to Britain what Verdun was to France—hallowed soil, which called forth the highest qualities of her people. It was a battleground where there could be no retreat without loss of honour. The armies which fought there in the Third Battle were very different from the few divisions which had held the fort during the earlier struggles. But there were links of connection. The Guards, by more than one fine advance, were recompensed for the awful tension of October 1914, when some of their best battalions had been destroyed; and it fell to Canada, by the victory of Passchendaele, to avenge the gas attack of April 1915. when only her dauntless two brigades stood between Ypres and the enemy. *CHAPTER IX.* *THE TANKS AT CAMBRAI.*
