The conformation of the country about Graf and Meetcheele made the arrangements of a really effective barrage a highly technical affair. In that district of swamps and hills and copses it was impossible that our line should be straight, and on the night before their offensive the men of the P.P.C.L.I. were compelled to establish their assembly position close in rear of the front line. This enabled our artillery to place a heavy barrage just before our attacking troops without too much risk of casualties among our own men. On the morning of October 30th, when the Princess Pat's went forward to the attack upon Graf and Meetcheele, our artillery fire was effective enough, and good progress was made, though our casualties were heavy. Stubborn bayonet fighting took place about the enemy's pill-boxes on the flanks of the hill, and along the valley of the Ravebeek, where the heavy smoke barrage covered the right of our advance. For a time all went well: but the enemy's fire was close and intense, and our men suffered so heavily that for a time it seemed as if our advance might die out through sheer numerical weakness. But we kept on, and reached the foot of the hill at Meetcheele before a really serious check was encountered. A German pill-box was situated upon the top of the hill, and all the higher ground was dotted with the machine-gun emplacements of the enemy. From the commanding position of the concrete fort upon the crest, direct observation could be obtained over our whole local advance, and the sweeping fire of its guns inflicted casualties upon our men attacking half-a-mile away, who were in complete ignorance of the existence of such a strong point. As in many cases during the Passchendaele fighting, the front of this attack was dangerously narrowed by marshy ground on each side of a dry spur leading direct to the top of the hill. It is an interesting fact to consider that the Germans, after the first Canadian attack, altered the zones of fire of a number of their machine-guns so as to cover swamps and marshy ground that previously had been considered impregnable from their natural difficulties. This was a real compliment to our men--for apparently the enemy thought the Canadians quite capable of attacking over ground impassable to other troops. However, in this case, the Princess Pat's fought their way up the slope until most of their effective strength was gone; and then Sergeant Mullin went forward to reconnoitre the possibilities of a flanking attack. Finding a place where one man could advance unobserved, but where the movement of a party would certainly bring disaster, he made his way forward alone.
