Meanwhile, the 9th Inniskillings, responsible for the next phase of the attack after the 10th had captured Hill 90, had moved in. Those only who have seen the Hindenburg trenches can realize how comparatively easy it was to pass one body of troops through another in them. In ordinary trenches such methods would have resulted in hopeless congestion. Here all went smoothly owing to the great breadth of the trenches. The 9th Inniskillings had one platoon moving along the bed of the Canal, here dry. Craters on the Demicourt-Graincourt Road, defended by machine-guns, caused trouble, but the right companies pushed on, and gradually the situation cleared. The 11th Inniskillings, for the final stage of the attack, had now moved in. This battalion met with somewhat stronger resistance. On the right some determined German bombers held up the advance for a while, the Lewis gunner not being able to see them. Here, as was generally the case, the Germans with their stick bombs outranged our men with the Mills, but the Mills rifle grenade more than restored the balance, and the Germans were driven steadily back. This company of the 11th Inniskillings was also able to give material assistance to the men of the 186th Brigade, across the Canal, by its Lewis-gun fire. Lock 6 was the last centre of strong resistance. Eventually the garrison fled across the Canal, though few of them reached the other side. About half-past three the Inniskillings crossed the Cambrai-Bapaume Road, and were soon afterward consolidating their position, with their outpost three or four hundred yards north of it. The bridge across the Canal here, it may be added, had been blown up hours earlier. It had never been doubted by the British that the enemy had prepared it for demolition.
