It was a bad position for the troops sent into action at that stage. The result of the battle on September 25th had been to create a salient thrust like a wedge into the German position and enfiladed by their guns. The sides of the salient ran sharply back--from Hulluch in the north, past the chalk-quarries to Givenchy, and in the south from the lower slopes of Hill 70 past the Double Crassier to Grenay. The orders given to the Guards were to straighten out this salient on the north by capturing the whole of Hill 70, Puits 14, to the north of it, and the chalk-pit still farther north. It was the 2d Brigade of Guards, including Grenadiers, Welsh and Scots Guards, which was to lead the assault, while the 1st Brigade on the left maintained a holding position and the 3d Brigade was in support, immediately behind. As soon as the Guards started to attack they were met by a heavy storm of gas-shells. This checked them for a time, as smoke-helmets--the old fashioned things of flannel which were afterward changed for the masks with nozzles--had to be served out, and already men were choking and gasping in the poisonous fumes. Among them was the colonel of the Grenadiers, whose command was taken over by the major. Soon the men advanced again, looking like devils, as, in artillery formation (small separate groups), they groped their way through the poisoned clouds. Shrapnel and high explosives burst over them and among them, and many men fell as they came within close range of the enemy's positions running from Hill 70 northward to the chalk-pit. The Irish Guards, supported by the Coldstreamers, advanced down the valley beyond Loos and gained the lower edge of Bois Hugo, near the chalk-pit, while the Scots Guards assaulted Puits 14 and the building in its group of houses known as the Keep. Another body of Guards, including Grenadiers and Welsh, attacked at the same time the lower slopes of Hill 70. Puits 14 itself was won by a party of Scots Guards, led by an officer named Captain Cuthbert, which engaged in hand-to-hand fighting, routing out the enemy from the houses. Some companies of the Grenadiers came to the support of their comrades in the Scots Guards, but suffered heavy losses themselves. A platoon under a young lieutenant named Ayres Ritchie reached the Puits, and, storming their way into the Keep, knocked out a machine-gun, mounted on the second floor, by a desperate bombing attack. The officer held on in a most dauntless way to the position, until almost every man was either killed or wounded, unable to receive support, owing to the enfilade fire of the German machine-guns.
