This met the same fate. Meanwhile the men of the Ulster Division were fighting just as desperately. They had ahead of them several of the concrete forts, one of which, near Pond Farm, was a strong defensive system with deep dug-outs and overhead cover proof against shell-fire. This and other strong points had wooden platforms above the concrete walls, on which the gunners could mount their machines very quickly, firing them behind two yards thickness of concrete. Opposite the Pommern Redoubt stands a small hill which the enemy has used for a long time as one of his chief observation-posts, as it gives a complete view of our ground. Beyond that the country rises to a saddle-back ridge, with double spurs guarded on the lower slope by a small fort called Gallipoli, and from these spurs he could fling a machine-gun barrage across the low ground. An ugly position to attack. It was worse for the Ulster men because of the state of the ground, which was a thin crust over a bog of mud. On the left some of the Inniskillings and Irish Rifles rushed forward as far as a network of trenches and wired defences, which they took in a fierce assault against a Bavarian garrison, who fought to a finish. Here they recaptured one of our Lewis guns lost in the fighting on July 31. On the right the Irish Rifles and the Fusiliers, walking through the fire of many machine-guns, made a straight attack upon Hill 35, which dominated the centre of the Ulster attack. Before it were some gun-pits, and the Ulster men, by most desperate efforts, took and crossed these pits and fought up the slopes of the hill beyond. But they could not keep the hill nor the pits. So after many hours of frightful fighting the situation was that some scattered groups of Dublins and Royal Irish held out on a far goal with exposed flanks, with some Inniskillings clinging to the slopes of Hill 37, while on the other side of the Zonnebeke river the Ulster men had been forced off their little hill, and had been unable to get beyond the German chain of concrete houses. The enemy's aeroplanes came over to survey the situation, and, taking a leaf from our book, flew very low, firing their machine-guns at the advanced posts of Irish lying in shell-holes and in the hummocky ground. They were in a desperate position, those advanced posts.... Then the enemy launched his counter-attack from the direction of Zonnebeke, and gradually the shattered lines of the Irish fell back, slowly fighting little rear-guard actions in isolated groups. Many of them were surrounded and cut off, or had to fight their way back in the night or the dawn of next day.
