The flank battalion was the 6th Connaughts with the 1st Munsters upon their left. Their objective was taken with a spring. The Munsters were able to consolidate at once. The Connaughts had more trouble as a rush of German bombers came down upon their right, driving the flank company in and forcing it back down the sap. For several hours there was hard fighting at this point, which was often hand-to-hand when the Irish bayonet men rushed at the German bomb-throwers. Finally a block and a defensive flank were formed, and two big Mebus, Mars and Jove, were left in the hands of the stormers. In the centre the advance of the 10th Dublin Fusiliers and of the 2nd Dublin Fusiliers was entirely successful. So sudden was the attack that many of the enemy were found wearing their gas masks. Two large Mebus, Juno and Minerva, with a good stretch of tunnel trench remained, together with many prisoners, in the hands of the stormers. The position was rapidly wired with concertina wire and new trenches dug for defence and communication by the {241} 155th Field Co. R.E. and the 11th Hants Pioneer battalion. On the left the storming battalions were the 2nd Royal Irish and the 7/8th Irish Fusiliers. The Royal Irish carried both tunnel and support trenches with the Flora Mebus, taking 200 prisoners. Many Germans retreated into the tunnel, but were pelted out again by Mills grenades. The Fusiliers were equally successful, but had one short hold-up owing to the determined resistance of a single officer and ten men. This little party made a brave fight, and were so situated that they commanded two lines of trench. Eventually they were all killed. The support trench was occupied, the tunnel cleared by the 174th Tunnelling Company, and the whole position made good in a most workmanlike way. A series of counter-attacks were stamped out by the barrage before they could get properly going. The tunnel, as explained, was a continuous gallery opening into the trench and extending eastwards. It had numerous chambers leading off, fitted with wire bunks, tables, etc. This section was elaborately mined, but the position of the leads had been accurately disclosed by a deserter, and they were soon cut by the sappers. In this swift and successful operation some 635 prisoners of the 470th and 471st Regiments were taken, with many minor trophies. Many Germans had been killed, 330 bodies being counted in the trenches alone. Altogether it was a remarkably smooth-running operation, and the model of an attack with limited objective, upon which General Haldane and all concerned might be congratulated. It was the more remarkable as it was carried out without {242} preliminary bombardment, and no help from the tanks.
