For a long time a portion of the enemy's trench was held by mixed units, but it was of no value when detached from the rest and was abandoned in the evening. From the afternoon onwards no possible course save defence was open to General Lambton. There was considerable anxiety about one company of Irish Fusiliers who were in a detached portion of the German trench, but they succeeded in getting back next morning, bringing with them not only their wounded but some prisoners. Immediately to the right of the Fourth Division was the Twenty-ninth Division[1] from Gallipoli, which rivalled in its constancy and exceeded in its losses its comrades upon the left. The 86th Brigade and the 87th formed the first line, with the 88th in support. [1] Since the constituents of this famous regular Division have not been given in full (as has been done with their comrades in preceding volumes) they are here enumerated as they were on July 1, 1916: 86_th Brigade_.--2nd Royal Fusiliers, 1st Lancashire Fusiliers, 1st Dublin Fusiliers, 16th Middlesex. 87_th Brigade_.--1st Inniskilling Fusiliers, 1st South Wales Borderers, 1st Scottish Borderers, 1st Border Regiment. 88_th Brigade_.--1st Essex, 2nd Hants, 4th Worcesters, Newfoundland Regiment. The van of the attack upon the right of the division was formed by the 1st Inniskilling Fusiliers and the Welsh Borderers, while the van upon the left was formed by the 2nd Royal Fusiliers and the 1st Lancashire Fusiliers. The other battalions of the {54} brigades formed the supporting line, and two battalions of the 88th Brigade, the Essex and the Newfoundlanders, were also drawn into the fight, so that, as in the Fourth Division, only two battalions remained intact at the close, the nucleus upon which in each case a new division had to be formed. Upon the explosion of the great mine already mentioned two platoons of the 2nd Royal Fusiliers with machine-guns and Stokes mortars rushed forward to seize the crater. They got the near lip, but the enemy were already in possession of the far side, and no farther advance could be made. At this point, and indeed at nearly all points down the line, the wire was found to have been very thoroughly cut by the artillery fire, but for some reason our own wire had not been cut to the same extent and was a serious obstacle to our own advance.
