4th battalion suffered 539 casualties (20 officers and 519 other ranks). While the commanders of the 2nd and 3rd battalions were both wounded, as was the Brigade commander, Brigadier General N.J.G. Cameron. The brigade's losses on 1 July were so severe that on the 6th, it, along with the 102nd (Tyneside Scottish) Brigade, was transferred to the 37th Division, swapping with the 112th Brigade. The two brigades returned to the 34th Division on 22 August. In February 1918 the 1st, 3rd and 4th Tyneside Irish battalions were disbanded and the remaining battalion, the 2nd, was transferred to the 116th Brigade of the 39th Division. From then on the Tyneside Irish Brigade ceased to exist and the brigade was simply the 103rd Brigade.
