By this time two brigades of the 52nd Division had arrived, and the third was nearly due. It was a Territorial Division (the “Lowland”), commanded for the first few months by Major-General G. G. A. Egerton. After the fighting of July 12 and 13, he was ordered to a hospital ship owing to natural fatigue; but returning next day, he retained command till mid-September, when he was succeeded by Major-General H. A. Lawrence, son of the great Lord Lawrence of the Indian Mutiny.[131] It was a fairly homogeneous and steady division, and, though rapidly reduced in strength, its improvement after the first month or six weeks was much remarked. [Sidenote: SHORTAGE OF ARTILLERY] It was not long before one of the newly arrived brigades was called into action. The artillery, even with French help, was now insufficient for another general advance. The shells were running out; few H.E. shells were left; the howitzers numbered eight, or two to a division (four others which arrived later had seen service at Omdurman in 1898); whereas, even at the beginning of the war, eighteen howitzers went to each division in France. Among the field-guns were batteries of old 15-pounders, which had established their futility in the Boer War (one Vickers gun was reported to have come from a well-known museum); but such things were thought good enough for the Dardanelles. Except the 29th and the Anzacs, the Divisions had no other field-guns, and the R.N.D. had no guns at all. It was, therefore, essential to limit the thrust, and General Hunter-Weston formed a scheme for pushing forward on the left, so as to clear the obstacles which had hitherto checked our advance along the coast, and to reduce the salient in the centre, as the French had reduced it by seizing the “Haricot.” While the centre remained steady about a mile from the sea, the left was to swing forward upon it as upon a pivot, covering less ground as the pivotal point was approached. Thus five Turkish lines had to be captured by the 29th Division on the extreme left, and two by the 156th Brigade (52nd Division), which had been inserted on their right. [Sidenote: THE GULLY RAVINE]
