The VIII Corps front was intersected by two deep ravines respectively called Gully Ravine, near the Ægean coast, and Krithia Nullah on the immediate left of the Krithia Road, and both of these, originating in the slopes of Achi Baba, formed deep furrows through the British lines, running towards the sea in a direction roughly parallel to the Krithia Road. The high ground between the ravines formed a plateau covered with scrub and gorse, and intersected in all directions by water courses of less importance; the whole area being uncomfortably exposed to direct observation from the Turkish defences on Achi Baba. All along this front the British and Turkish lines were close together—in some places only about 30 yards apart—and a continual and deadly warfare, in which bombs played a prominent part, was being waged from sapheads pushed out from the main defensive positions and held by barricades.

The Royal Naval Division's subsector included several of such centres of activity, notably at the Northern and Southern Barricades, on the left, and at Worcester Barricade, a sap pushed forward from the Rue de Paris, in the centre.

The exposure of the whole British area to observation rendered necessary the use of very long communication trenches, to afford cover to the mule transport whereby the trench garrisons were supplied with rations and trench stores. These wide mule tracks, doubled for upward and downward traffic, were carried forward from the crest of the plateau above the beaches at Cape Helles to within a few hundred yards of the front trenches.

On the 20th October the 1st R.N. Brigade relieved the 2nd Brigade in the centre subsection, the forward system of trenches being occupied by "Drake," "Nelson," "Hood" and "Hawke," the 2/4th Londons relieving the 2/2nd Londons in the Eski line, a reserve line some 1500 yards in rear of the most advanced trenches. The Battalion occupied this line with two companies each side of the Eastern Mule Trench. The relief was carried out without difficulty, but during the move forward from bivouacs the Battalion incurred its first battle casualties, Capt. H. Morris and Privates Housden and Maunder being wounded.

At this time the Turkish Feast of Barram was proceeding, and when it drew to a close on the evening of the 22nd it was anticipated with some confidence that the enemy would attempt a demonstration against the Allied positions. The only activity, however, was on our side and our batteries both on land and sea gave the Turks a particularly hot time during the evening. During this tour the weather began to break and heavy rains fell, but apart from the wet condition of the trenches and the consequent additional work in keeping them in repair the tour of duty passed without incident of an unusual nature. On the 22nd half the company officers and non-commissioned officers were attached for instruction in the front line to the R.N. Battalions, their places being taken after forty-eight hours by the other half.

On the 27th the 2nd Brigade returned to the line relieving the 1st Brigade, which withdrew on relief to the Rest Camp, the 2/4th Londons handing over their positions in the Eski line to the 2/2nd Londons.

This day General Sir Ian Hamilton handed over command-in-chief of the Dardanelles Army to General Sir C. C. Monro, K.C.B. Sir Charles Monro's duty on assuming command was in the first instance to report as to the desirability, on purely military grounds, of evacuating the Peninsula, and alternatively as to the force required to bring the campaign to a successful issue. A reconnaissance of the position led him to the conclusion that evacuation should be taken in hand, and the adoption of this course received official approval, with results which will be recorded in their place.

In the Rest Camp the Battalion spent six days, which were occupied in work on new winter quarters and dugouts, and which passed quietly but for heavy shelling on the 29th October and the 1st November from enemy batteries on the Asiatic shore; but fortunately no casualties were suffered.

The month of November was occupied in duty in and out of the line, tours in the trenches being for seven days, followed by seven days in the Rest Camp at Cape Helles. For both the tours in line the 2/4th Londons were in reserve in the Eski lines though on each occasion companies were sent in turn to the front trenches for instruction in trench warfare. For this purpose they were attached to "Hawke," "Hood" and "Drake" Battalions.
