The attack upon this central height was to have been made before dawn. It was late. Under increasing daylight, shrapnel began to spit and shower overhead, striking with cross-fire from Battleship Hill and a position on the left crest of Chunuk. The men were much exhausted. They had accomplished a night march of extreme difficulty, exposed to continuous perils and surprises. Nevertheless, the united battalions struggled forward up the ridge, rough with every obstacle and rising with a steep gradient. After a toilsome climb, at 8 a.m. they reached a point (almost at once called the Mustard Plaster, but afterwards known as the Apex) where a depression in the ridge afforded some slight cover from the guns, and there they hurriedly entrenched a position. On the left it hangs above the Farm, upon which the farthest end of it looks steeply down. A narrow but uninterrupted Nek of some 400 or 500 yards (roughly a quarter-mile) extends the ridge to the sky-line summit--the right or southern shoulder of Chunuk Bair. [Sidenote: THE ASMA DERE AND THE FARM] Meantime, on the previous evening, the Left Covering Force (Brigadier-General Travers) had followed so closely upon the heels of the Right Covering Force along the shore that they had to pass through them at the mouth of Chailak Dere. When clear, they proceeded straight forward along the level to Aghyl Dere, though exposed to desultory fire from Bauchop’s Hill, not yet fully occupied. Turning sharply up the Dere, they emerged from it to the left and seized the entrenchments on the confused heights of Damakjelik Bair with so impetuous a rush that some Turkish officers were caught in the unsuspecting security of pyjamas. In this attack the 4th South Wales Borderers (under Lieut.-Colonel F. M. Gillespie, an exceptionally fine officer) especially distinguished themselves, and by 1.30 a.m. the position was securely held. The force was thus able to cover the advance of the assaulting column up the Aghyl Dere, and to come into touch with the Suvla landing farther north.
