[Sidenote: _Battle of the Vineyard, August 6-7, 1915_] On August 6 the period of comparative inactivity came to an end. The primary purpose of the Gallipoli campaign was to obtain possession of the Narrows, and thus secure command of the Dardanelles and cut off communication with the Asiatic shore. It had been hoped to achieve this by pushing forward from the south, but the original force had been far too small for the purpose. During May, June and July the Turkish garrison had been much increased, and also the supply of guns and shells, and the defences on Achi Baba greatly and most ably strengthened, whereas the British reinforcements and drafts to fill the gaps had been relatively small. There was little prospect of success by a frontal assault from Helles, and the loss that would be incurred by a futile attempt would cripple the Allies and remove all chance of ultimate success. The Commander-in-Chief decided upon an attempt to reach the Narrows at Maidos, five miles across the peninsula from Anzac, the formidable Sari Bair range intervening. A new landing was to be made on August 6 and 7 at Suvla Bay, a few miles to the north of Anzac cove, and it was hoped that the force landed here would seize the northern slopes of the Sari Bair range, while the troops from Anzac would storm the central and southern heights. On August 6 an attack was to be made from the right of Anzac in order to divert attention from both the landing and the true objective; and a vigorous offensive was ordered at Helles, with the object of containing as large a Turkish force as possible within the southern area and of drawing their reserves from the north. There appeared to be good prospects of a decisive success, and hopes were high.
