Such was the task of the 29th Division, their general objective being the low but formidable position of Achi Baba, a hill sitting asquat almost across the Peninsula about five miles from Cape Helles, and rising by gradual and bare slopes to a truncated pyramid, some 600 to 700 feet high. About nine miles along the coast beyond Y Beach, between a point north of Gaba Tepe and a slight projection then called Fisherman’s Hut, three miles farther up the coast from Gaba Tepe, the Anzacs were to land on Z Beach, and work their way into the defiles and up the heights of Sari Bair. Their main purpose was to distract the enemy forces south of Achi Baba by threatening their rear and communications. With a similar object the greater part of the Royal Naval Division, which had no guns, and for which no small boats could be supplied, was to make a feint near the Bulair lines at the head of the Gulf. Further to distract the enemy’s attention, one infantry regiment and one battery from the French mixed Division were instructed to land on the Asiatic shore near Kum Kali; but not to remain there, nor advance beyond the river Mendere. Such, in brief, was the general design for attacking the Peninsula position, confidently described by German authorities as impregnable. By the middle of April the force appointed to accomplish this overwhelming task had assembled in the Mudros harbour or loch. Large as that inlet is, the surface was so crowded with ships that the naval authorities, among whom Commodore Roger Keyes was Chief of Staff to Admiral de Robeck, had difficulty in finding anchorage for all. Beside the ships of war, places had to be fixed for 108 transports and other vessels. The 29th Division had arrived in twenty transports;[82] the Anzacs in forty; the Royal Naval Division in twelve; the French Division in twenty-three; the Supply and Store Ships numbered twelve, and the _Arcadian_ was detailed for General Headquarters.
