On July 12, 1915, Allied forces make a sixth and final attempt to capture Achi Baba, a prominent hill position featuring a commanding view of Cape Helles, on the Gallipoli Peninsula, from its Turkish defenders.
Though many modern-day historians have questioned the actual strategic importance of the hill in the grand scheme of the Gallipoli invasion, Achi Baba was seen by the Allied command at the time as a crucial objective in their struggle against the Ottoman Empire s forces and their German allies. Because of this, Sir Ian Hamilton, chief commander of the Mediterranean Expeditionary Force, had set the capture of Achi Baba as a priority from the first day of the Allied land invasion, on April 25, 1915. In addition to the disorderly landing itself, three separate unsuccessful attempts had been made to capture the heights, as well as the nearby village of Krithia, by that June. On June 28, another attempt met with similar failure, at the cost of heavy Allied casualties, in the Battle of Gulley Ravine.
The attack of July 12 began after the arrival of Sir Aylmer Hunter-Weston, a regional commander sent from the Western Front to aid Hamilton on the front lines in Gallipoli, along with an additional division of Allied forces. Yet again, the Allies were unsuccessful, gaining a total of only 350 yards over two days of heavy fighting before Hunter-Weston called off the attacks. The Allied casualty figure–4,000 dead or wounded–was lower than the Turkish one–some 10,000 men–but Achi Baba remained in Turkish hands. From then on, the bulk of Allied operations in Gallipoli were focused further north, around the so-called Anzac Cove (named for the Australia and New Zealand Army Corps) and Suvla Bay.
