Later in the campaign, Bassett was promoted to corporal. In August 1915, a series of offensives against Turkish positions along the Gallipoli front was planned to break the stalemate that had developed since the initial landing. On 7August, the New Zealand Infantry Brigade attacked Chunuk Bair, a prominent hill overlooking the battlefield. The battle lasted for three days. Chunuk Bair was captured by the brigade's Wellington Infantry Battalion on the second day, during which Bassett, in command of a section of five other signallers of his unit, laid down and maintained telephone lines between brigade headquarters and the front lines. Working on the exposed slopes leading up to Chunuk Bair, he braved continuous gunfire during this time armed with only a revolver and a bayonet. A bullet struck his boot and two more passed through the fabric of his tunic during the fighting, but he was not wounded.
