It was held by a variety of units until the evacuation of the Anzac sector and was the site of continual attacks and hand-to-hand fighting as Turkish troops defending the peninsula strove to recapture it.
Fighting was intense, with heavy casualties on both sides, as it was a key position at the end of the Anzac line.
Periscopes were used to survey the surrounding area, although they were prone to being damaged by rifle fire, and periscope rifles eventually allowed accurate fire to be directed towards the Turkish trenches.
It was named after Major Hugh Quinn, the 27-year-old commander of C Company, 15th Battalion, Australian Imperial Force.
Quinn was killed there on 29 May whilst reconnoitring for an attack to recapture trenches seized by the Turks earlier in the day and is buried in Shrapnel Valley Cemetery.
