Courtney's Post was the centre post of three - Quinn's, Courtney's and Steele's - that occupied precarious, but critical, positions along the lip of Monash Valley, in the heights above ANZAC Cove. Monash Valley ran right into the heart of the ANZAC position and, as Shrapnel Valley, continued on down to the beach at ANZAC Cove. The post was named after Lieutenant Colonel Richard Courtney, commander of the 14th Battalion, which had occupied the position on 27 April 1915. The position had been originally captured by men of the 11th Battalion on the morning of 25 April.
Courtney's Post was the scene of particularly ferocious fighting during the Turkish attack of 19 May and it was for his actions to oust the enemy from part of the post that Private Albert Jacka was awarded the Victoria Cross.
