 Plugge's Plateau was located at the top of a steep 100 metre hill overlooking ANZAC Cove and Shrapnel Valley and was captured on 25 April 1915 shortly after the landing, by the 11th Battalion, 3rd Brigade of the AIF.The plateau was later named by the invading troops after 37-year-old Lieutenant Colonel Arthur Plugge commanding officer of the Auckland Infantry Battalion of the New Zealand Expeditionary Force, who established his headquarters there.It became a strongpoint within the ANZAC Inner Defence Line and the ANZAC headquarters were constructed lower down on the seaward side of the hill.
