To the glory of God and to the memory of 11447 officers and men of the forces of the British Empire, who fell fighting in the years 1914–1918 between the River Douve and the towns of Estaires and Furnes, whose names are here recorded but to whom the fortune of war denied the known and honoured burial given to their comrades in death.[citation needed]
After Ploegsteert Wood (referred to colloquially as "Plug Street") had been the site of fierce fighting at the start of the war, it became a relatively quiet sector where no major action took place. Allied units were sent here to recuperate and retrain after fighting elsewhere and before returning to active operations. Berks Cemetery Extension was founded by Commonwealth troops in June 1916 as an extension to Hyde Park Corner (Royal Berks) Cemetery which lies across the road.[1] The cemetery grounds were assigned to the United Kingdom in perpetuity by King Albert I of Belgium in recognition of the sacrifices made by the British Empire in the defence and liberation of Belgium during the war.
The Ploegsteert Memorial lists over 11,000[5][6][7] missing Commonwealth soldiers from the following battles, which were fought outside the Ypres Salient in the area around Ploegsteert:[4]
Since 7 June 1999, the Comité du Memorial de Ploegsteert has arranged for the Last Post to be played at the memorial on the first Friday of each month.[9]
