1st Australian Casualty Clearing Station
Estaires is a town and commune in the Department of the Nord, about 11 kilometres west of Armentieres. The Estaires Communal Cemetery and Extension is on the eastern outskirts of the town and on the east side of the road to Bailleul. Estaires town was occupied by French cavalry on the 15 October 1914, and passed at once into British hands. On the 10 April 1918 it was captured by the enemy, after an obstinate defence by the 50th (Northumbrian) Division; and it was finally retaken by British troops at the beginning of September 1918.
Casualty Clearing Station
The town was a Field Ambulance centre as early as November 1914, and later the 1st Australian Casualty Clearing Station was posted in it.
