The Hohenzollern Redoubt was a strongpoint of the German 6th Army on the Western Front during the First World War, at Auchy-les-Mines near Loos-en-Gohelle in the Nord-Pas-de-Calais region of France. Named after the House of Hohenzollern, the redoubt was fought for by German and British forces. Engagements took place from the Battle of Loos (25 September – 14 October 1915) to the beginning of the Battle of the Somme on 1 July 1916, including the action of the Hohenzollern Redoubt in 1915 and the British Attack at the Hohenzollern Redoubt from 2 to 18 March 1916.
