History (Source: Wikipedia) 

The Battle of Mont Sorrel (Battle of Mount Sorrel, Battle of Hill 62) was a local operation in World War I by three divisions of the British Second Army and three divisions of the German 4th Army in the Ypres Salient, near Ypres, Belgium, from 2 to 13 June 1916.

To divert British resources from the build-up being observed on the Somme, the XIII (Royal Württemberg) Corps and the 117th Infantry Division attacked an arc of high ground defended by the Canadian Corps. The German forces captured the heights at Mount Sorrel and Tor Top, before entrenching on the far slope of the ridge. Following a number of attacks and counterattacks, two divisions of the Canadian Corps, supported by the 20th Light Division and Second Army siege and howitzer battery groups, recaptured the majority of their former positions.
