 As the Canadians began preparations for an assault, the Germans were in the process of executing an assault plan of their own.The XIII (Royal Württemberg) Corps spent six weeks planning and carefully preparing their attack on the Mount Sorrel, Tor Top (Hill 62) and Hill 61 peaks.Their objective was to take control of the observation positions east of Ypres and keep as many British units as possible pinned down in the area, to avoid them transferring to the Somme front and assisting with the observed build-up in that area.
