Three divisions were ultimately responsible for manning the frontline defences opposite the Canadian Corps. The 16th Bavarian Division was located opposite the village of Souchez and responsible for the defence of the northernmost section of the ridge. The division had been created in January 1917 by amalgamating existing Bavarian formations and had so far only opposed the Canadian Corps. The 79th Reserve Division was responsible for the defence of the vast central section, including the highest point of the ridge, Hill 145. The 79th Reserve Division had fought for two years on the Eastern Front before being transferred to the Vimy sector at the end of February 1917. The 1st Bavarian Reserve Division had been in the Arras area since October 1914 and held the villages of Thélus, Bailleul and the southern slope of the ridge.
