Battle of Vimy Ridge order of battle

Canadian Corps commander Lieutenant-General Sir Julian Byng had four attacking divisions, one division of reserves and numerous support units under his command. He was supported to the north by the 24th British Division of I Corps which advanced north of the Souchez river and by the advancing XVII Corps to the south.[7] The 4th Canadian Division was responsible for the northern portion of the advance which included the capture of the highest point of the ridge followed by the heavily defended knoll known as "the Pimple" just north of the town of Givenchy-en-Gohelle.[7] The 3rd Canadian Division was responsible for the narrow central section of the ridge, including the capture of La Folie Farm. The 2nd Canadian Division, which later included an additional brigade from the 5th British Division was directly south of 3rd Canadian Division and entrusted with the capture of the town of Thélus.[7] The 1st Canadian Division was responsible for the broad southern sector of the corps advance and was expected to make the greatest advance in terms distance. Byng also planned for a healthy reserve for contingencies in case additional troops were needed to relieve forward troops, help in consolidating positions or aiding the 4th Canadian Division with the capture of "the Pimple". As a result, the 9th Canadian Brigade, 15th British Brigade and 95th British Brigade were kept in a corps-level reserve.[7]

German Sixth Army commander General Ludwig von Falkenhausen had 20 divisions (plus reserves) responsible for the Cambrai–Lille sector.[8] Vimy Ridge itself was principally defended by the ad hoc Gruppe Vimy formation under the I Bavarian Reserve Corps commander General der Infanterie Karl von Fasbender.[9] A division of Gruppe Souchez, under the VIII Reserve Corps commander General Georg Karl Wichura, was also involved in the front-line defence along the northernmost portion of the ridge.[10]

Three divisions were ultimately responsible for manning the front-line defences opposite the Canadian Corps. The 16th Bavarian Infantry Division was located opposite the town of Souchez and responsible for the defence of the northernmost section of the ridge. The division had been created in January 1917 from existing Bavarian formations and had so far only opposed the Canadian Corps.[8] The 79th Reserve Division was responsible for the defence of the central section, including the highest point of the ridge, Hill 145.[11] The 79th Reserve Division had fought for two years on the Eastern Front and was 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 was holding the villages of Thélus, Bailleul and the southern slope of the ridge.[8]
