At 5:30 a.m. the Canadian Corps launches its attack against Vimy Ridge as part of the larger Arras offensive. The commanding position atop the ridge is to serve as a hinge for further British operations in the coming weeks. This is the first occasion when all four Canadian divisions operate as a complete corps. The Germans are deluged with accurate artillery, mortar and machine-gun fire as the Canadians advance in the midst of driving wind, snow and sleet. On the left flank of the Canadian attack, 4th Division is charged with the capture of Hill 145. Third and 2nd divisions attack in the centre of the ridge, while 1st Div. advances on the right. The entire ridge is secured on April 12 with the capture of the Pimple, a high-terrain feature near Hill 145. The Canadian Corps suffers more than 10,500 casualties, including more than 3,500 killed. Four Canadians are awarded the Victoria Cross for their roles in the battle, and many Canadians see the victory as a crucial turning point in Canada’s march to nationhood.
