Reserve units from the 4th Canadian Division came forward and once again attacked the German positions on the top of the ridge. Persistent attacks eventually forced the German troops holding the southwestern portion of Hill 145 to withdraw, but only after they had run out of ammunition, mortar rounds, and grenades. Towards midday, the 79th Reserve Division was ordered to recapture the portions of its third line lost during the progression of the Canadian attack. However, it was not until 6:00 pm that the force was able to organize and counterattack, clearing the Canadian Corps troops out of the ruined village of Vimy, but not recapturing the third line south of the village. By night time, the German forces holding the top of the ridge believed they had overcome the immediate crisis for the time being. Additional German reinforcements began arriving and by late evening portions of the 111th Infantry Division occupied the third line near Acheville and Arleux, with the remainder of the division arriving the following day.
