Battlefield of La Coulotte, France, 1917 After the successful attack on Vimy Ridge by the Canadian Corps, eastward movement by the Canadians slowed down immensely during the next few weeks. The troops were exhausted and were facing another line of prepared German positions. Much of the Corps’ supporting artillery was withdrawn to join British operations to the north. Nonetheless, by May the officers and men of 1st (British) Corps and the Canadian Corps had been ordered to concentrate against enemy positions in the area of the Souchez River in an attempt to break the German defensive line between the village of Avion, south of the city of Lens, and the western portion of Lens itself. The 4th Canadian Division, on the left of the Canadian Corps’ front, was ordered to capture the village of la Coulotte, an electrical generating station, and a brewery in the area between Avion and the Souchez River. Attacks by the division in late May and early June drew repeated German counterattacks that were broken up by Canadian artillery and small arms fire.
