Hill 70 was the first battle for the new Canadian Corps Commander, Lieutenant-General Arthur Currie, and tough test for the Corps after their victory at Vimy. The strategy used a three-stage advance, with very little time between each phase.

Lens, 21-25 August 1917

Despite the win at Hill 70, the Germans remained in the city of Lens. General Currie came under increasing pressure from High Command to attack the city, which he decided to do on 21 August 1917 on a narrow front.

Currie sent the 3rd and 4th Divisions into the city on 21 August, where they were halted in the maze of fortified houses and cellars. In an uncharacteristic decision, Currie decided to pivot to the Green Crassier on the outskirts of the city, sending in only one battalion – the 44th. The attack was called off on 25 August.
