Recherche dans la collection - Sub-series 3.6: Lens (including Hill 70 and Avion) April 1917 - May 1918 [cartographic material]

Following the victory at Vimy, the Canadian Corps was placed under the leadership of Lieut.-General Sir Arthur Currie and was directed to mount attacks on Lens beginning in late April. The assault was necessary in order to keep the Germans occupied and away from the major offensive that the Allies had begun in Flanders. Currie's plan was to encircle the city by taking the small town of Avion to the southeast of Lens and Hill 70 to the north. By late August, both operations had been declared entirely successful, despite intense German counterattacks, especially on Hill 70.
As evident from the following list, the Canadian Corps produced a large number of maps in support of their assault on Lens, especially trench maps. In order to assist researchers in their searches, the items listed under trench maps have been subdivided into the two major campaigns: Hill 70 and Avion.
