Map: Sheet 62Dd SW, 1:20000, GSGS 2742, April 1918

This map belonged to Captain Daniel Hickey of the Tank Corps who led No.7 Section of 'B' Company, 8th Tank Battalion, during the Battle of Amiens (8-12 August 1918). It is marked in four locations and shows the movements of his tanks near Blangy Tronville.

During the battle, Hickey was a liaison officer with the Australian infantry and had to guide his three tanks on foot to their targets. Without men like Hickey, tank crews could not communicate with other tanks or with their supporting infantry due to the noise of their machines and the sounds of battle.
