This image, which also comes from C. P. Stacey’s Official History of the Second World War, shows three maps that track the advancement of Canadian, British, and American troops into Normandy by June 13, July 24, and August 13 respectively.
The June 13th map (upper left-hand corner of the image) shows the coastline surrounding the Bay of the Seine. A solid green line represents the movement of United States troops inland towards the towns of Carentan and Caumont. Just east of Caumont, the
First Canadian Army (dotted red line) pushed inland and towards Caen.
The July 24th map (lower left corner of the image) shows the gradual advancement of the Allied troops from their initial positions on June 13th. The Americans expanded their southward advancement past Caretan to the west, but remained in roughly the same
position near Caumont. The Canadians mostly maintained their positions but advanced southward past Caen.
The final August 13th map (right side of the image) shows much more movement. The United States forces pushed further south. Green arrows branching off at different points shows expansion in all directions. The First Canadian Army pushed southwards towards
a German counter offensive (blue arrow) and were joined in northeastern sector by the Second British Army (solid red line).
The location of rivers and key towns are also labelled.
