A top-secret view of the German defences at Calais. This remarkable reproduction captures an original “Defence Overprint” map of Calais, created in 1944 to aid Canadian forces duri ng Operation Undergo — the assault on the heavily fortified port city guarding the French coast opposite Dover. The map reveals in extraordinary detail the German defensive network, including artillery batteries, anti-tank positions, minefields, and obstacles that made Calais one of the most formidable strongholds on the Channel coast. Used by planners and commanders of the Canadian 3rd Infantry Division, maps like this were critical for developing the precise attacks that ultimately forced the German surrender.
