In the weeks before D-Day on June 6, 1944, southern England had become the largest staging area in history. Roads, ports, and countryside were controlled by Allied troops to ensure strict secrecy of invasion preparations. Control posts like this one—identifiable by a British road sign and the marking TP 332—secured military traffic and regulated freedom of movement in the sealed coastal zones. Jack Lieb captured this preparation phase in color before he himself embarked with the 82nd Airborne Division to France.
