Jack Lieb filmed in London in May 1944 while the Allied forces were preparing for the invasion of Normandy. The Marble Arch – originally erected in 1827 as an entrance gate to Buckingham Palace, relocated to the northern edge of Hyde Park since 1851 – was a well-known landmark in wartime London. The footage belongs to the opening sequence of Lieb’s film, which documents life in the British capital in the weeks immediately before D-Day (June 6, 1944). As a rare color document, it shows the civilian and military everyday life of London shortly before the start of the largest amphibious operation of the Second World War.
