A crowd celebrates the arrival of Allied troops during a victory parade for the liberation of Paris, as suddenly shots from a sniper on one of the roofs are heard. Quickly the Parisians scatter for cover. Although the city was officially abandoned by the Germans, small bands of snipers remained active, which made the victory celebrations risky. 1944, August 29.
