On August 19, 1944, the French Résistance in Paris launched an open uprising against German occupation — the beginning of a week-long liberation that ended on August 25 with the surrender of General Dietrich von Choltitz. In the first hours of the uprising, there were numerous spontaneous arrests of alleged collaborators by civilians and police forces on the streets of the city. Jack Lieb captured such scenes with his 16mm Kodachrome camera, documenting in color events from these days that are otherwise almost exclusively preserved in black and white.
