On 1 August 1944, the Warsaw Uprising against the Nazi occupation of Poland began. Hundreds of thousands of people died during the fighting and Poland's capital was almost completely destroyed. Among the underground fighters were children, many of them members of the Scout movement. Andrzej Slawinsky was one of them. (Photo: Insurgents on the streets of Warsaw, 1944.
