Cross of the Warsaw Uprising

The Cross of the Warsaw Uprising (Polish: Krzyż Powstania Warszawskiego) was an informal award used by soldiers of the Polish resistance during the Warsaw Uprising of 1944. It consisted of a captured German Iron Cross, with a pre-war 1 złoty coin pinned to it in the centre over the swastika; the reverse side of the coin, showing the Polish eagle, was displayed, to which was added a kotwica and the inscription "1944".
