English: map of Polish graves in Katyn, Russia, as "...part of a larger report, written between December 1944 and February 1946 by the Council of Ministers of the Polish Government in London, and entitled "Facts and Documents Concerning Polish Prisoners of War Captured by the U.S.S.R. During the 1939 Campaign". This report was transmitted by a member of the Polish government in exile, Lt. Gen. M. Kukiel, via the American military attaché's office in London, to Maj. Gen. Telford Taylor in December of 1947, and eventually appeared before the Madden Committee, having been mistaken for the lost "van Vliet report" (Record Group 319, Department of the Army, Office of the Assistant Chief of Staff for Intelligence, Permanent Retention Files, 1918-1963, 319-5937-1, Report - Facts and Documents Concerning Polish Prisoners of War Captured by the U.S.S.R. During the 1939 Campaign, 1946)."
