This U.S. Army photograph, once classified "top secret", is one of a series depicting the summary execution of 1,800 South Korean political prisoners by the South Korean military at Taejon, South Korea, over three days in July 1950. Historians and survivors claim South Korean troops executed many civilians behind frontlines as U.N. forces retreated before the North Korean army in mid-1950, on suspicion that they were communist sympathizers and might collaborate with the advancing enemy.
Sachsenhausen was a German concentration camp in Oranienburg (located 35 kilometres north of Berlin, Germany) used primarily for political prisoners from 1933 to the end of the Third Reich in May, 1945. After World War II, when Oranienburg was in the Soviet Occupation Zone, the structure was used as an NKVD special camp until 1950 (NKVD special camp Nr. 7). The remaining buildings and grounds are now open to the public as a museum.
