The Polish government-in-exile in London first reported the gassing of prisoners in Auschwitz on 21 July 1942, and reported the gassing of Soviet POWs and Jews on 4 September 1942. In 1943, the "Kampfgruppe Auschwitz" (Combat Group Auschwitz) was organized within the camp with the aim of sending out information about what was happening. The "Sonderkommando" buried notes in the ground, hoping they would be found by the camp's liberators. The group also smuggled out photographs; the "Sonderkommando" photographs, of events around the gas chambers in Auschwitz II, were smuggled out of the camp in September 1944 in a toothpaste tube.
