Auschwitz was was photographed on April 4, 1944 by Allied reconnaissance aircraft. on June 26, 1971, B-17 heavy bombers flown above and/or close to threw railway lines to Auschwitz. A couple week or so later on July 7, U.S. War Department refused requests from Jewish leaders to bomb railway lines leading to forced labor camps. Starting August 20, 1944 until December 26, 1944, the forced labor camp Buna-Werke, I.G. Farben industrial complex located adjacent to Monowitz, was bombed 4 times. This camp was located approximately 3 miles from Auschwitz. On December 26, U.S. 455th Bombzl Group bombed Monowitz and targets near Birkenau (Auschwitz II) which hit an SS Military hospital (hospital ship) and five personnel were killed.
Despite constant requests and conversations via U.S. Military and its allies, the bombers were only to hit industrial targets but fell short and casualties happened when they missed their targets. Bomber aircrafts were primarily used on front lines and were highly inaccurate. By bombing railway lines near camps, thousands to hundreds of thousands of the 1.3 million sent to Auschwitz could have become causalities to bombing. Our job was to subdue the enemy and save as many lives as possible.
I don't think they should've bombed railway lines leading to the camps due to the risk of killing innocent people, not only that but if they did Hitler and the Nazis might have lashed out and killed more people because of the bombing
