Most Americans were totally unaware of the situation. Our government kept us in the dark for political reasons.
Even Germans were unaware. Hell, the commandants were, as well (till they were tortured into "awareness"). So was the Red Cross, who had an office in every camp. They never saw a gas chamber, other than the small ones used for clothing fumigation. So few knew any of it was going on. The high command must have gone to extraordinary lengths to hide it. The International Red Cross, immediately after the war, carefully figured the total death toll in all the camps combined to have been on the order of 300,000, of which a minority were Jewish, most having succumbed to typhus during the final months of the war. Boy, were they bamboozled.
