Treblinka extermination camp

"Just as we went by, they were opening the gas-chamber doors, and people fell out like potatoes. ... Each day one hundred Jews were chosen to drag the corpses to the mass graves. In the evening the Ukrainians drove those Jews into the gas chambers or shot them. Every day! ... More people kept coming, always more, whom we hadn't the facilities to kill. ... The gas chambers couldn't handle the load."
