On April 19, 1943, the Warsaw Ghetto Uprising began with just 750 Jewish fighters — armed with pistols, a few rifles, and homemade grenades — against the full might of the SS and Wehrmacht. The uprising lasted until May 16. What German records documented and tried to suppress: the Jewish fighters held the Ghetto for nearly three weeks against forces that outnumbered them 20 to 1, destroying German tanks with gasoline bombs and killing an estimated 100-150 German soldiers. The Germans had to bring in flamethrowers and tanks specifically for urban combat. After the Ghetto was destroyed, the Germans deliberately bulldozed the area and planted trees to erase all evidence. A single SS officer, Captain Jürg, kept a private diary that included the line: "These people fought like Spartans. I will not speak of this again." His diary was found in 1958 in a Munich archive. It was never used in any war crimes trial.
