9. Polish Resistance Against Nazi Soldiers, 1939: 2 Casualties, 12 Wounded
The Nazi invasion of Poland began on September 1, 1939. Jaslo, a Polish town close to the German border, became an essential site of the Polish resistance. One week into the invasion, on September 8, members of the opposition used mustard gas in an attempt to thwart the invading army.
The attack was less than successful, as only two people died. It did stir the ire of the Nazi military and was met with harsh reprisals. Polish political prisoners, including members of the resistance, became some of the first prisoners at Auschwitz.
