Some of the first deaths during the American landings in Africa where caused by the Vichy French. The Americans notified them ahead of time of the landings and some towns set up ambushes. They also bombed the Straits of Gibraltar, the Allies HQ.

While everyone agreed WW2 would not be a gas war like WW1, both sides were prepared since nobody trusted anybody. While it is believed no gas was during the war, there was in fact one battle where gas artillery was used... by the Americans! Somebody in an artillery battery grabbed the wrong shells and they fired a few gas rounds at the Germans. Upon realizing what they did the Americans called a "time out" during the battle and radioed the Germans to apologize and offer medical aid.
