100 years ago tank the first tank battle happened at Villers-Bretonneux.

The Second Battle of Villers-Bretonneux took
place from 24 to 25 April 1918, during the German Spring Offensive, against the Allied lines to the east of Amiens. It is notable for the first major use of tanks by the Germans, who deployed fourteen of their twenty A7Vs
and for the first tank-versus-tank battle in history. The tank battle
occurred when three advancing A7Vs met and engaged three British Mark IV tanks, two of which were female tanks armed only with machine-guns. The two Mark IV females were damaged and forced to withdraw but the male tank,
armed with 6-pounder guns, hit and disabled the lead A7V, which was
then abandoned by its crew. The Mark IV continued to fire on the two
remaining German A7Vs, which withdrew.
