Hessians were German soldiers who served as auxiliaries to the British Army during several major wars in the 18th century including the American Revolutionary War. The term is a synecdoche for all Germans who fought on the British side, since 65% came from the German states of Hesse-Kassel and Hesse-Hanau. Known for their discipline and martial prowess, around 30,000 Germans fought for the British during the war, around 25% of British land forces.
