The Pig War (1859) caused British and American forces to occupy opposing camps without fighting; 14 years of peaceful coexistence ended via 1872 Treaty of Washington. American Camp housed 62 U.S. Army soldiers; English Camp housed 83 British Royal Navy personnel. The conflict began when American farmer Griffin shot British pig Hudson, triggering mutual military deployment.
