Between January 1942 and June 1944, over 300,000 members of the United States Military passed through Northern Ireland. For the most part, relations between the Americans and locals were good. However, over that time, members of the United States Military were responsible for 7 deaths.
Among the dead were 5 civilians, a British soldier, and an American soldier. In a total of 5 of the cases, drunkenness played a role as troops took leave and socialised in towns and villages.
American troops committed other crimes such as vandalism and assault. They were also sometimes the victims of attacks from British service personnel. As Northern Ireland was the first place in Europe to host the United States Military, it led the way in how the United Kingdom would deal with later cases.
