Bahia incident

The Bahia incident was a naval skirmish fought in late 1864 during the American Civil War. A Confederate States Navy warship was captured by a Union warship in Bahia Harbor, Brazil. The engagement resulted in a United States victory, but also sparked an incident with the Brazilian government, which claimed the Americans had violated Brazil's neutrality by illegally attacking a vessel in their harbor.
