The Battle of Boca Teacapan was the result of a United States Navy expedition to destroy a Mexican pirate ship which was attacking targets in the Pacific Ocean. United States sailors and marines in several small boats pursued the pirates to the Boca Teacapan, in Sinaloa, and up the Teacapan Estuary for 42 mi (68 km) over several days in 1870 before defeating them at their hideout. The battle ended with the destruction of the pirate ship.
