Naval forces participated in the effort to forcibly move the Seminole Indians from Florida to a reservation west of the Mississippi. After a massacre of army soldiers near Tampa on December 28, 1835, marines and sailors were added to the forces which fought the Second Seminole War from 1836 until 1842. A "mosquito fleet" was formed in the Everglades out of various small craft to transport a mixture of army and navy personnel to pursue the Seminoles into the swamps. About 1,500 soldiers were killed during the conflict, some Seminoles agreed to move but a small group of Seminoles remained in control of the Everglades and the area around Lake Okeechobee.
