In September 1856, Brigadier General William S. Harney returned to Florida as commander of the federal troops. Remembering the lessons he had learned in the Second Seminole War, he set up a system of forts in a line across Florida, and patrols moved deep into Seminole territory. He planned to confine the Seminoles to the Big Cypress Swamp and the Everglades, because he believed they would be unable to live there during the wet season. He anticipated being able to catch the Indians when they left their flooded sanctuaries seeking dry land for raising their crops. Part of Harney's plan involved using boats to reach islands and other dry spots in the swamps. He first made one more attempt to negotiate with the Seminoles but was unable to make contact with them. In early January 1857, he ordered his troops to actively pursue the Indians. Harney's plan, however, had shown few results by the time he and the Fifth Infantry were transferred to Kansas to aid in the uprisings there in April.
