The Second Seminole War, the second of three wars between the United States government and the Seminoles, grew out of the Treaty of Payne's Landing in 1832, which required the Seminoles to leave Florida; when they refused, war followed. In 1836, Camp Monroe was established as the East Florida headquarters for the US Army on the southern shore of Lake Monroe on the St. Johns River. On February 8, 1837, Seminoles led by Coacoochee attacked Camp Monroe, Captain Charles Mellon was killed, and on February 11 the camp was renamed Fort Mellon. The war continued until 1845 at a cost of millions of dollars and thousands of lives, forcing many Seminoles to leave Florida for lands west of the Mississippi River, while others hid in the Everglades and later fought again in the Third Seminole War in 1855. Osceola, born in Alabama in 1804 and brought to Florida at an early age, was never a Seminole chief but became a fierce leader with many followers whose main encampment stood on the southern shore of Lake Monroe; after leading many battles against U.S. soldiers in resistance to removal, he was captured under a white flag of truce in October 1837, taken to Fort Moultrie in South Carolina, and died there in January 1838. Coacoochee, also known as Wild Cat, was born in 1810 in Mosquito County, now Seminole County, to a sister of Micanopy and King Philip; he and King Philip led the attack on Camp Monroe, became the most respected war chief after Osceola's death, was captured several times and escaped, then after another capture in October 1841 was sent to a reservation in the Arkansas Territory, now Oklahoma. In 1845 he was taken to Texas for a peace mission, but instead traveled through Texas for four years inciting hostile Indians, recruited Kickapoo warriors, and with Seminoles and Blacks escaped into Mexico, where he died of smallpox in 1857. Fort Mellon stood on Lake Monroe at the foot of the US Army road now called Mellonville Avenue and remained there until after the Civil War, when the town of Mellonville grew around the site; in 1837 it was sketched by Captain John Rogers Vinton of the US Army Third Artillery. The US Army Second Regiment of Dragoons was stationed at Fort Mellon from 1837 through 1841, and the palmetto leaf on its unit insignia represents the Second Seminole War.
