James Horan’s biography of Itcho-Tustinnugee:

“In the fall of 1823, two years after Florida came into the possession of the United States, a treaty was signed by three Indian commissioners from Washington with the Florida tribes. . . . The Seminole were outraged when they discovered that they were now confined within certain boundaries, whereas in the past they had roamed and hunted where they pleased. . . . It took two more years, but in 1826 more land was given to the Seminole. Then the United States followed its classic pattern in dealing with Indian nations: in 1832, a small group of chiefs was persuaded to sign the Payne's Landing Treaty, thus yielding up to the United States the very lands given to them by the government. . . . The Seminole War broke out after Osceola denounced the chiefs and warned that anyone who sold Seminole land would die. ‘Itcho means deer and Tustennuggee, warrior, so he is therefore known by the English name of Deer Warrior,’ McKenney wrote in 1835. ‘He was doubtless famous when young for killing deer, and no doubt owes his name to killing deer. He is a partisan chief. One who hunts of choice, but fights when he is called upon to do so.’”
