The US broke truce flags and used bloodhounds against the Seminoles

Evidence

In 1837, 33 Seminole leaders, including Osceola, were captured while negotiating under a flag of truce. Osceola later died in captivity, succumbing to complications from malaria. The U.S. Army imported bloodhounds from Cuba in an unsuccessful attempt to track the remaining Seminoles. Even without the dogs, the odds were heavily against the Seminoles. Fifty thousand federal soldiers served in the Second Seminole War, and there were never fewer than 3,800 soldiers in the field at any one time. The Seminoles, by contrast, had no more than 1,500 warriors total. — Winona LaDuke, All Our Relations, 161
