The Dade battle was an 1835 military defeat for the United States Army. The U.S. was attempting to force the Seminoles to move away from their land in Florida and relocate to Indian Territory. Amidst a war between the Government of the United States and the Seminole two U.S. Army companies numbering 103 men under the command of Major Francis L. Dade were ambushed by approximately 180 Seminole warriors as they marched from Fort Brooke on Tampa Bay to reinforce Fort King in Ocala. Only three U.S. soldiers survived the attack, and one died of his wounds the following day.

Francis Langhorne Dade was a Brevet Major in the U.S. 4th Infantry Regiment, United States Army, during the Second Seminole War. Dade was killed in a battle with Seminole Indians that came to be known as the "Dade Massacre".
