The Battle of Jupiter Inlet was fought in Florida at Jupiter Inlet on January 15, 1838. A United States Navy led boat expedition to the Everglades was defeated by Seminole warriors in a small battle. It began when the expedition of 200 soldiers, sailors and marines under Lieutenant Levin M. Powell discovered a trail along the side of Jupiter Inlet. Fifty-five sailors and twenty-five marines and soldiers were landed to find the Seminoles who were encamped nearby under the command of medicine man Ar-pi-uck-i. When the Americans advanced on the Seminole camp, they were ambushed and after a long fight, they retired to their ten or so flat bottom boats unsuccessful. Five Americans were killed in action and another twenty-two others were wounded, Seminole casualties are unknown.
