The Battle of St. George's Caye was a military engagement that lasted from 3 to 10 September 1798, off the coast of British Honduras (present-day Belize). However, the name is typically reserved for the final battle that occurred on 10 September in which the Spanish were defeated. The events of 10 September 1798 marked the final Spanish attempt to take over the area. In Belize, the Battle of St. George's Caye is a national public and bank holiday.
