With the outbreak of the Revolution East Florida, remaining loyal to the British crown, was cut off from intercourse and trade with the rebellious colonies to the north and was victimized by privateers. The province could no longer import its food supplies from its neighbors, and cargoes of munitions, ordnance stores, and domestic goods from England were subject to capture at sea. By the same method St. Augustine sought to avenge and reimburse herself for her losses.
