The appearance of a North American squadron under John D. Henley and a land force under James Bankhead at the mouth of the St. Marys River on December 18, 1817, with orders to move against Luis Aury and his establishment on Amelia Island, compelled the filibusters to abandon posthaste their illfated Republic of the Floridas. Aury had occupied the island since September under the flag of Mexico. It was obvious that the North American fighting power was superior to any that Aury could muster and that surrender of the island was inevitable.
