MacGregor conquered Amelia Island, the only territory the country consisted of, and raised the Green Cross of Florida flag over the Spanish Fort San Carlos.Many citizens and politicians in the United States feared this haven and wished to bring Florida under control in order to protect the southern border.[8] In early February 1817, MacGregor arrived in Baltimore, Maryland, and began to gather political and financial support to “wrest Florida from Spain” and embolden “the existing disposition of the people in that section to confederate with the United States” until a more “favorable time for their admission into the Union.”[9][10] He intended to use a private force so that the United States could add Florida to its holdings while avoiding responsibility for an invasion.Before taking his small force down into the Florida territory, MacGregor sent an agent in disguise to sow fear amongst the citizens of Amelia Island and the garrison at Fort San Carlos.Shortly after the second failed attack by the Spanish, a French-born pirate named Louis-Michel Aury arrived and assumed military command, making Hubbard his adjutant-general.Aside from a growing mountain of issues on Amelia Island itself, the United States government was also becoming increasingly unhappy about the smuggling and privateering of the "Republicans of the Floridas."[17]"It also shews that the Pseudo-Patriots of Fernandina were one day Americans and the next Fioridians that there were to be found among them natives or subjects of all nations except Spain or Spanish America and that their true and sole object was booty.
