When Jackson received these orders he was in Tennessee. He wrote immediately to the President: "Let it be signified to me through any channel (say Mr. J. Rhea) that the possession of the Floridas would be desirable to the United States and in sixty days it will be accomplished." General Jackson naturally supposed that this letter was duly received and read by President Monroe, and that a subsequent order, giving him discretionary powers in the prosecution of the campaign, contained the answer to it. As we shall see, however, the President claimed later that he did not read Jackson's letter until a year after it was written and sent to him. It was certainly {32} the President's fault if he did not. General Jackson certainly could not be held accountable for the President's strange negligence in examining official correspondence, and he had good reason to think, from the tone of the order issued to him after his letter had had due time to be received and read, that the Administration desired him to occupy Florida. Upon taking command Jackson called his Tennessee veterans to him, and reached with them the Florida frontier in March of 1818. [Sidenote: Jackson's operations in Florida.] When he advanced into Florida he found that the Spanish officials in Florida were in collusion with the Indians, and that the instigators of the hostilities were an Englishman, named Ambrister, and a Scotchman, named Arbuthnot, together with two Indian chiefs named Hillis Hajo and Himallemico. An order from the War Department, of January 16th, 1818, instructed the commander of the United States forces in Florida that the honor of the nation required a speedy termination of the War with the Seminoles, "with exemplary punishment for hostilities so unprovoked." Jackson naturally considered himself empowered to do speedy and thorough work. He felt it necessary to seize St. Mark's and Pensacola, in order to destroy the base of operations and the places of refuge of the enemy, and he caused the four ringleaders of the enemy to be executed. By the end of May (1818) the campaign was ended, and Florida was in the military possession of the United States. The President assumed the responsibility for Jackson's deeds, but offered to restore St. Mark's and Pensacola, and therewith the nominal possession of Florida, to Spain, so soon as Spain would garrison these points with forces able to maintain peace with the United States and {33} disposed to do so. Spain accepted the offer, fulfilled in a way the conditions, and the places were restored to her jurisdiction.
