In suppressing the establishment at Amelia Island no unfriendliness was manifested toward Spain, because the post was taken from a force which had wrested it from her. The measure, it is true, was not adopted in concert with the Spanish Government or those in authority under it, because in transactions connected with the war in which Spain and the colonies are engaged it was thought proper in doing justice to the United States to maintain a strict impartiality toward both the belligerent parties without consulting or acting in concert with either. It gives me pleasure to state that the Governments of Buenos Ayres and Venezuela, whose names were assumed, have explicitly disclaimed all participation in those measures, and even the knowledge of them until communicated by this Government, and have also expressed their satisfaction that a course of proceedings had been suppressed which if justly imputable to them would dishonor their cause. In authorizing Major-General Jackson to enter Florida in pursuit of the Seminoles care was taken not to encroach on the rights of Spain. I regret to have to add that in executing this order facts were disclosed respecting the conduct of the officers of Spain in authority there in encouraging the war, furnishing munitions of war and other supplies to carry it on, and in other acts not less marked which evinced their participation in the hostile purposes of that combination and justified the confidence with which it inspired the savages that by those officers they would be protected. A conduct so incompatible with the friendly relations existing between the two countries, particularly with the positive obligation of the fifth article of the treaty of 1795, by which Spain was bound to restrain, even by force, those savages from acts of hostility against the United States, could not fail to excite surprise. The commanding general was convinced that he should fail in his object, that he should in effect accomplish nothing, if he did not deprive those savages of the resource on which they had calculated and of the protection on which they had relied in making the war. As all the documents relating to this occurrence will be laid before Congress, it is not necessary to enter into further detail respecting it. Although the reasons which induced Major-General Jackson to take these posts were duly appreciated, there was nevertheless no hesitation in deciding on the course which it became the Government to pursue. As there was reason to believe that the commanders of these posts had violated their instructions, there was no disposition to impute to their Government a conduct so unprovoked and hostile. An order was in consequence issued to the general in command there to deliver the posts--Pensacola unconditionally to any person duly authorized to receive it, and St. Marks, which is in the heart of the Indian country, on the arrival of a competent force to defend it against those savages and their associates.
