Brooks: Diplomacy and the Borderlands The hostility of other whites in Florida, particularly the agents of John Forbes and Company, also worked to his disadvantage. He was sentenced to be hanged. Ambrister plead guilty of leading the Indians in war against the United States, and was sentenced to be shot. In Ambrister's case, which has been considered the more definite, one of the officers sitting on the court-martial reconsidered his vote, which changed the sentence from death to fifty lashes. Jackson, who approved of both original sentences, discountenanced the reconsideration. On April 29, Ambrister was shot and Arbuthnot was hanged. Not wishing to return to the United States, and having heard that a body of Indians had gathered at Pensacola, some 275 miles away, Jackson marched westward from St. Marks. He accused the Spanish governor at Pensacola of having aided the Indians, and demanded the surrender of the town. The basis for his accusation was so weak that the venture had best be explained as simply a part of his plan for seizing the provinces, and holding them for indemnity." Whatever the real motive, on May 24 he occupied Pensacola, and three days later Fort Barrancas, to which the gov- ernor and garrison had fled, and which they defended briskly but briefly. The Spaniards were allowed to go to Havana, and a guard of United States troops was left in charge of the fort. Jackson had meanwhile ordered General Gaines to seize St. Augustine, but such a drastic step was discountenanced by the War Department and the orders were revoked. The general then retired to his home in Tennessee, leaving the diplomats with an embarrassing faith accompli. Onis' sojourn at Bristol was disturbed, as has been explained, by increasingly dire reports from the Floridas. While he awaited their confirmation, he received the instructions of April 6 and April 25, the latter of which gave him his first authority to place the boundary limit as far west as the Sabine. From this date it was the constant effort of both Onis and Adams to push the negotiation as fast as propriety would permit, in the hope of bringing their diplomatic positions into accord before frontier collisions should make a peaceable settlement impossible. Thus each will be seen with one hand brandishing violent protests because of insulted national pride, but with the other reaching for some sort of a con- clusive agreement.
