The emigration of those Indians who had come in to Fort Brooke, and registered themselves as ready for emigration, was delayed in consequence of the difficulty of collecting those who were expected; and General Jessup began to see the effects which his violation of the articles of capitulation had wrought on the minds of both Indians and negroes. Indeed, he had in plain and distinct language repeatedly affirmed that the negroes _controlled the Indians_; that any interference with the negroes would cause a resort to arms; yet he himself subsequently ordered negroes to be sought out, separated from their friends, and delivered over to slavery. The ships were yet lying in the harbor. About seven hundred Indians were encamped ready for emigration, and had been waiting for others to join them. Impatient at delay and disappointment, on the twenty fifth of May, he wrote Colonel Harney, as follows: "If you see Powell (Osceola) again, I wish you to tell him that I intend to send exploring and surveying parties into every part of the country during the summer, and that I shall send out and _take all the negroes who belong to the white people_, and he must not allow the Indians or Indian negroes to mix with them. Tell him I am sending to Cuba for bloodhounds to trail them, and _I intend to hang every one of them who does not come in_." This intention to reënslave the Exiles who had recently taken up their residence with the Seminoles became known, and created general alarm. Many of the blacks, who had come in for the purpose of emigrating, became alarmed and fled; and General Jessup, doubtful whether more could be obtained by peaceful means, seized about ninety Exiles who were confined within the pickets at Tampa Bay, on the second of June, and at once ordered them to New Orleans, under the charge of Lieutenant G. H. Trevitt, of the United States Marines. This struck the Indians and Exiles with astonishment. The chiefs, warriors and families, numbering some seven hundred, who had collected at Tampa Bay for the purpose of emigrating to the western country, thinking themselves betrayed, now fled to their former fastnesses, far in the interior, and once more determined to defend their liberties or die in the attempt. A few, however, were secured at other posts, and sent to New Orleans, where they were delivered over to Quarter-Master Clark, and confined at "Fort Pike." On the fourteenth of June, General Jessup, writing General Gadsden of South Carolina, says: "_All is lost_, and principally, I fear, _by the influence of the negroes_--the people who were the subject of our correspondence. * * * I _seized_, and sent off to New Orleans, about ninety Indian negroes, and I have about seventeen here. I have captured ninety, the property of citizens; all of whom have been sent to St. Marks and St. Augustine, except four at this place, twelve at Fort Mellon, and six who died."
