Three or four days were passed in this way, while the gun-boats were slowly making their way up the river. It was Colonel Clinch's purpose to have the gun-boats shell the fort, while he should storm it on the land side. The work promised to be bloody, and it was necessary to bring all the available force to bear at once. There were no siege-guns at hand, or anywhere within reach, and the only way to reduce the fort was for the small force of soldiers--numbering only one hundred and sixteen men--to rush upon it, receiving the fire of its heavy artillery, and climb over its parapets in the face of a murderous fire of small-arms. Garcon had with him three hundred and thirty-four men, so that, besides having strong defensive works and an abundant supply of large cannon, his force outnumbered Colonel Clinch's nearly three to one. It is true that the American officer had the band of Seminoles with him, but they were entirely worthless for determined work of the kind that the white men had to do. Even while lying in the woods at a distance, waiting for the gun-boats to come up, the Indians became utterly demoralized under the fire of Garcon's 32-pounder. There was nothing to be done, however, by way of improving the prospect, which was certainly hopeless enough. One hundred and sixteen white men had the Negro Fort to storm, notwithstanding its strength and the overwhelming force that defended it. But those one hundred and sixteen men were American soldiers, under command of a brave and resolute officer, who had made up his mind that the fort could be taken, and they were prepared to follow their leader up to the muzzle of the guns and over the ramparts, there to fight the question out in a hand-to-hand struggle with the desperadoes inside. Finally the gun-boats arrived, and preparations were made for the attack. Sailing-master Jairus Loomis, the commandant of the little fleet, cast his anchors under the guns of the Negro Fort at five o'clock in the morning on the 27th of July, 1816. The fort at once opened fire, and it seemed impossible for the little vessels to endure the storm of shot and shell that rained upon them from the ramparts above. They replied vigorously, however, but with no effect. Their guns were too small to make any impression upon the heavy earthen walls of the fortress.
