A court of inquiry was duly convened for the purpose of ascertaining the cause of delay under General Scott.[88] Several months now passed without any important incident to mark the progress of hostilities. As the summer approached and the sickly season commenced, General Scott left Florida, and the command of the army, for the time, devolved on General C. K. Call. The allied forces seemed to have retired to the interior, and were supposed to be engaged in raising corn and other provisions, for their support during the coming winter, and all appeared quiet. Osceola, after the death of Thompson at Fort King, had become a master-spirit among the Seminoles. He had conducted bravely during the battle with General Clinch, and equally so in the several conflicts with General Gaines, and had been raised to the dignity of a chief. He now conceived, and executed, one of the boldest movements ever made by savages against a fortified post manned by regular troops. On the ninth of June, with three hundred warriors, some sixty of whom were negroes, he attacked the stockade at Micanopy, garrisoned by an equal force of disciplined troops, under the command of Major Heilman. The assault was maintained with determined obstinacy for an hour and a half, the assailants boldly facing the artillery, which was brought to bear upon them; and when they left the scene of action, they carried away their dead and wounded. Although this attack proved unsuccessful, it gave the country to understand, in some degree, the character of the enemy with whom our Government was contending. Major Heilman, in his report, regrets the severe wound of Capt. Lee; but says nothing of his other loss, or that of the allies, either in killed or wounded. He himself died soon after, from excessive fatigue during the action. Soon after this attack the allies became again active, making their appearance at various points on the frontier, again spreading devastation wherever they went. Major General Jessup continued in Georgia, engaged in constraining the Creeks to emigrate. In this he was very successful, and for that reason was ordered to take command of the army in Florida. With this view he repaired to Tallahasse, where he met General Call, who laid before him a plan, which he had conceived, for an expedition to Withlacoochee. General Jessup, not having received his instructions for prosecuting the campaign, refused to assume the command at that time, leaving General Call to carry out his contemplated movement. General Clinch owned a plantation some twenty miles northwesterly of Fort King. During the early part of the season he had encamped there with his troops, and planted sugar-cane, and other crops; and, being occupied as a military post, he gave it the name of "Fort Drane."
