General Eustis, commanding the left wing, arrived at St. Augustine on February 15th, and at once established a chain of posts at intervals of from ten to twenty miles, extending along the Atlantic coast as far south as the Mosquito Inlet, in order to drive off the bands of depredators and to give protection to the plantations. Colonel Goodwyn's mounted South Carolina volunteers having arrived on March 9th, the several detachments of the left wing, with the exception of Colonel Pierce M. Butler's battalion and two companies of artillery under Major Reynold M. Kirby, were put in motion for Volusia, where they arrived on March 21st after encountering great difficulties, being compelled to cut the road nearly the whole distance. On the 22d they began crossing the St. John's River. When the vanguard, consisting of two companies under Captains Adams and T.S. Tripp, had reached the opposite shore they were attacked by about fifty Indians who were concealed in a hammock. Being re-enforced by George Henry and Hibler's companies, they charged the enemy and drove him. Two companies of mounted men were crossed above with a view of cutting off the retreat of the Indians, but they were too late. The loss in this battle was three killed and nine wounded. On the 24th, Lieutenant Ripley A. Arnold, with twenty-seven mounted men, was sent in quest of Colonel Butler and his command, who had not joined the main command, he having marched in the direction of New Smyrna. This detachment fell in with a party of twelve or fifteen Indians who gave battle. Two of the Indians were killed, and Lieutenant Arnold, having his horse shot, ordered a retreat, for which he was severely censured. The whole force of General Eustis's command being now concentrated on the west side of the St. John's River, opposite to Volusia, orders were issued to distribute thirteen days' rations, and the line of march to be taken up for Pilaklakaha, leaving the sick and wounded with two companies of Colonel Brisbane's regiment at Volusia, under command of Major William Gates, United States army. The roads being bad, they were unable to march more than seven miles in two days. On the 29th they reached the Ocklawaha, and, constructing a bridge, crossed over after sundown and discovered fires on the margin of Lake Eustis, which they supposed to be signals of the Indians. Colonel Butler, with a small command, accompanied by General Joseph Shelton, who was serving as a private soldier, moved in the direction of the fires and discovered four Indians, who at once retreated. One of these Indians, Chief Yaha Hayo, was killed, while the others made their escape. On the 30th Colonel Goodwyn was sent forward to reconnoiter, and when near Pilaklakaha was attacked by Indians, having three men and several horses wounded. Colonel Robert H. Goodwyn was soon re-enforced by General Eustis, and a battle ensued lasting nearly an hour. The Indians were driven into the swamp.
