The Confederate force in the State of Florida at that time was much larger in proportion to the population, than in other Southern States, as in addition to eight or ten thousand regular troops, the Governor had enrolled most of the arms-bearing population in a home organization for self-defence, and thus evaded the sweeping conscription of the Davis administration which had been so unsparing in other quarters. On the eighth of February, Brigadier-General Truman Seymour, under instructions of General Gilmore, landed at Jacksonville, and occupied the town. His force consisted of seven thousand men, and was conveyed from the Department headquarters in twenty steamers and eight schooners. On the afternoon of the eighth he commenced his march for the interior of the State, his army moving in three columns, which were commanded by Colonels Barton, Hawley, and Henry. Colonel Barton moved on the main road, while the commands of Colonels Hawley and Henry marched on parallel roads to the right of Colonel Barton, which united, at a distance of only three miles, where the infantry camps were spread for the night; while a battalion of cavalry, Elder’s horse Battery B, First artillery, and the Fourth Massachusetts infantry, under Colonel Guy V. Henry, pushed forward on a reconnoissance toward Lake City, through a dense pine forest, and over a low, marshy soil. After riding a distance of eight miles, they surprised and captured an artillery camp of the rebels, containing four guns, with the camp equipage and officers’ baggage. Only three prisoners were taken, the rest of the force effecting their escape. The advance of the army reached Baldwin the next morning, capturing some army stores, and Generals Gilmore and Seymour arrived at that place in the evening.
