The destruction of the Cumberland and Congress on the first day of the engagement, and the triumphant condition in which the Merrimac had retired from the heavy broadsides of the Federal frigates, which would almost have destroyed an ordinary vessel, created intense excitement in all the seaport cities of the North. The loud boasts of the rebels over the strength, sailing qualities, and impregnable character of their vessel, apparently justified by the events of March 8th, led to an apprehension that she might be successful in running out to sea, and visiting Philadelphia, New York, Boston, and other cities, which were entirely unprepared for a sudden attack.

The appearance of the Monitor alongside of the Minnesota, on the morning of the 9th, was altogether unexpected, and the rebel commander evidently knew that he had no common foe with which to deal.

CAPTURE OF JACKSONVILLE, FLA.

March 12, 1862.

Jacksonville, the principal town in East Florida, is situated on the St. John’s river, twenty miles from the sea. Vessels drawing twelve feet of water can cross the bar. An important commercial city of Florida, it was desirable to restore it to the protection of the government, and after the capture of Fernandina, the commanders of the expedition turned their attention to the accomplishment of this object. The United States gunboat Ottawa, in company with the Pembina and Seneca, succeeded in crossing the bar off Jacksonville, on the 11th of March. Commodore Rogers found to his great satisfaction, as already at Fernandina and St. Mary’s, no attempt to dispute his progress or resist the restoration of the city to its allegiance to the government.

Contrary to expectation on both sides, the approaches to this place by the river were not defended, and no resistance was offered to the Union forces by land or water. As at Fernandina, the batteries were evacuated, and the guns for the most part left behind. This was by order of General Trapier, who is said to have acted upon orders from General Lee, commanding the Confederate troops on the South Carolina, Georgia and Florida coast. There were some five thousand rebel troops in this part of Florida—at Fernandina, and on the line of the railroads to Tallahassee and Cedar Keys.

When it was ascertained by the Mayor of the city that the troops were to be withdrawn, he held a consultation with General Pyles, in company with a portion of the city council, in which the question of resistance was freely discussed. The retirement of the troops, and the entirely defenceless condition in which the people had been left, allowed them no choice had they been ever so much determined to dispute the entry of the Federal forces. The Mayor, H. H. Hoeg, issued a proclamation, informing the citizens that no opposition would be made, and calling upon all the inhabitants to treat their expected visitors with proper decorum, and to do nothing that would provoke any ill-feeling between citizens and soldiers.

On the arrival of the vessels Lieutenant Stevens was politely received by the authorities, who came on board his vessel, the Ottawa, and through S. L. Burritt, Esq., gave up the town. Many of the inhabitants had abandoned their homes, fearing to trust the Federal troops. Others, however, remained, and testified their gratification at the arrival of the fleet.

Unfortunately, however, they did not reach Jacksonville in time to save that beautiful town from the flames, as a part of it was laid in ruins. On the afternoon of the 11th, some five or six hundred armed men, claiming to be a part of the force which had been stationed at Fernandina, arrived by railroad, and announced that they had come, by order of General Trapier, to burn the steam saw-mills, lumber, etc., which might be of value to the Federal authorities. No time was given to save property of any description. At dusk the torch was applied, and in a brief space eight of these immense establishments, forming nearly a circle on both sides of the river, were in a blaze. Immediately afterwards, the spacious and elegant hotel, well known to Northern invalids as the Judson House, was fired by unknown persons, together with warehouses, the railroad freight depot, etc., etc. All this property was a total loss to the owners, as no attempt was made to save or rescue any portion of it. The loss was estimated at half a million of dollars.

The population of Jacksonville, before the war broke out, was about four thousand. It had a large trade, as the St. John’s river is settled with plantations, and is navigable for two hundred miles above the town for large vessels, and there were a dozen steamers running on it. The lumber trade was very extensive and prosperous. About fifty million feet of Florida pitch pine were sawed there annually. This business was ruined by the incendiaries. The exports of rosin, turpentine, etc., amounted to $100,000 annually; cotton, $250,000; cedar, $100,000, etc. The arrivals of vessels were about 400 yearly. The town was built mainly of brick, lighted with gas, and was a great resort for invalids, for its mild and balmy climate. The Florida, Atlantic and Gulf rail road, starting here, intersects with the road from Fernandina to Cedar Keys, twelve miles from Jacksonville, and then goes on to Tallahassee, the capital, one hundred and sixty miles, and thence eighteen miles to St. Mark’s, on the Gulf.
