the fort, to destroy the railroad bridge over the river connecting Bowling Green with Columbus. The flag-officer deplored that scarcity of men prevented his coming with four other boats, but to man those he brought it had been necessary to strip Cairo of all men except a crew for one gunboat. Only 50 men of the 1,100 promised on December 23d had been received from the army.

Fort Henry was an earthwork with five bastions, situated on the east bank of the Tennessee River, on low ground, but in a position where a slight bend in the stream gave it command of the stretch below for two or three miles. It mounted twenty guns, but of these only twelve bore upon the ascending fleet. These twelve were: one X-inch columbiad, one 60-pounder rifle, two 42- and eight 32-pounders. The plan of attack was simple. The armored gunboats advanced in the first order of steaming, in line abreast, fighting their bow guns, of which eleven were brought into action by the four. The flag-officer purposed by continually advancing, or, if necessary, falling back, to constantly alter the range, thus causing error in the elevation of the enemy's guns, presenting, at the same time, the least vulnerable part, the bow, to his fire. The vessels kept their line by the flag-ship Cincinnati. The other orders were matters of detail, the most important being to fire accurately rather than with undue rapidity. The wooden gunboats formed a second line astern, and to the right of the main division.

Two days previous to the action there were heavy rains which impeded the movements of the troops, caused the rivers to rise, and brought down a quantity of drift-wood and trees. The same flood swept from their moorings a number of torpedoes, planted by the Confederates, which were grappled with and towed ashore by the wooden gunboats.

Half an hour after noon on the 6th, the fleet, having waited in vain for the army, which was detained by the condition of the roads, advanced to the attack. The armored vessels opened fire, the flag-ship beginning, at seventeen hundred yards distance, and continued steaming steadily ahead to within six hundred yards of the fort. As the distance decreased, the fire on both sides increased in rapidity and accuracy. An hour after the action began the 60-pound rifle in the fort burst, and soon after the priming wire of the 10-inch columbiad jammed and broke in the vent, thus spiking the gun, which could not be relieved. The balance of force was, however, at once more than restored, for a shot from the fort pierced the casemate of the Essex over the port bow gun, ranged aft, and killing a master's mate in its flight, passed through the middle boiler. The rush of high-pressure steam scalded almost all in the forward part of the casemate, including her commander and her two pilots in the pilot-house. Many of the victims threw themselves into the water, and the vessel, disabled, drifted down with the current out of action. The contest was vigorously continued by the three remaining boats, and at 1.45 P.M. the Confederate flag was lowered. The commanding officer, General Tilghman, came on board and surrendered the fort and garrison to the fleet; but the greater part of the Confederate forces had been previously withdrawn to Fort Donelson, twelve miles distant, on the Cumberland. Upon the arrival of the army the fort and material captured were turned over to the general commanding.

In this sharp and decisive action the gunboats showed themselves well fitted to contend with most of the guns at that time to be found upon the rivers, provided they could fight bows on. Though repeatedly struck, the flag-ship as often as thirty-one times, the armor proved sufficient to deflect or resist the impact of the projectiles. The disaster, however, that befell the Essex made fearfully apparent a class of accidents to which they were exposed, and from which more than one boat, on either side, on the Western waters subsequently suffered. The fleet lost two killed and nine wounded, besides twenty-eight scalded, many of whom died. The Essex had also nineteen soldiers on board; nine of whom were scalded, four fatally.

The surrender of the fort was determined by the destruction of its armament. Of the twelve guns, seven, by the commander's report, were disabled when the flag was hauled down. One had burst in discharging, the rest were put out of action by the fire of the fleet. The casualties were few, not exceeding twenty killed and wounded.

Flag-Officer Foote, having turned over his capture to the army, returned the same evening to Cairo with three armored vessels, leaving the Carondelet. At the same time the three wooden gunboats, in obedience to orders issued before the battle, started up river under the command of Lieutenant Phelps, reaching the railroad bridge, twenty-five miles up, after dark. Here the machinery for turning the draw was found to be disabled, while on the other side were to be seen some transport steamers escaping up stream. An hour was required to open the draw, when two of the boats proceeded in chase of the transports, the Tyler, as the slowest, being left to destroy the track as far as possible. Three of the Confederate steamers, loaded with military stores, two of them with explosives, were run ashore and fired. The Union gunboats stopped half a mile below the scene, but even at that distance the force of the explosion shattered glasses, forced open doors, and raised the light upper decks.

The Lexington, having destroyed the trestle-work at the end of the bridge, rejoined the following morning; and the three boats, continuing their raid, arrived the next night at Cerro Gordo, near the Mississippi line. Here was seized a large steamer called the Eastport, which the Confederates were altering into a gunboat. There being at this point large quantities of lumber, the Tyler was left to ship it and guard the prize.

The following day, the 8th, the two boats continued up river, passing through the northern part of the States of Mississippi and Alabama, to Florence, where the Muscle Shoals prevented their farther progress. On the way two more steamers were seized, and three were set on fire by the enemy as they approached Florence. Returning the same night, upon information received that a Confederate camp was established at Savannah, Tennessee, on the bank of the river, a party was landed, which found the enemy gone, but seized or destroyed the camp equipage and stores left behind. The expedition reached Cairo again on the 11th, bringing with it the Eastport and one other of the captured steamers. The Eastport had been intended by the Confederates for a gunboat, and was in process of conversion when captured. Lieutenant Phelps reported her machinery in first-rate order and the boilers dropped into the hold. Her hull had been sheathed with oak planking and the bulkheads, forward, aft, and thwartships, were of oak and of the best workmanship. Her beautiful model, speed, and manageable qualities made her specially desirable for the Union fleet, and she was taken into the service. Two years later she was sunk by torpedoes in the Red River, and, though partially raised, it was found impossible to bring her over the shoals that lay below her. She was there blown up, her former captor and then commander, Lieutenant Phelps, applying the match.

Lieutenant Phelps and his daring companions returned to Cairo just in time to join Foote on his way to Fort Donelson. The attack upon this position, which was much stronger than Fort Henry, was made against the judgment of the flag-officer, who did not consider the fleet as yet properly prepared. At the urgent request of Generals Halleck and Grant, however, he steamed up the Cumberland River with three ironclads and the wooden gunboats, the Carondelet having
