At twelve o’clock, the magazines blew up with a terrific noise. This event had been anticipated by the garrison, and the shores and adjacent camps were crowded with awe-struck gazers. The whole upper works of the frigate had, hours before, been reduced to ashes by the devouring flames; the masts and spars, blackened and charred, had fallen into and across the burning hull; these were sent high into the air with other debris, and as blast succeeded blast, were suddenly arrested in their descent and again sent heavenward. The spectacle thus presented was awfully grand; a column of fire and sulphurous smoke, fifty feet in diameter at its base and not less than two hundred feet high, dividing in its centre into thousands of smaller jets, and falling in myriads of bunches and grains of fire, like the sprays of a gigantic fountain, lighted up the camp and bay for miles.

The yards and rigging of the “Minnesota” and “St. Lawrence” were filled with men armed with fire-buckets, lest the falling sparks should ignite the tarred ropes of these vessels, and unite them in one general conflagration. The sides of the hapless “Congress” were thrown open by the last explosion, and the next morning, all that could be seen of the once proud ship were a few blackened ribs, a short distance above the surface of the water.

When the soldiers of Camp Butler turned away from that scene to retire to their quarters, it was with heavy hearts. The recollection of the harrowing events of the afternoon was still fresh in their minds; they had now witnessed the total destruction of another vessel of our navy, the loss of which gave joy to the South, a new lease of life to the Rebellion, and operated to postpone the day when they would be permitted to doff the blue and return to their homes.

Sunday the 9th of March dawned, finding the frigate “Minnesota” still aground, her consort, the “St. Lawrence,” having more fortunately drifted into deep water. The day broke fair, and so calm was everything upon both water and land, that it seemed very like a preparation for the funeral of the two hundred brave men who had tasted death on the preceding day. The Confederate fleet could be distinctly seen lying at anchor under their batteries at Sewall’s Point. A column of white steam was issuing from the pipes of the “Merrimack”; it was evident that she was preparing to set out on her second day’s exploits, and attempt to deal the final blow to our navy in Hampton Roads. At about seven o’clock, the “Merrimack” was discovered to be moving, and following her were the other vessels of the Confederate fleet. Upon rounding the Point, the iron-clad shaped her course directly towards Fortress Monroe, but she had not proceeded far before she suddenly turned and steered toward the mouth of the James. The drums of the “Minnesota” were heard beating her anxious crew to quarters. When the “Merrimack” had arrived within fair range, she fired a shot from her bow gun. The shot struck the frigate under her counter, doing her not a little damage. The fire was quickly replied to by the frigate, and now Captain Van Brunt, her commander, signalled the “Monitor,” which up to that moment had lain close alongside of the ship, and which had arrived from New York the night before, to attack the enemy.

This diminutive craft had not until this time been seen by our men on shore, although rumors of its arrival had spread through camp; and as it steamed out upon the bay, wonder as to what it was, and what it would be likely to accomplish, seized fast hold upon all. With apparent confidence in its ability to contend with the monster iron-clad of the enemy, the “Monitor” steamed directly toward it, and when within one hundred yards, opened fire. The report of that gun rang out so loud upon the still air of the morning, as to immediately create a feeling of confidence in the ability of the little boat to contend successfully with the enemy. In less than five minutes from that time, the two vessels were hotly engaged with each other, belching out fire and iron in each others’ faces.

The other vessels of the enemy were by this time fairly engaged with the “St. Lawrence,” “Minnesota,” and the Federal gunboats, and were soon put to flight, keeping well off toward the opposite shore. Shortly after the “Merrimack” had fired her first broadside at the “Monitor,” and had seen her shots glance harmlessly from the revolving turret, she tried the experiment of sinking her, and after backing off slowly, ran at her, head on. The prow of the “Merrimack” struck the “Monitor,” but glanced, and the little vessel swung around, delivering in this position several of her most effective shots in rapid succession. After this the combatants parted, and a brief truce followed, at the close of which the two vessels again neared each other, and a second duel, fiercer and more desperate if possible than the first, ensued.

At one time during the battle, the Confederate steamer “Jamestown” ventured to interfere on the side of the “Merrimack,” but received from the “Monitor” a shot that pierced her sides, and disabled her to such a degree as to cause her to haul off. During much of the time that the two iron-clads were actively engaged, they were scarcely visible from the shore, being enveloped in clouds of smoke; but occasionally the garrison were disagreeably reminded of what was going on by a huge shot from one or the other of the vessels missing its mark and reaching the land. Several of these huge missiles went bounding over the long plain, casting the dust high into the air, and plowing up the earth in deep, irregular furrows.

At about twelve o’clock, while the “Monitor” was apparently resting, being separated by the distance of a mile from her antagonist, the “Merrimack” made a sudden movement towards the “Minnesota.” The tide being at its height, it was doubtless supposed by the enemy that he could reach the frigate, and give her a death-blow with his prow. The “Minnesota” opened upon the enemy with all her broadside guns and ten-inch pivot; “a broadside,” says Captain Van Brunt in his report, “that would have blown out of the water any timber-built ship in the world.” The “Merrimack” replied with her rifled bow gun “with a shell which passed through the chief engineer’s stateroom, through the engineer’s messroom amidships, and burst in the boatswain’s room, tearing four rooms all into one; in its passage, exploding two charges of powder, which set the ship on fire.”[26]... The fire was quickly extinguished; but the alarm of fire having reached the ears of the men, great consternation prevailed for several minutes. A second shot from the ram went through the boiler of the gunboat “Dragon,” which lay near the “Minnesota,” exploding it, and badly scalding and wounding a number of our sailors. The position of the enemy was now such as to enable the “Minnesota” to concentrate upon him a heavy fire from her gun-deck, spar-deck, and forecastle pivot-guns; and it was stated by the marine officer of the frigate, who was stationed on the poop, that at least fifty solid shot struck the slanting side of the “Merrimack” during this fire, but without producing any apparent effect.

By the time the “Merrimack” had fired her third shot at the “Minnesota,” the “Monitor” had reached the scene of action, and immediately ran in between the two vessels, covering by her turret, as far as possible, the already badly-injured frigate. This movement of the “Monitor” caused the “Merrimack” to change her position, in doing which she grounded. Again the frigate, aided by the “Monitor,” poured into the ram every available gun; but the stanch iron-clad withstood the combined fire of both our vessels, and in the course of a few minutes floated, shaping her course down the bay, being closely followed by the “Monitor.” In the course of this pursuit, the “Merrimack” suddenly turned, and with full head of steam, struck the “Monitor” for the second time with her prow; but the blow produced no effect, while the “Monitor” fired a solid shot that plunged into the enemy’s roof. Then followed a cannonade more desperate, if possible, than any which had preceded it. The “Merrimack” brought four of her guns to bear upon the “Monitor’s” turret and pilot-house. In the latter was Lieutenant Worden, watching the progress of the battle. An immense solid shot struck the house with such force as to loosen the cement about the inside of the structure, and set in motion a fragment of it, which struck the gallant lieutenant in one of his eyes. The concussion and the blow completely stunned him, rendered him senseless, and disabled him for further duty during the battle. Soon after this accident, the “Monitor” stood down for Fortress Monroe, when the “Merrimack” and two of her consorts again turned toward the stranded frigate. Captain Van Brunt had nearly expended all his solid shot, his ship was already badly crippled, and his officers and men worn out by their excessive labor. It is no wonder, therefore, that when he saw the near prospect of another terrible struggle with the invulnerable enemy, that the thought of burning his vessel came into his mind, for, to use his language, “I determined never to give up the ship to the rebels.” Fortunately the “Merrimack” was satisfied that her efforts to further cripple our fleet could not succeed, and being herself more or less disabled, headed toward Norfolk, the “Monitor,” to the unspeakable joy of the spectators, starting in pursuit. The chase, which was continued for several miles, and then abandoned, was not attended with any tiring on the part of either vessel. This was the closing scene of this remarkable battle.

The excitement in Camp Butler was not to end just here. The men had hardly swallowed their dinner, before a number of horsemen came riding into camp, their horses flecked with foam and themselves covered with dust. They had come from the outposts to inform General Mansfield that the enemy in large numbers were advancing, and that an attack was imminent. The long roll was again beaten, and the excited men mustered with no less alacrity than on the previous day. The Twenty-ninth Regiment formed in line of battle just inside the breastworks, and as it stood there anxiously gazing in the direction of the forest, Lieutenant-Colonel Barnes, then in command, rode to the front, and uttered these words: “Men, we may be called upon to meet the enemy in battle this afternoon, the most of you for the first time. Remember that you are the only Massachusetts troops in this camp!” The emotion of pride and sense of responsibility which these simple words awoke in the breasts of the men was manifested by a hearty cheer all along the line. Things looked very much like a fight at that moment; the entire garrison was under arms, and General Mansfield, mounted, was moving briskly about the camp, speaking cheering words to the troops. This was his speech to the Twenty-ninth: “My men, Magruder is up the river with ten thousand troops. I have in camp six thousand men with muskets and a million rounds of cartridges; and so long as there is left me a man, a musket, or a cartridge, I’ll keep that flag flying!” pointing to the post flag flying near his quarters.
