The Monitor arrived during the evening and anchored under the stern of the Minnesota, her lighter draught enabling her to do so without danger. To us the ensuing engagement was in the nature of a surprise. If we had known we were to meet her we would at least have been supplied with a solid shot for our rifled guns. We might even have thought best to wait until our iron beak, lost in the side of the Cumberland, could be replaced. Buchanan was incapacitated by his wound and the command devolved upon Lieutenant Jones.

We left our anchorage shortly before eight o'clock next morning and steamed across and up stream toward the Minnesota, thinking to make short work of her and soon to return with her colors trailing under ours. We approached her slowly, feeling our way cautiously along the edge of the channel, when suddenly, to our astonishment, a black object that looked like the historic description, "a barrel-head afloat with a cheese-box on top of it," moved slowly out from under the Minnesota and boldly confronted us. It must be confessed that both ships were queer-looking craft, as grotesque to the eyes of the men of '62 as they would appear to those of the present generation.

And now the great fight was on, a fight the like of which the world had never seen. With the battle of yesterday old methods had passed away, and with them the experience of a thousand years "of battle and of breeze" was brought to naught. The books of all navies were burned with the Congress, by a conflagration as ruthless as the torch of Omar. A new leaf had been turned, a virgin page on which to transcribe and record the art of naval warfare.

We hovered about each other in spirals, gradually contracting the circuits, until we were within point-blank range, but our shell glanced from the Monitor's turret just as hers did from our sloping sides. For two hours the cannonade continued without perceptible damage to either of the combatants.

On our gun-deck all was bustle, smoke, grimy figures, and stern commands, while down in the engine and boiler rooms the sixteen furnaces were belching out fire and smoke, and the firemen standing in front of them, like so many gladiators, tugged away with devil's-claw and slice-bar. inducing by their exertions more and more intense heat and combustion. The noise of the crackling, roaring fires, escaping steam, and the loud and labored pulsations of the engines, together with the roar of battle above and the thud and vibration of the huge masses of iron being hurled against us, altogether produced a scene and sound to be compared only with the poet's picture of the lower regions.

And then an accident occurred thar threatened our utter destruction. We stuck fast aground on a sandbar.

Our situation was critical. The Monitor could, at her leisure, come close up to us and yet be out of our reach, owing to an inability to deflect our guns. In she came and began to sound every chink in our armor--every one but that which was actually vulnerable, had she known it.

The coal consumption of the two days' fight had lightened our prow until our unprotected submerged deck was almost awash. The armor on our sides below the water-line had not been extended but about three feet owing to our hasty departure before the work was finished. Lightened as we were, these exposed portions rendered us no longer an ironclad, and the Monitor might have pierced us between wind and water had she depressed her guns.

Fearing that she might discover our vulnerable "heel of Achilles," while she had us "in chancery," we had to take all chances. We lashed down the safety valves, heaped quick-burning combustibles into the already raging fires, and brought the boilers to a pressure that would have been unsafe under ordinary circumstances. The propeller churned the mud and water furiously, but the ship did not stir. We piled on oiled cotton waste, splints of wood, anything that would burn faster than coal. It seemed impossible the boilers could long stand the pressure we were crowding upon them. Just as we were beginning to despair there was a perceptible movement, and the Merrimac slowly dragged herself off the shoal by main strength. We were saved.

Before our adversary observed we were again afloat we made a dash for her, catching her quite unprepared, and tried to ram her, but our commander was dubious about the result of a collision without our iron-shod beak and gave the signal to reverse the engines long before we reached the Monitor. As a result I did not feel the slightest shock down in the engine-room, though we struck her fairly enough.

The carpenter reported that the effect was to spring a leak forward. Lieutenant Jones sent for me and asked me about it.

"It is impossible we can be making much water," I replied," for the skin of the vessel is plainly visible in the crank-pits."

A second time he sent for me and asked if we were making any water in the engine room.

"With the two large Worthington pumps, beside the bilge injections, we could keep her afloat for hours, even with a ten-inch shell in her hull." I assured him, repeating that there was no water in the engine and boiler rooms.

We glided past, leaving the Monitor unscathed, but got between her and the Minnesota and opened fire on the latter. The Monitor gallantly rushed to her rescue, passing so close under our submerged stern that she almost snapped off our propeller. As she was passing, so near that we could have leaped aboard her, Lieutenant Wood trained the stern-gun on her when she was only twenty yards from its muzzle and delivered a rifle-pointed shell which dislodged the iron logs sheltering the Monitor's conning tower, carrying away the steering-gear and signal apparatus, and blinding Captain Worden. It was a mistake to place the conning tower so far from the turret and the vitals of the ship. Since that time it has been located over the turret. The Monitor's turret was a death-trap. It was only twenty feet in diameter, and every shot knocked off bolt-heads and sent them flying against the gunners. If one of them barely touched the side of the turret, he would be stunned and momentarily paralyzed. Lieutenant Greene had been taken below in a dazed condition and never fully recovered from the effects. One of the port shutters had been jammed, putting a gun out of commission, and there was nothing for the Monitor to do but to retreat and to leave the Minnesota to her fate.

Captain Van Brunt, of the latter vessel, thought he was now doomed and was preparing to fire his ship when he saw the Merrimac also withdrawing forward Norfolk.

It was at this juncture that Lieutenant Jones had sent for me and said: "The pilots will not place us nearer to the Minnesota and we cannot afford to run the risk of getting aground again. I am going to haul off under the guns of Sewall's Point and renew the attack on the rise of the tide. Bank your fires and make any necessary adjustments to the machinery, but be prepared to start up again later in the afternoon."

I went below to comply with his instructions, and later was astonished to hear cheering. Rushing on deck I found we were passing Craney Island on our way to Norfolk, and were being cheered by the soldiers of the battery.
