After sinking the "Cumberland," the "Merrimac" again turned on the "Congress" with her entire broadside and, owing to her own impervious character, soon got the Federal ship into such condition, notwithstanding the heroic defence of her men under Lieutenant Smith, who soon was killed, that she had to surrender, and thereafter caught fire from the hot shot of the enemy and was destroyed. The "Merrimac," now under the command of Lieutenant Jones, a rifle ball having struck both Commodore Buchanan and Flag-Lieutenant Minor, not yet satisfied with the destruction which she had wrought, then turned her attention to the remaining Federal ships, the "Minnesota," "St. Lawrence" and "Roanoke," and after having, with the assistance of some accompanying Confederate gunboats, played havoc especially with the "Minnesota," about seven o'clock in the evening, owing to the ebbing tide, turned her head towards Sewell's Point, where she anchored for the night, with the intention of renewing her dread work on the following morning, after one of the most disastrous days in the history of the Federal navy. In selecting the destruction of the "Cumberland" by the "Merrimac" as the subject of this painting, the artist showed his usual good judgment. It was one of the earliest as well as most startling incidents of the entire war, and in its effect in revolutionizing the construction not only of our ships, but those of the world, easily holds first place in all naval history. The picture is wonderfully painted and dramatically handled and is considered by some critics the most interesting of the series. The huge, truncated bulk of the Confederate ram is shown in the act of plunging her prow through the wooden hull of her opponent in the teeth of a broadside of fire and shell. The contrast of colors and values is forcibly expressed; the black soft coal smoke from the single stack of the "Merrimac" drifts forward and envelopes her antagonist as the cuttle-fish darkens the water that it may more easily destroy its victim. An examination of this painting is its best description. It is almost impossible to paint in words the scene which the great artist has here perpetuated with his brush. The water is incomparable and the effect of the shipping as a background, the bright afternoon sun, with the stars and stripes on the "Cumberland," and the stars and bars, the emblem of the Confederacy, on the stern of the death-dealing Southern monster, the crowded deck of the "Cumberland," in contrast with the apparently unmanned craft of the enemy, all add to the thrilling and vivid effect of the extraordinary combat itself.
