The gunboats formed in line of battle, and advanced up the river. The four iron-clads led, steaming abreast. About a mile in the rear, came the three wooden vessels. The fort was soon in range; but both parties seemed anxious for a determined conflict, and no shot was fired on either side as the gunboats came sullenly on. How different must have been the feelings of the two combatants! Tilghman, with his handful of men, hardly able to work eight of the eleven guns mounted in his fort, and knowing that his defeat was a mere question of time; Foote, with his iron-clads and supporting gunboats, his seventy-two guns, and his knowledge that six thousand men were marching upon the rear of the Confederate works. On the one side, all was absolute certainty of defeat; on the other, calm confidence of victory. When the flotilla was within a third of a mile of the fort, the fire began. The gunners on the ships could see the muzzles of the Confederate guns, the piles of shells and cannon-balls, and the men at their work. The firing on both sides was deliberate and deadly. The Confederates were new to the work, but they proved themselves good marksmen. The first shot was fired from the shore, and, missing the "Essex" by but a few feet, plumped into the water, so near the next ship in line as to throw water over her decks. Within five minutes, the "Essex" and the "Cincinnati" were both hit. The armor of the gunboats proved no match for the shots of the Confederates, and in many cases it was penetrated. In some instances, shells, entering through the portholes, did deadly damage.
