About daylight Breckinridge moved to the attack in a summer fog so dense that those engaged could at first distinguish neither friend nor enemy. The blow fell first, and heavily, upon the centre and right, held by the 14th Maine, 21st Indiana, and 6th Michigan. As our troops were pressed back by the vigor of the first onset, the exposed camps of the 14th Maine, 7th Vermont, and 21st Indiana fell into the hands of the Confederates. The 9th Connecticut, with Manning's battery, moved to the support of the 14th Maine and 21st Indiana, on the right of the former, and the 4th Wisconsin formed on the left of the 14th. Further to the right, the 30th Massachusetts advanced to the support of the 21st Indiana and 6th Michigan, covering the interval between the two battalions to replace the 7th Vermont. In the first fighting in the darkness and the fog this regiment had been roughly handled; its colonel fell, a momentary confusion followed, and the regiment drifted back into a convenient position, where it was soon reformed, under Captain Porter. Nims brought his guns into battery on the right of the 6th Michigan. The battle was short, but the fighting was severe; both sides suffered heavily, and each fell into some disorder. At different moments both wings of the Confederate force were broken, and fell back in something not very unlike panic. The colors of the 4th Louisiana were captured by the 6th Michigan. As the fog lifted, under the influence of the increasing heat, it became clear to both sides that the attack had failed. The force of the fierce Confederate outset was quite spent. The Union lines, however thinned and shattered, remained in possession of the prize. "It was now ten o'clock," says Breckinridge. "We had listened in vain for the guns of the _Arkansas_: I saw around me not more than 1,000 exhausted men." The battle was over. Indeed it had been over for some hours; these words probably indicate the period when the Confederate commander gave up his last hope. The _Arkansas_, disabled within sight of the goal by an accident to her machinery, was run ashore and destroyed by her commander to save her from capture. The Confederate losses were about 84 killed, 313 wounded, and 56 missing; total, 453. Clark was severely wounded and made prisoner. Allen was killed, and two other brigade commanders wounded. Helm, Hunt, and Thompson had been previously disabled by an accident during the night panic. The Union losses were 84 killed, 266 wounded, and 33 missing; total, 383. The heaviest loss fell upon the 21st Indiana, which suffered 126 casualties, and upon the 14th Maine, which reported 118. Of the killed, 36, or nearly one half, belonged to the 14th Maine, while more than two thirds of the killed and nearly two thirds of the total belonged to that regiment and the 21st Indiana. The 4th Wisconsin, being posted quite to the left of the point of attack, was not engaged.
