McClernand continued pressing all day to his right, following the course of the ridge along which the Wynn's Ferry road passes. By night his right nearly or quite reached the point where the Wynn's Ferry road issued from the intrenchments. His artillery was very active; the companies acting at times separately, at times uniting and concentrating their fire on some well-served battery, they silenced temporarily several batteries, and in the afternoon shelled some camps. A determined assault was made on the position held by Maney's battery, supported by Colonel Heiman with the Tenth, Forty-eighth, and Fifty-third Tennessee, and the Twenty-seventh Alabama. This position was, at the same time, the most salient and the most elevated in the entire line of intrenchment. It was so traced that both faces were swept by artillery and infantry fire from portions of the works to the right and the left. Colonel Morrison was directed with his brigade, the Seventeenth and Forty-ninth Illinois, to assault this position. Colonel Haynie, of the Forty-eighth Illinois, senior to Morrison, was ordered to join him and take the command. Morrison, on the right, assaulted the left face of the work; the Seventeenth and Twenty-fifth assaulted the right. Crossing the valley, they began the ascent, encountered the tangled abattis, and while striving to tear their way through it, under a plunging fire from the battery and the infantry above them, they were assailed by artillery and infantry from a long extent of line beyond. They recoiled from this toil and this double fire. The Forty-fifth Illinois was sent to reinforce Morrison. The four regiments started again, forced their way still farther up the abattis, and were again repelled. Undaunted, they rushed up the hill-side the third time. Part of the command pierced through the abattis and reached the rifle-pits. The summit of the rifle-pits was a blaze of musketry. Maney's guns hurled shrapnel into their faces. To Morrison's right and to Haynie's left, the long line of rifle-pits was a line of musketry, and from projecting points the batteries sent their fire. Morrison was wounded. His men could not climb over the intrenchment. The regiments recalled, fell back in order out of fire. The dead leaves on the hill-side were inflamed in some way, in this close contest, and when artillery and musketry had ceased, helpless wounded lying on the hill-side were burned to death. Colonel Heiman's men, leaping over their works, were able to save some. General Buckner reported his loss in the assault on Hanson's position as thirty-nine killed and wounded. Ten killed and thirty wounded were reported as Heiman's loss, most of them in Maney's battery. Nearly every regiment in the entire line of the intrenchments suffered some casualties from the National artillery. The national loss was more severe. The pertinacity of the attack through the day prevented the besieged from suspecting the inferiority in numbers of the attacking force.
