pass to the attack. It ascended to such a degree that our batteries could not well fire from the rear without the risk of hitting our own troops. Further, the location of the rebel batteries was so high, and they were so well protected by earthworks, that an effective fire could not easily be brought to bear upon them. Moreover, the field afforded hardly any other than greatly exposed positions for our batteries. The outcome of several attempts made before Hooker's to employ them showed this. Dickinson's mounted battery of four 10-pounders was called forward after French's and Hancock's repulse, and opened fire from the outskirts on the left; but its commander and one-fourth of the gunners and horses were killed and disabled in a short time, compelling it to retire. Arnold's battery of six rifled guns was put to use near the same point, but their fire was impeded by our columns coming within range. Two New York batteries also supported our advances as well as possible. This and the prelude to Butterfield's attack constituted the artillery's part in the day's work on our right.
It was Captain Hazard's regular-army battery of six 12-pounders and four pieces of Captain Frank's battery, of the same calibre, to which the perilous duty of leading off in the last effort to storm the enemy's position was assigned. They had already started for the front when I met Hooker and Butterfield. They reached a favorable point for their work within two hundred yards of the death-dealing stone wall. In a few minutes after they had opened a most vigorous fire, the horses of all the officers were shot under them, and such further havoc caused among the gunners and animals that Captain Hazard impressed some of the infantry near him to serve his pieces. The batteries held their ground until they were ordered to withdraw.
The execution of the dread task of the Fifth Corps devolved upon Humphreys's division of two brigades. Allabach's second brigade took the lead, and was formed for
