of the Third Brigade of this division in three lines. Brevet Brigadier-General Gregory, commanding Second Brigade of this division, reported to me with his brigade, by order of General Griffin, and was placed upon the right flank of our lines, one regiment being deployed as skirmishers in our front, one on the flank faced outward, and one held in reserve. Mackenzie's cavalry was on or right. In this formation we advanced in the order designated. Our instructions were to keep closed to the left on the Third Brigade, and also to wheel to the left in moving, the design being to strike the enemy in flank. We advanced thrugh an open wood with nothing but light skirmishers in our front for some time. The constant change of direction to the left made the march on the right flank exceedingly rapid. On coming out at a large opening it was discovered that the Third Division of the corps was no longer on the left of the First Division, as had been the order of movement, and the heavy firing was all concentrated at a int to our left and front, where the Second Division had struck the enemy's works. Seeing the division flag moving in that direction I immediately drew my brigade into the field moving in that direction I immediately drew my brigade into the field by the left flank and formed them facing this fire, and General Griffin ordered me to move against the point. Brevet Major-General Bartlett advanced at the same time with three regiments of the Third Brigade immediately on my right. We moved up rapidly under the crest of a hill and charged the works, striking them obliquely in flank and reverse, the right of my line-the One hundred and eighty-fifth New York (Colonel Snope) and the first battalion of the One hundred and ninety-eighth Pennsylvania (Major Glenn)-passing down to the rear of the works, and the left-second battalion of the One hundred and ninety-eighth (Captain Stanton)-passing in front of them. The regiments of the Third Brigade, striking farther up, met a very heavy flank fire on the right, which broke us up somewhat, the extreme right falling back and the remainder of the line showing strong disposition to swing to the left into the works form which we had driven the enemy, a position which would render them powerless against the flank attack which was then commencing. It required the utmost personal efforts of every general and staff officer present to bring our line to face perpendicularly ot the line of works, and to repulse the attack. General Bartlett informing me of the imminent peril on his right I directed my two right regiments to sweep down the rear of the Twentieth Miane and First michigan and break the attack, General Gregory also pressing forward with his brigade in the same direction. In the attempt to do this the regiments of the several brigades became somewhat mixed, but a new direction was given to our line, and the enemy completely put to rout. In the meantime, with one staff officer and Captain Brinton, of the division staff, I assisted General Bartlett in collecting the stragglers from all commands who were seeking shelter in the edge of the woods; these men, to the number of 150 or 200, were formed and pushed in. While engaged in this I saw in the open field in our rear the flag of General Gwyn, of the Second Division, and dispatched Lieutenant Fisher, of my staff, to request him to throw his brigade in as rapidly as possible in the same direction as had been given to the troops already in. This assistance was not cheerfully and promptly rendered, and contributed in a good degree to our success. The confusion of the battle at this moment was great; different commands were completely mingled, but our line was still good. The men of my own brigade were, for the most part, nearest to the line of works, thorough many of them were mixed with those of the Twentieth Maine
