While the conflict to the right was hotly raging, General French was pushing the rebels severely on the left. This division crossed Antietam creek, in three columns, and marched a mile, to the ford. Then, facing to the left, it moved direct upon the enemy. The division was assailed by a brisk artillery fire, but it steadily advanced, driving back the rebel skirmishers, to a group of houses on a piece of land called Roulette’s farm, where the Federals encountered the rebel infantry in large force, but soon drove them from their position. The brigade of General Kimball was next pushed forward, by General French, in obedience to orders received from his corps commander. This brigade drove the enemy before it, to the crest of the hill; but the rebels were there encountered in much stronger force, protected in a natural rifle-pit formed by a sunken road running in a northwesterly direction. Beyond this, in a corn-field, there was yet another body of rebels; and, as the Union line came forward, a severe fire was poured upon them from the corn-field and from the rifle-pit. When the Federals reached the crest of the hill, volleys of musketry burst from both lines, and the fight raged hotly, and with dreadful carnage. An effort of the enemy to turn the left of the line was met and signally repulsed by the Seventh Virginia, and One Hundred and Thirty-second Pennsylvania Volunteers: on being foiled in this effort, the rebels assaulted the Union front, but were again driven back with severe loss, the Unionists capturing three hundred men and several stands of colors. Another attack was made on the right of French’s division, but was met by the Fourteenth Indiana and Eighth Ohio Volunteers, and by a storm of canister from Captain Tompkins’ battery, First Rhode Island Artillery. The enemy now gave up all attempts to regain this ground; and the division, which had been under very hot fire for more than four hours, and had expended nearly all its ammunition, took position below the crest of the heights which they had so nobly won. During this time, Richardson’s division had been engaged on the left. General Richardson was badly wounded in the shoulder. General Meagher’s brigade fought so as to increase its well deserved reputation for courage, and strewed the ground with the foe, till its ammunition gave out, and its brave leader was disabled by a wound, and by having his horse shot under him. The Irish brigade was then ordered to give place to that of General Caldwell; and the second line was formed by General Brooks’ brigade.
