Weber’s Brigade, forming the advance of French’s Division, encountered the enemy near Roulette’s house at about 9:15 A.M., pushed them back to the Bloody Lane and gained a position on the high ground about 60 yards north of this point. Here the Brigade became engaged in an obstinate contest with the enemy which was maintained until, having lost one third of its numbers in killed or wounded, it was relieved by Morris’ Brigade and withdrawn to the vicinity of Roulette’s house where it remained until the close of the day.
