along quaker road, across rowanty creek at the lewis farm, chamberlain's men encountered brigades of confederate brigadier generals henry a. wise, william henry wallace and young marshall moody which had been sent by corps commander lieutenant general richard h. anderson and his division commander major general bushrod johnson to turn back the union advance. a back-and-forth battle ensued during which chamberlain was wounded and almost captured. chamberlain's brigade, reinforced by a four-gun artillery battery and regiments from the brigades of colonel and brevet brigadier general edgar m. gregory and colonel and brevet brigadier general alfred l. pearson, who was later awarded the medal of honor, drove the confederates back to their white oak road line. casualties for both sides were nearly even at 381 for the union and 371 for the confederates.
