During a charge made by a portion of the Ninth Corps on the 17th I was ordered by the brigade commander to move my regiment forward. In the execution of this order the regiment moved out of its breast works in line of battle and making a half-wheel to the right occupied a rise of ground in front of the enemy's earth-works, commanding the rebel works, for two hours and a half and expending 160 rounds of ammunition per man. While all did well, i beg leave to make special mention of First Sergt. R. H. Chase, Company C, for his bravery and coolness throughout this action. There times through the heavy fire he carried communications to the brigade commander and with his own hands brought cartridges from the breast-works to his regiment.
