William S. Clark
Burnside at this time ordered his reserve, the Third Brigade, into the line to support Reno's Second Brigade. The 4th Rhode Island replaced the 21st Massachusetts, which had used up its ammunition. While trading places, Colonel Isaac P. Rodman of the 4th Rhode Island was told by Lieutenant Colonel William S. Clark of the 21st Massachusetts that he thought that another attack on the brick kiln would be successful. Rodman sent a courier to General Parke informing him that he was taking responsibility, then formed his regiment and ordered them to charge. Armed with better knowledge of the enemy, this charge was successful. The 4th Rhode Island captured nine brass field pieces, and found themselves in rear of the Rebel entrenchments.
