On the Campaign

It was not long before the several companies of the regiment were sent to different parts of the field of battle, some to support batteries, some to picket and cover roads on the flanks, some to prevent straggling from the infantry line of battle, and some to act as orderlies and escorts, Company M being detailed to report to General Hooker personally for the latter purpose. Captain Frank W. Hess, of Company M, and Lieutenant Edward M. Heyl, of Company I [sic], particularly distinguished themselves by rallying and leading back to their guns some of our artillerymen whose batteries were in imminent danger of being captured.
