Army of Georgia
Charles Winegar was promoted to the rank of captain on May 3, 1864, and he took command of Battery I, First New York Artillery with its six three-inch rifled guns. (Captain Michael Wiedrich had been assigned to a heavy artillery regiment; and Nicholas Sahm, his successor, had died.) This unit also was part of XX Corps, which eventually became a part of the Army of Georgia under Major General Slocum. In that corps, Winegar’s battery served in the Atlanta Campaign, Sherman’s March to the Sea and the Carolinas Campaign. It was assigned to Williams' division until all XX Corps batteries were combined into an artillery brigade under Major John A. Reynolds during the Atlanta Campaign.
