I stumbled onto a bit more information yesterday on Charles E. Bates, the gentleman from the 4th US Cavalry whose letters are featured here. While cruising through the Heritagequest site (thanks again for the tip, Brian!), I found George S. Burnham’s Record of the service of Connecticut men in the army and navy of the United States during the War of the Rebellion, published by Press of the Case, Lockwood & Brainard Company in Hartford in 1889. Contained within the book were some highlights of Charlie’s career.
He enlisted in Company E on December 30, 1857, listing New Haven as his city of residence. He was promoted to corporal May 1, 1859, and sergeant August 24, 1860. He was reduced to the ranks (private) on October 3, 1860. He was promoted to corporal for the second time on January 1, 1862, and sergeant again on October 25, 1862. He reenlisted as a veteran on December 18, 1862. He was again reduced to the ranks on October 12, 1865. Bates was discharged at the end of his term of enlistment on December 18, 1865.
I also found two more folks from the 6th Cavalry and several from the 2nd. It always nice to find these gems, however accidentally.
