This excellent CDV of Theodore Burr Gates is from the collection of descendant Piera Weiss who kindly provided us a scanned copy.

Then their Lieutenant Colonel, Gates commanded his regiment in battle on South Mountain on 14 September and at Antietam on 17 September 1862. He was promoted to Colonel soon afterward, and was brevetted Brigadier General of Volunteers in March 1865.

He returned to his law practice after his term expired in late 1864, but also continued in state service and was commissioned Major General in the New York Militia in 1867.

    This is not an image of Colonel Theodore Burr Gates. This is a cdv of Colonel George Henry Sharpe. 120th New York Volunteer Infantry.

    Thanks for the comment, Seward. These men certainly do look a lot alike.

    Here are a couple of wartime pictures of Sharpe, for comparison, from the Photographic History of the War (Vol. 8, 1911) and the Library of Congress, respectively. Although not definitive in itself, you’ll notice Sharpe sported a mustache, but no beard. The same is true in other photos of him from both before and after the war.

    Here’s the man identified as Gates, again, from that CDV, for an easier side-by-side:

    And Gates from an identified photograph, also at the Library of Congress:
