In his first combat Lieutenant Frederick M. Yeager led part of Company K, 128th Pennsylvania Infantry in their advance through the East Woods and toward the Dunkard Church on 17 September 1862 at Antietam. He was Captain when he mustered out in May 1863.

He was a professional photographer in Reading, PA from 1864 to at least 1874, and later an “art publisher.” Above is a promotional piece from his studio, online from [Langdon & Langdon’s] Langdon’s List of 19th & Early 20th Century Photographers.
