Lieutenant Ramsay is wearing a single breasted frock coat that has an exaggerated taper at the waist. His forage cap (kepi) has a pair of crossed cannons with number one in the center. His trousers are dark and may predate the change to light blue.
First Lieutenant Andrew Douglas Ramsay was a son of Captain William Ramsay, U.S. Navy. He was commissioned a second lieutenant in the First Artillery June 7, 1855. On the eve of the Civil War he served at Fort Duncan, Texas under then Captain William H. French. He was promoted to first lieutenant on February 25, 1861 and left Texas on the S.S. Daniel Webster on March 19, 1861. Fate decreed a soldier's death for Ramsay who was killed in action July 21, 1861 while second in command of the unfortunate Ricketts' Battery during the battle of First Bull Run (Manassas). This unit, also known as Battery "I" of the 1st U.S. Artillery Regiment, consisted of six 10-pounder Parrott rifle guns and was commanded by Captain James B. Ricketts. Ricketts' and Griffen's batteries were posted on Henry Hill, which became the epicenter of the battle. Confederate infantry of Jackson's brigade were mistaken for friendly forces and were able to close with the batteries and devastate them. Ramsey was killed by a Confederate sharpshooter while gamely trying to recover the guns of the wrecked battery during a Union counterattack.
