I found a couple of excellent accounts which nicely bracket the military career of Captain Samuel A. McKee, 2nd United States Infantry. They are too good not to share and I hope both of my readers will appreciate them.
McKee was commissioned 2nd Lieutenant, USA on 5 August 1861 and First Lieutenant 5 days later.
He led Company I of the 2nd US at Antietam, part of a consolidated battalion of companies from the 2nd and 10th United States Infantry regiments. They crossed the creek over the middle bridge about midday on 17 September 1862 and pushed a line of skirmishers up the pike toward Sharpsburg.
Battalion commander Lieutenant John Poland reported “Lieutenant McKee, commanding Companies I and A, Second Infantry, while deploying to the front, was severely wounded and compelled to leave the field.”
