Antietam Units at First Bull Run

As we observe the 150^th anniversary of the First Battle of Bull Run, I wanted to acknowledge the role that Union and Confederate units and leaders from Antietam, played at that earlier battle. I will try to describe that role in a series of posts over the next several days.

Below is a list of Union regiments and artillery batteries that were present at both the First Battle of Bull Run and the Battle of Antietam. I used the compilation of the First Bull Run Order of Battle found in The Maps of First Bull Run by Bradley M. Gottfried (El Dorado Hills: Savas Beatie, 2009). There are a total 52 infantry regiments listed. This includes those that did not see any action on the day of battle. Of these, 19 would fight fourteen months later during the Maryland Campaign. That’s about 37%. On the artillery side, there are 11 artillery batteries at First Bull Run. All but two are regular army formations. Six of these batteries would see action at Antietam as well.

The list below is the Order of Battle for McDowell’s Army of Northeastern Virginia. Broken out by division and brigade, it only lists the Antietam regiments within these brigades. In parentheses is the assignment of those units at the Battle of Antietam.
