Battle of Bull Run
The regiment advanced by the Warrentown Road and was detatched to guard the road, remaining until around 10 a.m.
General Keyes reported, “The order to advance was given at about ten o’clock A.M., and from that hour to four P.M. my brigade was in constant activity on the field of battle. The First Regiment Connecticut Volunteers was met by a body of cavalry and infantry, which it repelled, and at several other encounters at different parts of the line the enemy constantly retired before us.
“Before recrossing Bull Run, and until my brigade mingled with the retreating mass, it maintained perfect freedom from panic, and at the moment I received the order for retreat, and for some time afterward, it was in as good order as in the morning on the road. Half an hour earlier I supposed the victory to be ours.”
The regiment returned to its campground at Centreville in good order and intended to bivouack for the night, but it was ordered before midnight to continue the retreat to Falls Church.
