Gouverneur K. Warren
The V Corps saw action at the Second Battle of Bull Run, fighting on the left wing of the Union army. Losses of the small corps were 331 killed, 1,364 wounded, and 456 missing; a total of 2,151, out of about 6,500 engaged. Two of the corp's six brigades were not engaged and George Morell was temporarily detached, his division being commanded by Brig. Gen Daniel Butterfield. One brigade, composed of two regiments under Gouverneur K. Warren, made a futile stand against the Confederate attack on the Union left flank.
