Put up our tents between Forts Ramsay and [Buffalo] at Upton's Hill. On Friday, fighting heard west and southwest of us — supposed to be at Manassas. All day Saturday, ditto. At Alexandria first saw McClellan's Grand Army. They do not look so efficient as General Cox's six regiments, but are no doubt good.
The Thirtieth got here in time to get through to Pope. [The] Eleventh and Twelfth [Ohio] went forward under Colonel Scammon to try to do the same thing. At Bull Run Bridge, beyond Fairfax, united with First, Second, Third, and Fourth New Jersey, under General Taylor, and pushed on, New Jersey regiments in advance; ran into a battery and heavy force of the enemy. New Jersey broke, fled, and never rallied; [the] Eleventh and Twelfth pushed on and fought gallantly, Colonel Scammon cool and steady! Won praise from all. Good! Honor of Ohio sustained. Eastern correspondents fail to tell the facts.
