telling him that we were about to engage in battle, and
he knew his Irish friends would not leave him in such a crisis.
Corcoran and the officers generally wanted to go to the expected
battle, but a good many of the men were not so anxious. In the
Second Wisconsin, also, was developed a personal difficulty. The
actual colonel was S. P. Coon, a good-hearted gentleman, who knew
no more of the military art than a child; whereas his lieutenant-
colonel, Peck, had been to West Point, and knew the drill.
Preferring that the latter should remain in command of the
regiment, I put Colonel Coon on my personal staff, which reconciled
the difficulty.

In due season, about July 15th, our division moved forward
leaving our camps standing; Keyes's brigade in the lead, then
Schenck's, then mine, and Richardson's last. We marched via
Vienna, Germantown, and Centreville, where all the army, composed
of five divisions, seemed to converge. The march demonstrated
little save the general laxity of discipline; for with all my
personal efforts I could not prevent the men from straggling for
water, blackberries, or any thing on the way they fancied.

At Centreville, on the 18th, Richardson's brigade was sent by
General Tyler to reconnoitre Blackburn's Ford across Bull Run, and
he found it strongly guarded. From our camp, at Centreville, we
heard the cannonading, and then a sharp musketry-fire. I received
orders from General Tyler to send forward Ayres's battery, and very
soon after another order came for me to advance with my whole
brigade. We marched the three miles at the double-quick, arrived
in time to relieve Richardson's brigade, which was just drawing
back from the ford, worsted, and stood for half an hour or so under
a fire of artillery, which killed four or five of my men. General
Tyler was there in person, giving directions, and soon after
he ordered us all back to our camp in Centreville. This
reconnoissance had developed a strong force, and had been made
without the orders of General McDowell; however, it satisfied us
that the enemy was in force on the other side of Bull Run, and had
no intention to leave without a serious battle. We lay in camp at
Centreville all of the 19th and 20th, and during that night began
the movement which resulted in the battle of Bull Run, on July
21st. Of this so much has been written that more would be
superfluous; and the reports of the opposing commanders, McDowell
and Johnston, are fa
