I’ve appended Colonel Sloan’s after action report of his 4th South Carolina at Bull Run. It’s difficult to follow his actions, but it appears that his initial camp site at Stone Bridge was perhaps a couple of hundred yards to the West of the bridge on Bull Run where Capt. Dean’s Company C was initially left in reserve. This was just North of the turnpike. Exactly to where they later moved I cannot ascertain, but the regiment was well to the West of the bridge and closer to Stone House. I do not believe they were engaged before moving.

Nine positions for the regiment are noted on the map of the battle, found in the Atlas to Accompany the Official Records, Plate No. 5-1.

The first five positions being North of the Warrenton Turnpike with the 5th position being astride the pike on the Northern slope of Henry Hill. The remaining four positions are to the South of the Turnpike on the western slopes of Henry Hill.

Just where he was wounded cannot be identified. However, I would not belive to be in the area of near Stonebridge.

Report of Col. J. B. E. Sloan, Fourth South Carolina Infantry.

HDQRS. FOURTH REGIMENT SOUTH CAROLINA VOLS.,
Stone Bridge, Bull Run, Prince William Co., Va., July 23, 1861.

GENERAL: I have the honor to report that about 3 o'clock a. m. Sunday,
July 21, the officer of the guard awoke me and stated that my picket towards
the stone house reported that he heard commands in the woods beyond, as
if some one was commanding forces. I ordered him to report the same to
you. Towards 4 o'clock I heard the firing of pickets on the opposite side of
Bull Run from my camp, and at once ordered the men to be waked up. In
a few moments afterwards your orders came, ordering me to get ready and
move up on the hill at once. I ordered the men to fall in, and before 5
o'clock formed in line of battle on the left side of the road, covered by an
undulation near the bluff of the hill, about six hundred yards distant from
stone bridge.

I sent out, as ordered by you, Capt. Kilpatrick's company, Calhoun
Mountaineers, to deploy as skirmishers on the left of the bridge, and Capt.
Anderson's company, Confederate Guards, to the right of the bridge, both
of them sending their advance skirmishers to the bank of Bull Run. Capt.
Dean's company and the Palmetto Riflemen, the latter commanded by
Lieut. Earle, was left at the camp, some three hundred yards distant, as
a reserve. The enemy could be seen in the woods opposite. About six
o'clock the enemy sent a man out with a flag, which he attempted to plant
in the road about two hundred yards from the bridge. Capt. Kilpatrick
fired at him five or six shots. The man with the color fled precipitately to the
woods. The enemy's battery, which was planted on the left side of the road
in the edge of the woods, then commenced firing at intervals in different
directions, as if to make us show our position, which was still concealed
from them. Sometimes they would burst a shell about the bridge; again, fire
a ball from a rifled cannon just over us. I could also hear firing of cannon
below. Up to 8.20 they had fired six times towards us.

About 8.30 o'clock you ordered me to get ready and move up on the ridge,
leaving the reserve and the companies sent out as skirmishers. After
advancing one-fourth mile I formed in line of battle on the left of Maj.
Wheat's battalion, he having already formed on the right of the field. Your
cannon formed in our front. I had not occupied this position but a few
moments when, by your orders, I moved a little to the front and about
three-fourths of a mile to the left, and formed in line of battle in a ravine,
my left resting on the pike road leading from stone bridge by Sudley's Mill,
and about two hundred yards in advance of the stone house, and sent out
Capt. Hawthorn's company as skirmishers in the woods, resting on our right.

Maj. Wheat's battalion, which had been left with the cannon, advanced in
front of the woods and was fired into by my skirmishers, which was returned
by Maj. Wheat's. My skirmishers sustained no loss, but wounded two of
Maj. Wheat's men. My skirmishers then returned, both Maj. Wheat and
Capt. Hawthorn having discovered the mistake. Maj. Wheat at once
opened fire on the enemy and kept it up vigorously for about five rounds. I
sent Capt. Hawthorn to assist him as soon as he returned. I ordered the
cannon to open on the enemy, who had commenced filing out in large force
to our left. I then ordered the battalion to open fire by company, and then
moved up to the left and advanced through the woods to the field in front.
Maj. Wheat having rallied part of his forces and formed on my left, at that
time Gen. Bee came up on my right and advanced part of his force on my
right and commenced a vigorous fire. At the same time I sent forward part
of Capt. Hollingsworth's company as skirmishers. I had the fence pulled
down to charge to the front when the skirmishers and Gen. Bee's forces
advanced to the right. Maj. Wheat at the same time advancing on the left,
the enemy's battery and musketry opened on us in large force, which was
returned, principally directed about the center of the regiment. The regiment
retired to the rear of the woods. Capt. Shanklin rallied his company
around the colors until the entire force had left the ground. I discovered the
enemy attempting to flank us in large force, to which I called the attention
of Gen. Bee, who, seeing the force, said that we had better retreat and
form on the opposite side of the hill, after which re-enforcements came up
and the engagement became general.

Lieut. Earle, commanding Company B (Palmetto Riflemen), and Capt.
Dean's company (C), both reserves, occupied the position first held by the
regiment (on the left of the road near the bridge) until after the battery
retired, when they also retreated toward Lewis' house and were then formed
into a battalion, with portions of Capt. Shanklin's company, under
Lieut. Cherry, and Capt. Long's company and the New Orleans
Zouaves, Capt. -----, and some Alabamians, under Maj. Whither and
Col. Thomas, of Maryland, and by them led to the field of battle on our
extreme left. They charged a battery of the enemy, and, after a severe
conflict, repulsed him. Sergeant Maxwell planted the colors of the Fourth
Regiment South Carolina Volunteers on the cannon of the enemy and
maintained his position until after his comrades had been repulsed by a
superior force, who had deceived our men and prevented their firing upon
them by using our colors and sign of recognition. During this contest Maj.
Whitner had his horse shot under him while endeavoring to rally the men led
to the charge. Capt. Kilpatrick held the position on the left of the bridge
until the enemy advanced in large force to the left and near the bridge, when
he left and attached his company to Col. Hampton's Legion. Capt.
Anderson remained on the right side of the bridge till near 1 o'clock, when
the retreated toward Lewis' house and then formed on some forces said to
be under command of Ex-Governor Smith, and advanced with them into the
field, engaged the enemy's battery, when the forces under command of
Col. Thomas and Maj. Whither came up, when he united with them in
a charge on the battery which is above mentioned, in which our colors were
planted on the cannon, but afterwards repulsed. I rallied the other remnants
of companies on Capt. Kilpatrick's company on the right of Hampton's
Legion and led them up to three different advances. Afterward the men under
my command worked the battery under the direction of Capt. Ferguson, aide
to Gen. Beauregard, who made several telling fires on the enemy, assisted by
Lieut. Sloan, commanding fragments of companies.

Capt. Kilpatrick behaved most gallantly, and was shot through the sword
hand while bravely cheering his men onward. His first lieutenant, Horton,
was shot in the head in a charge. Lieut. Hunt, of Company H, deserves
particular credit for his bravery in reorganizing the company. Sergeants
Hawthorne and Fuller both acted their part well; the former was exceeded
in gallant daring by no one. Capt. Anderson sustained his character as an
officer. Many of the officers and soldiers behaved well, among whom were
Capt. Holingsworth, Corporal Williams, Privates Ferguson, Smith, and
Wilkinson, of Company I. The Palmetto Riflemen were very efficient and
behaved well. Lieut.-Col. Mattison was active in my assistance
during the day in encouraging the men to do their duty. Capt. Pool and his
second and third lieutenants were all seriously, if not mortally, wounded.

Very respectfully, your obedient servant,

J. B. E. SLOAN,
Col. Fourth Regt. S. C. Volunteers.

Gen. N. G. EVANS.
