I've tried to sort out his service, and this is what I've been able to discern. There are quite a few 8th MSM Cav. scout reports in the Official Records which I've not included here, as they're too lengthy. If you wish me to forward them, send me your email address.

Report of Capt. Milton Burch, Fourteenth Missouri State Militia Cavalry, of
skirmish at Fort Lawrence, Beaver Station, Mo.

SPRINGFIELD, January 16, 1863.

COL.: I submit for your investigation my report of a scout, of which I had
the honor, by permission from Gen. Brown, to command. The object of the
scout was to destroy a powder-mill situated on Crooked Creek, Carroll
County, Arkansas; likewise to break up some parties of guerrillas that were
organizing in the vicinity of the powder-mill.

I started from Ozark on the morning of the 4th of January with 100
men, belonging to the Second Battalion Fourteenth Regt. Missouri
State Militia, for Dubuque, Marion County, Arkansas, by the way of the
Beaver Station, Lawrence's Mill, expecting to get some re-enforcements
there. I proceeded with my command within 4 miles of the post, to rest
my horses and feed. I then proceeded to the station, after resting
and feeding, and requested co-operation of the Enrolled Missouri Militia,
through Maj. [William] Turner, to which he was willing to comply, but,
owing to their provisions not coming in, they could not start with me; but
the major promised to send all the men he could spare, under the command of
Capt. Green, after me to catch up with me that night (4th of January), to
a point on Big Creek, 6 miles from Dubuque, known as the Widow Fisher's, to
which place I proceeded. I there captured 2 rebel prisoners, who gave me
information that a rebel force, 6,000 strong, under the command of Gen.
Marmaduke, had left Dubuque that morning en route for this place. I
immediately dispatched a messenger back to the Beaver Station, with
instructions for Maj. Turner to dispatch forthwith to Ozark. I then started
with my command back to the Beaver Station, expecting to meet Capt. Green
with a re-enforcement of Enrolled Missouri Militia from the Beaver Station,
but did not. As my guide was not very well acquainted with the country and
the roads, I took the main road leading from the Beaver Station, and, Capt.
Green being well acquainted with the country, took a near road and missed
me. I arrived at the Beaver Station about 4 o'clock on the morning of the
6th. I then asked the major if he was in a condition to fall back; he
replied that he had no transportation. I then ordered scouts out on
different roads to give intimation of the enemy's approach. I dismounted my
men for the purpose of resting, as we had not been out of our saddles for
twelve hours, and accomplished a march of 60 miles. I then went to take a
little rest, and see that the boys had everything in readiness for moving
to Ozark, as I was fearful the enemy would reach there before me. I
therefore ordered my men into the saddle again, it being now daylight, and
we started for Ozark. We had not proceeded far before the enemy's infantry
opened upon the picket guard southeast of the station. I then ordered a
halt, with the intention of gaining and occupying the block-house; but
before we could make the point the enemy was in possession of the
block-house and all the ground around the block-house. I then ordered my
men to move by the head of column to the right, under a smart fire from the
rebels. There was also a detached force of the enemy coming up Big Beaver
with the intention of cutting off our retreat. I started for Ozark, leaving
the main road and taking a right-hand road. Hearing that a portion of the
enemy had gone up Little Beaver with the intention of cutting us off from
Ozark, I traveled slowly, using precaution against surprise, and arrived at
Ozark about 10 o'clock of the night of the 6th. I then ordered all the
baggage to be conveyed across the river on the road to Springfield, which
was promptly complied with, and waited for further orders, which orders I
received for us to fall back to Springfield.

Respectfully, your most obedient servant,

MILTON BURCH,
Capt., Cmdg. Company H, 14th Cavalry, Missouri State Militia.

Col. CRABB.

Report of Capt. William C. Human, Eighth Missouri
State Militia Cavalry.

HDQRS. FIRST BATT., EIGHTH MO. STATE MILITIA,
Yellville, Ark., February 12, 1864.

GEN.: I have the honor to make to following report: In obedience
to your orders I marched from Ozark, Mo., on the 18th of January with
all the available men of the First Battalion, Eighth Cavalry Missouri
State Militia. I marched 20 miles to Swan Creek and camped. On the
19th, marched 10 miles south of Whit River. On the 20th, marched to
Baker's Prairie. On the 21st, marched through Baker's and Hussa
Prairies to Marshall Prairie. Had several skirmishes; killed 4 and
wounded 2 bushwhackers. The pickets were firing during the night.
Marched on the 22d up Clear Creek; found about 180 rebels. I formed
two of my companies and drove the rebels across the mountains to the
south side, where they secreted themselves behind the brush and rock
until the column came down through the ravine. They poured a heavy
fire from the top of the mountain down on the main column. I managed
to throw skirmishers on the opposite mountain, and drove them in every
direction; killed 4 and wounded 2. Here I lost 2 horses wounded and
left; also 2 men were very slightly scratched. Camped in the bottom
near the mountain. Marched on the 23d to Lebanon ; fed, and marched
on to Burrowsville. We were fired on from the tops of several hills, but
no damage was done. After having rested for two days, I learned that
there was a force in Clinton. I started about dark, marched 30 miles,
and arrived at Clinton at 4 o'clock on the morning of the 27th, but there
was no force in that country. Moved to Red River, up Red River to
Denton, and back to Burrowsville. On the 31st marched to Bear Creek,
scouted the country; scattered the rebels into small squads. I then moved
to Ring's Mills, near Marshall Prairie; scouted the country for several
days; killed 21 bushwhackers. Here I lost 1 man and 1 scout killed in
a skirmish with a lot of bushwhackers. I then moved to Rolling Prairie;
scouted the country; killed 2 bushwhackers. I was then ordered by
Gen. Holland to this place. I have captured 32 head of horses. I find
plenty of forage, bacon, wheat, and corn meal. The horses are
barefooted, and some of the men need clothing very much.

I have the honor to be, general very respectfully, your obedient servant,

W. C. HUMAN,
Capt. Cmdg. First Batt., Eighth Cav., Mo. State Militia .

Brig. Gen. JOHN B. SANBORN,
Cmdg. District of Southwest Missouri.
