Chickamagua after battle report:

Report of Col. Samuel K. McSpadden, Nineteenth Alabama
Infantry.

HDQRS. NINETEENTH ALABAMA REGT.,
Missionary Ridge, Tenn., October 5, 1863.

CAPT.:In obedience to orders from brigade headquarters, I have
the honor to forward a report of the part taken by my regiment
in the late battle of Chickamauga:

Having marched from La Fayette, Ga., on the night of the 17th
and morning of September 18, we were placed in line of battle
near Lee and Gordon's Mills, where we lay under occasional
shelling, with skirmishing in front, until (Saturday evening, 19th)
we were marched by the right flank some 2 miles across
Chickamauga Creek and again placed in line of battle. Here we
bivouacked during the night.

Early on Sunday morning (the 20th), we were ordered forward,
and about 8 a. m. took position behind some temporary
breastworks of logs, chunks, &c. My skirmishers were hotly
engaged with those of the enemy at this point, while I lost
several men killed and wounded by shell and canister along my
line. Those works were in open
woods of heavy timber, with like timber and thick
undergrowth in front for some 200 yards to an open field.

About 11 a. m. we were ordered forward. Scaling our
breastworks, we advanced in good order, driving the enemy from
the woods and across the field, but upon rising a hill in the field
some 50 to 75 yards from its farther boundary, we were met by
a volley of musketry from the enemy, who had been securely
placed behind breastworks in the edge of another woods. At the
first fire of the enemy, so unexpected and near, my regiment
exhibited a momentary hesitancy and wavering, but upon my
ordering "charge," it moved at double-quick, and, with a shout
scaled the enemy's works, and pursued their panic-stricken and
shattered ranks through the woods and undergrowth until,
reaching the borders of another open field, the enemy were
discovered behind some houses, potash-works, and rail
breastworks. At this point there was not even a momentary
hesitancy, but with an increased shout and rapidity of step, we
drove the enemy from these works with great slaughter, and
pursued them through the open field some 250 yards to an
elevated skirt of heavy open woods, where we again came upon
him and drove him in utter confusion from two pieces of artillery
and other breastworks. There being no horses near, we were
compelled to leave the pieces of artillery on the ground. Just
here, the Fifteenth Alabama Volunteers, who were to the right of
my rear, began a heavy enfilanding fire upon me. I immediately
discovered they were friends, and ordered my colors back to the
edge of the open field, and waving them, discovered to the
Fifteenth Alabama their error, upon which they came up by a
left-oblique march in fine order, and, joining in with my
regiment, we continued to pursue the enemy for some distance
across fields, woods, roads, and hills, until we passed over the
telegraph road of the enemy into the hills, where we passed also
other pieces of artillery, and found we had utterly cut the
enemy's cavalry lines asunder.

At this point, I was advised that the enemy's cavalry were
flanking me on the right. I immediately ordered one or two of
my right companies to wheel to the right and engage the cavalry.
The first company had only time to wheel and give two volleys
when the cavalry fled in a panic. Seeing Maj.-Gen. Hindman
some hundred yards to my left, I ran and informed him of the
attempt to flank me. He ordered me to retire by the right flank
to a ravine in the rear, and await the return of the other troops
of the brigade, who had gained a short distance to the front
during my attack on the enemy's cavalry. This charge could not
have been over a less space than 1 1/2 miles, and yet so fierce
and rapid was each successive assault and pursuit the whole time
occupied could not have been over one to one and a half hours.
My loss was very heavy in killed and wounded, and all along the
route the enemy lay dead and wounded, while scores of prisoners
passed to the rear, whom I ordered to report to our provost
guard.

Having been engaged with McCook's corps in the morning (as
we were informed), we reformed with the other regiments of the
brigade early in the evening and were ordered to another part of
the field on our right, to charge a battery of two guns, strongly
supported by infantry, said to be of Gen. Granger's command.
After a desperate charge over the crest of a very steep and rocky
hill, we found our number too small to contend against such
great odds, and fell back to reform and gather momentary breath.
Again we made a charge, determined, if possible, to carry our
standard to
complete victory; but just at the moment we were hoping
to succeed, the troops on our right gave way,leaving my regiment
alone ascending the last point within 40 or
50 yards of the enemy's cannon. Immediately I discovered my
right wing falling back, squad by squad, against every effort that
could be made, until finally my force was reduced to so small a
number it became madness to strive longer, and we were again
forced to retire across the hill. Yet again we reformed our line,
and making the third advance found the enemy and their artillery
had left the field to us. Thus ended the day and its terrible battle.

I was then ordered on picket with my regiment, where, during
the night and next morning, we were enabled to gather about 50
prisoners, two or three wagons of rations, ammunition, &c., with
one piece of artillery, and many small-arms, all of which were
turned over and brought away by the proper officers.

My regiment entered into battle with about 469 guns. My loss
was: Killed, 34; wounded, 158; missing, 12. Total loss, 204.

My regiment deeply mourns the loss of many gallant comrades,
and especially of a good man, a consistent Christian, and
excellent officer, in the person of First Lieut. Joseph B. High,
Company H, who was in command of and fell while gallantly
leading his company at the enemy's third breastworks.

I am much indebted to the universal gallantry and soldierly
bearing of every officer in the regiment, and with the men also,
with the few exceptions of stragglers, whose names I shall report
in a separate communication.

While I cannot specify the many acts of gallantry and daring
exhibited by the different officers and men under my command,
there was one instance of valor and daring so extraordinary as to
demand my attention. On the second charge in the evening, when
the troops on my right gave way and my right wing began to
waver, Capt. Hugh L. Houston, Company B, sprang to the
colors, and, rushing with them to within 30 steps of the enemy's
cannon, gallantly waved them and urged the men of follow their
country's banner. But finding he was supported by only 40 or 50
men, they were compelled to retire, which they did in good
order.

I am, captain, very respectfully, your obedient servant,

SAM. K. McSPADDEN,
Col., Comdg. Nineteenth Alabama Volunteers.

Capt. E. F. TRAVIS,
Assistant Adjutant-Gen.
