The Twenty-first regiment of Iowa Volunteers was organized at "Camp Franklin,"
near the city of Dubuque in the latter part of August, 1862. One of the companies forming
a part thereof, some two months before, and more, had been mustered into the service at
Clinton, under that special authority of the Department of War, by which as we have
seen, the Eighteenth regiment was authorized. But that regiment being filled by other
companies, this was transferred to the Twenty-first, and became Company A therein. The
other companies were mustered into the service on the 18th, 20th, 22d, and 23d days of
August, Samuel Merrill, of Clayton county, having already been commissioned Colonel,
Cornelius W. Dunlap, of Mitchell, Lieutenant-Colonel, and S. G. Van Anda, of Delaware,
Major, the organization was complete at the date last mentioned. The regiment at this
time had an aggregate of nine hundred and seventy-six men.
That company which had been recruited by special leave of the authorities was
recruited in various counties, but a majority of its members were citizens of Mitchell,
Black Hawk, and Worth. The other companies were from Dubuque, Clayton, and
Delaware, each of which contributed generously to this gallant command—Dubuque
county giving no less than four companies, Clayton three, and Delaware two. So, though
the regiment was not entirely from the Third Congressional District, it was near enough
so to be claimed as belonging thereto. But, happily, the claim was merged in the broader
and better one of the State at large, and the country, for both which, before the men
returned to their homes they did most gallant service, and left behind them in honored
graves mans beloved comrades
6
The Twenty-first halted nearly a fortnight at Iron Mountain, and then marched to St.
Genevieve on the Mississippi, arriving at that post on the 11th of March. there many
furloughs were granted to the sick, and to a number of officers. On the fifth, one wing of
the regiment, under Major Van Anda, embarked on the steamer Groesbeck, and moved
down the river.
It was soon followed by the other wing, and about the 1st of April the regiment found
itself at Milliken's Bend, Louisiana. Here, upon the organization of the army for the
campaign of Vicksburg, the Twenty-first Iowa was assigned to the Second Brigade,
Fourteenth Division, Thirteenth Corps d'Armee, Colonel Harris, Eleventh Wisconsin,
commanding brigade, General E. A. Parr, the division, and General McClernand the
corps.
The line of March was taken up on the 12th, and that night the regiment encamped at
Richmond, Louisiana. But, without relating here particular incidents of this toilsome,
laborious, amphibious march, let it suffice to state that on the last day of the month, the
regiment landed from transports, which had run the batteries of Vicksburg and Grand
Gulf, about fifteen miles below the latter place on the Mississippi shore, having since the
12th undergone labors of great severity, and witnessed spectacles which had never before
passed before the visions of the men— magnificent mansions, now in ruins, surrounded
with shrubbery of a thousand kinds, whose delicious fragrance sweetened the air with a
singular delightfulness; the terrific bombardment of Grand Gulf by the gun-boat fleet,
responded to with equal spirit by the land batteries—the repose, and beauty, and
loveliness of Peace, by the side of grim, horrid War. But General Grant gave his troops
no time to moralize on these contrasts.
General McClernand's corps in the advance, taking time only for the men to place in
their haversacks three days' rations (which were to last a fortnight) pushed on from the
landing at Bruinsburg for the bluffs some three miles back. Reaching the bluffs some
time before sunset, McClernand continued to advance rapidly, hoping to be able by a
forced march to surprise the enemy if he should be found near Port Gibson, and prevent
him from destroying the bridges over Bayou Pierre on the roads leading to Grand Gulf
and Jackson. He did not succeed in surprising the enemy, but his movement very speedily
resulted in the preliminary skirmishing of the first pitched battle of the campaign,
namely,
7
THE BATTLE OF PORT GIBSON.
This was a treble engagement so far as the Twenty-first and some other Iowa
regiments were concerned. The battle was brought on and fought in this manner: Colonel
Harris' brigade had the advance of the column, and the extreme vanguard was the
Twenty-first Iowa regiment. While the column was in rapid motion toward Port Gibson,
and at about ten o'clock on the night of April 30th, Colonel W. M. Stone, Twenty-second
Iowa, was ordered to take command of the brigade, Colonel Harris being sick. Colonel
Stone was instructed to march on Port Gibson as rapidly as possible, and occupy the
several bridges across Bayou Pierre at that place. Four companies of the Twenty-first
Iowa, and one howitzer from the First Iowa Battery, Captain Harry Griffiths, were sent
forward as advance guard. Two of the advance companies, under Lieutenant-Colonel
Dunlap, were deployed as skirmishers, the other two, under Major Van Anda, moved in
support of the howitzer. The remainder of the brigade, the Twenty-first leading, moved in
supporting distance behind, formed in column. The road passed through a country much
broken by gorges and ravines, and supporting a dense forest of tall timber, thick
underbrush, and the cane peculiar to the southern country, the thoroughfare itself running
on a narrow, elevated ridge, or a chain, rather, of ridges of this character, with deep and
impenetrable ravines on either side. I} was over such a road as this, that the Twenty-first
Iowa formed the advance of the grand army, on this night march. The guide who pointed
out the way was an old negro slave.
About four miles from Port Gibson the road divides in two parts, one turning
abruptly to the right the other to the left, but both leading to the town. Near this fork in
the road was a house of worship—Magnolia church. When our skirmishers came to
within about three-fourths of a mile of this church they received the fire of the enemy's
pickets, posted in an angle of the road. Colonel Stone promptly made the proper
disposition of his brigade, and moved forward, ready to deploy into line at a moment's
warning, and with a strong covering line of skirmishers. This was about midnight. The
march continued. As the skirmishers approached Magnolia church they received a heavy
volley of musketry from the enemy, strongly posted both on the right and left of the
church. The advance soon became engaged, and Colonel Stone ordered up the whole
brigade to its support. The howitzer of the First Battery, in the advance, replied to the
enemy, who had now opened with artillery, with great spirit and apparent accuracy,
Sergeant William K. Leebert commanding the pieces The battery, and Klaus' Indiana
Battery, soon opened on the enemy from a ridge in rear of our advance, whereupon there
ensued an artillery battle long to be remembered by those who witnessed it. The fire of
the rebel batteries was quite accurate, and disabled many of our men and horses. The
flashes of the discharges in the darkness of the night, the shells screaming and bursting in
the air, the rattle of grape shot through fences and timber, altogether formed a scene of
more awe-inspiring power than almost any battle-field of the war. At about two o'clock
the firing ceased on both sides as if by mutual consent, and the weary soldiers laid
themselves down upon their arms to sleep. Thus ended the first act in the tragedy of Port
Gibson.
The enemy commenced the battle early on the morning of May 1st, Colonel Stone's
Brigade for some time receiving their fire of artillery, and responding thereto with great
spirit and effect, before other troops were deployed into line. Nevertheless, the sun had
not rose high in the heavens, nor dispelled entirely the morning mist, before Osterhaus
delivered a vigorous attack upon the enemy's right.
The position of the enemy here was well chosen, and it required an hour's severe fighting
to drive him from it. Meanwhile, General Carr, Stone's Brigade in reserve, attacked the
enemy's left, moving over a rugged country, and through almost impenetrable canebrakes,
and presently Stone's Brigade, marching on and to the left of the main road by
Magnolia church, gallantly delivered attack on the rebel left center. The action now
became general, except at the center, where a continuation of fields extending to the front
of McClernand's lines for more than a mile separated the antagonists. Hovey's Division
had gone into the fight, and General A. J. Smith's was holding the center, ready and eager
to join in the combat. Osterhaus' Division held his ground on the left, whilst Carr and
Hovey steadily advanced on the right, capturing many prisoners, two stands of colors,
two twelve-pounder howitzers, three caissons, much ammunition, and placing large
numbers of the enemy hors-de-combat.
But just as we had fairly driven the rebels from their strong position, General
Baldwin came up to the aid of Bowen, the rebel general commanding, with heavy
reenforcements, causing loud shouts along the enemy's lines. Just about this time,
however, General Osterhaus, who had been reinforced by Logan's Division, by a flank
movement and a brilliant charge led by Osterhaus in person, had discomfited the enemy's
right and taken three pieces of his artillery. Wherefore the rebels everywhere fell back,
and the second act was closed, with loud shouts on the part of the Union troops, who
continued to press forward for more decisive victory
The enemy was again found posted in a strong position more than a mile to the rear
of his former lines. Here Hovey and Carr, with a brigade of General A. J. Smith's
Division, and Stevenson's Brigade of Logan's Division, had some difficulty in defeating
the enemy; for our troops had again to move over hills and through cane-brakes under a
heavy fire of artillery and musketry. The battle raged with great fury, first on our right,
where Hovey delivered a fine attack, at length succeeding in enfilading the rebel lines
with his artillery. The combat then surged over to the center, where Carr, and Smith, and
Stevenson had a hot engagement, and in the fierce struggle beat back the enemy, and
gained the day. It was now nearly dark, and as the shades of night closed upon the field
which our troops had won, they took their first real repose since leaving D'Schron's
Landing, more than twenty-four hours before.
The battle of Port Gibson, if not decisive, was a fine precursor of the brilliant
successes which made the campaign of Vicksburg memorable. The Union loss, in killed
and wounded, was eight hundred and forty-eight and five missing, all of which except
about fifty, fell upon the Thirteenth Army Corps. We captured from the enemy five
hundred and eighty prisoners, but his loss in killed and wounded was not ascertained. It
must have been heavy. The rebel historian notes the battle as "the first mistake with
which Pemberton had opened his chapter of disasters," but he is entirely reticent upon the
subject of losses. Reflecting upon the duration and nature of the battle, I persuade myself
that the enemy's losses in killed and wounded were equal to our own, whilst their losses
in materiel and trophies were considerable against absolutely nothing in these respects on
our side.
8
The Iowa regiments of infantry besides that whose history is now under our
immediate consideration which bore a prominent part in this engagement were the
Twenty-second, Twenty-third, Twenty-fourth, and Twenty-eighth, whilst no artillery on
the field performed better service than our First Battery. The Twenty-first, Twentysecond,
and Twenty-third were in Colonel Stone's brigade, as was the battery. The other
infantry regiments named were in Hovey's Division.
9
These commands all fought with as conspicuous gallantry as any men could have
displayed with similar orders to obey. The Twenty-fourth was in support of artillery
throughout the day and lost but few men. The Twenty-eighth, Colonel Connell,
performed similar service much of the time in this its first battle, but three of the
companies supported an Indiana regiment in a charge on a rebel battery, which was taken,
together with many prisoners. The regiment lost quite heavily in wounded. The Twentysecond,
Major J. B. Atherton commanding, was in the thickest of the fight. Adjutant D. J.
Davis, Lieutenants William M. De Camp, D. W. Henderson, and John Francisco, and
many men were wounded, and two killed. The Twenty-third, Lieutenant-Colonel
Glasgow, lost more heavily than any of our regiments engaged. Lieutenant D. P. Ballard
was among the wounded. The First Battery was handled throughout with consummate
skill, and suffered a loss of five men wounded.
Colonel Stone in his official report of the operations of the brigade specially names
Colonel Merrill, Lieutenant-Colonel Glasgow, Major Atherton, commanding regiments,
and Lieutenant-Colonel Dunlap and Major Van Anda, as entitled to praise. He also
mentions Lieutenant Waterbury, of the Twenty-third, acting aid-de-camp, and states,
generally, that the officers and men of the brigade behaved with the utmost coolness and
exhibited a determined courage that would have done honor to any troops. General Carr,
division commander, gratified with the fine conduct of his troops, bestowed praises upon
them in no mincing manner. He spoke in the highest terms of Colonel Stone; of the
Twenty first Iowa, "first in battle and one of the last to leave the field ;" of the Twentythird
Iowa which, "with its gallant commander, behaved admirably;" he mentioned
Lieutenant-Colonel Dunlap, Major Van Anda, Captain Crooke, and Sergeant Kirst, of the
Twenty-first, and passed a glowing compliment upon Sergeant Leebert, in charge of the
howitzer on the advance. In fine, the Iowa commands behaved finely at the battle of Port
Gibson, according to the well established custom of the troops of the State, and received
the just encomiums of their generals.
As for the Twenty-first, though it was under fire as long as any regiment in the field,
it lost none killed, but had seventeen wounded, and two missing among the former
Lieutenant-Colonel Dunlap. 2
On the day after the battle, the regiment marched to Port Gibson and Bayou Pierre,
where the right wing bivouacked, but the left wing, Major Van Anda, returned to Port
Gibson. On the 6th line of march was resumed. Moving nearly to Jackson, the course of
the march was changed directly for Vicksburg. In the battle of Champion Hills, fought on
the 16th, the regiment was posted with the reserve, and was not called into action till near
the close of the combat, when it moved with the command sent out to flank the enemy's
right, but the enemy had put himself in retreat before it gained position, so that
throughout the day it was but slightly engaged.
General Grant pushed rapidly on in pursuit of the rebels, and on the 17th was fought
the battle of Big Black River Bridge—a short but terrible combat wherein the troops
engaged, and especially the Twenty-first and Twenty-third Iowa, displayed a daring
which amounted to heroism, accomplishing invaluable results by a dashing charge, but
leaving many of their men dead and wounded on the field. I shall speak of this action in
my account of the Twenty-third regiment. Let it suffice to state here that Colonel Merrill
was there well nigh mortally wounded, and that the loss of the regiment, out of less than
three hundred engaged, was thirteen killed and seventy wounded.
On the 19th our regiment marched to the rear of Vicksburg and took its position in
line, which very soon became a line of investment. During all the operations which
followed—the sharp-shooting of the 19th, 20th, and 21st; the terrible assault of the 22d;
the siege accompanied by so many labors, discomforts, dangers—the Twenty-first
faithfully, gallantly, patiently performed the duties assigned it. In the assault its bravery
and dash were conspicuous among all the regiments which on that bloody day so bravely
and dashingly marched into the jaws of death. Lieutenant-Colonel Dunlap still suffering
from his wound received at Port Gibson, was unable to lead the regiment in the assault,
and it was commanded by Major Van Anda.
2 The others wounded were: C. E. George, C. D. Hewett, R. H. Cunningham, Charles
Rhul, Daniel Shilling, A. B. Story, W. J. Comstock, John Busby, S. Brenton, Robert
Strain, Isaac St. Hughes, Edward Murray, John Van Kuran, Missing, John Love, I. C.
Thompson.
Dunlap, however, came on to the field as fast as his wound would allow him to walk,
and was killed after the charge had been made. Major Van Anda was wounded during the
charge. Captain Harrison, Captain Greaves, Lieutenants Roberts, Adams, Childs, and
Bates were also wounded, Roberts and Bates mortally, the latter dying in the hands of the
enemy. Out of two hundred and eighty officers and men who took part in the assault, the
regiment lost one hundred and thirteen in killed and wounded.
From the assault until the 3d of July, the regiment remained in the trenches, often
working night and day, advancing the parallels to the enemy's works. The siege was very
fatiguing and confining to the men.
The rebel sharp-shooters in front of this part of our line of investment completely
commanded every portion thereof, so that no man dared to raise his finger above the
works. The troops could hardly stand on their legs, without making targets of their heads.
On the day before the capitulation, the regiment marched toward Warrenton, but in the
evening returned to its accustomed position. On the next day it rejoiced with unspeakable
gladness at the triumph of our arms, and because thereby it was relieved from duties more
irksome than any it had ever been called upon to perform. The Twenty-first, at this time
under command of Captain W. D. Crooke, joined in the movement against Johnston
which immediately followed the victory of Vicksburg, and participated in the siege of
Jackson and the destruction of railways and public property which followed the second
capture of that capital. In the heavy skirmishing which accompanied this campaign before
Johnston evacuated Jackson the regiment lost one man killed and fourteen wounded. The
campaign over, it returned to Vicksburg and remained in encampment there until near the
middle of August, diseases in many forms, the results of the siege, attacking the men and
carrying numbers to the grave.
