Grant.

It was on this march in the Carolinas that General Sherman sent for me

to come to army headquarters. We were two days away from Columbia. I was

ashamed to go in my prison rags, so I waited. The next day the request

was repeated, and Major Nichols of the staff came and said, "But you

must go, it is an order." And I went. The General was sitting by a

little rail fire in front of his tent, reading a newspaper, when we

approached his bivouac in the woods. I was introduced. He at once told

me how pleased he had been with my song, that I had written in prison

about his army. Devine had given him a copy at that time when he halted

his column to greet us by the door-step at Columbia. "Our boys shall all

sing this song," he said; "and as for you, I shall give you a position

on my staff. Tomorrow you will be furnished a horse and all that you

need; and you must mess with me."

It would be very hard to express my feelings at this sudden transition

from a prisoner in rags to a post at the headquarters of the great

commander. I was almost overcome, but General Sherman's extreme kindness

of manner and speech at last put me partly at my ease. Shortly a big

colored man, in a green coat, announced dinner. "Come," said the

General, pushing me ahead of him into a tent, where a number of

handsomely uniformed staff officers stood around a table waiting his

approach. I was still in my rags. I could not help noticing the curious

glances of the fine gentlemen, who doubtless were wondering what General

Sherman had picked up now.

My embarrassment was extreme. The commander however soon told them who I

was, gave me the seat at his right hand, and almost his entire

conversation at the table was directed to me. The officers of the staff

quickly took the General's cue, and I was soon an object of interest,

even to them.

He directed a hundred questions to me as to the general treatment of

war prisoners in the South, and he, as well as the staff, interested

themselves in all the details of my escape. Telling the story very soon

relieved me of my embarrassment as to my clothes. The horrible tales of

Southern prison pens, however, was nothing new to General Sherman, for

he related to me some of the awful things he had heard of Andersonville

while his army was at Atlanta.

"At one time," said he, "I had great hopes of rescuing all of them at

one quick blow. I gave General Stoneman a large body of cavalry, with

directions to raid down about Macon. This raid was to go farther, and,

by a quick, secret dash capture Andersonville and release every prisoner

there. It was a chance to do the noblest deed of the war, but it all

failed miserably. Stoneman had not fully obeyed orders, and, instead of

releasing a whole army of suffering captives, he got captured himself,

and, with him, a lot of my best cavalry."

It happened that I saw General Stoneman the very day he was brought to

the prison. My narrative of how by desperately bold and violent cursing

he denounced and defied his captors, and everything in Rebeldom, greatly

amused Sherman and all at the table.

Stoneman's awful language and flashing eyes did indeed fairly

intimidate the officer in charge. Evidently he thought he had captured a

tiger. It was a wonder Stoneman was not killed.

The conversation about the prisoners continued. Twenty-five thousand of

them were starving and dying in Andersonville. "It is one of the awful

fates of war," said the General. "It can't be helped; they would have

been better off had all been killed on the battlefield; and one almost

wishes they had been." After a pause, he continued. "At times, I am

almost satisfied it would be just as well to _kill all prisoners_." The

remark, to me, a prisoner just escaped, seemed shocking. I am sure he

noticed it, for he soon added: "They would be spared these atrocities.

Besides, _the more awful you can make war the sooner it will be over_."

It would, after all, be a mercy.

"_War is hell, at the best_," he went on, half in anger, and using an

expression common to him.

For the moment I thought him heartless, but other remarks made to me,

and to the staff, soon told us that whatever the cruelties imposed on

him as a commander, they were executed with heart-pain and only as plain

duty for the salvation of his own army. He even talked of how glad he

would be to be out of the whole bloody business, once the Union were

restored. But if the rebellion continued all his life, he would stay and

fight it out.

When the dinner was over each looked about him to find some garment to

give me. This one had an extra coat, that one a pair of trousers, and

another one a hat. In short I was quickly attired in a rather

respectable uniform.

This matter was just about ended when a beautiful woman was conducted to

Sherman, to ask protection for her home, that was in his line of march.

She was "true blue Union," despite her surroundings. In a moment the

whole atmosphere about the tent was changed. The red-handed warrior, who

a moment before was ready to kill even prisoners, suddenly became the

most amiable, the most gallant and knightly looking man I ever saw.

Beauty, that can draw a soldier with a single hair, had ensnared the

great commander. He had become a gentle knight. The whole army if need

be, would stand stock still to do her one little favor. I now recall how

long after the war I noticed a hundred times this perfectly knightly

gallantry of Sherman toward all women.

This one particular woman seemed a hundred times more beautiful, more

fascinating, there in the green wood alone, with an army of a hundred

thousand strangers about her, when, pointing her hand toward a great

banner that swung in the wind between two tall pines, she smiled and

cried: "General Sherman, THAT IS MY FLAG TOO." There was a clapping of

hands from all of us, and any one of us would have been glad to be sent

as the protector of her home.

The great army was now marching, or rather swimming and wading, in the

direction of Fayetteville, N. C. There were heavy rains and the country,

naturally swampy, was flooded everywhere. I soon learned from the staff

where the army had already been. After the end of the march to the sea

and the capture of Savannah, Sherman had started in with sixty thousand

men, to treat South Carolina in the manner he had treated Georgia--march

through it and desolate it. His proposed march northward from Savannah

was regarded by the Southern generals as an impossibility. The obstacles

were so great as to make it a hundred times as difficult as his march

from Atlanta to the sea. But he led a great army of picked veterans,

accustomed to everything, whose flags had almost never known defeat.

Their confidence in their general and in themselves was simply absolute.

So far, in their march from Savannah they had hesitated at nothing.

It was midwinter, and yet that army had often waded in swamps with the

cold water waist deep, carrying their clothes and their muskets on their

heads. Half the roads they followed had to be corduroyed, or their

horses would all have been lost in the bottomless mire and swamps. Often

their artillery was for miles pulled along by the men themselves, and

that in the face of the enemy, hidden behind every stream, and ready to

ambush them at every roadside. Over all these infamous wagon roads,

across all these bridgeless rivers and endless swamps, our army now

dragged with it a train of sixty-nine cannon, twenty-five hundred

six-mule wagons, and six hundred ambulances. The tremendous obstacles

they encountered before reaching Columbia they were again to encounter

beyond. Not a bridge was left on any creek or river in the Carolinas.

Roads were built of poles and logs through swamps ten miles wide.

Sherman's army had few rations and no tents. The foragers brought in all

the food they could pick up near the line of march. The little rubber

blankets the soldiers carried were their sole protection from storm.

They were almost shoeless. There were not a dozen full tents in the

army. Officers used tent flies sometimes, but oftener simply rolled

themselves up in their blankets, as their men did. At army headquarters

we had but one large tent, used generally for dining under; so we

usually slept in deserted cabins at the roadside.

I recall one fearfully stormy night when the General and his staff had

all crept into a little church we found in the woods. The General would

not accept the bit of carpet one of us had improvised into a bed for him

on the pulpit platform. "No," he said, "keep that for some of you young

fellows who are not well." He then stretched himself out on a wooden

bench for the night. I think he never removed his uniform during the

campaign. Day and night he was alert, and seemed never to be really

asleep. We of the staff now had little to do save carrying orders

occasionally to other commanders.

General Sherman did most of his own writing, and he wrote a rapid,

beautiful hand. We had breakfast by the light of the campfire almost

every morning, and were immediately in the saddle, floundering along

through the mud, always near to, or quite at, the head of the army. At

noon we always dismounted and ate a simple lunch at the roadside,

sometimes washed down by a little whisky. Now and then some one of the

army, recognizing the General riding past, would give a cheer that would

be taken up by brigades and divisions a mile away. There seemed to be

something peculiar about this Sherman cheer, for soldiers far off would

cry out: "Listen to them cheering Billy Sherman."

On the 3d of March we took Cheraw, and twenty-four cannon, also nearly

four thousand barrels of gunpowder. That day General Logan, General

Howard, General Kilpatrick, General Hazen, and many other notables came

to headquarters. There was a jolly time of rejoicing.

Here General Logan, who could play the violin, entertained them by

singing my song of "Sherman's March to the Sea," accompanying his voice

with the instrument. A dozen famous generals joined in the chorus. After

the singing, Logan insisted that I should also recite the poem. I did

so, meeting with great applause from the very men who had been the

leaders in the great "March." Alas! save one or two, they are now all

dead.

Among the captures that day had been eight wagonloads of fine, old wine.

It was now distributed among the different headquarters of the Union

army, and as a result some of the said headquarters were pretty nearly

drunk. One of our staff, at dinner the next day, attempted to explain

his condition of the day before. "Never mind explaining," said General

Sherman crustily, and without looking up, "but only see that the like of

that does not happen again; that is all." That staff officer was a very

sober man the rest of the campaign.

While we were lying there in Cheraw we heard an awful explosion; the

very earth shook. I supposed it to be an earthquake until a messenger

brought word that a lot of captured gunpowder had exploded and killed

and wounded twenty soldiers.

As we were crossing on our pontoons over the Pedee River at Cheraw I

noticed a singular way of punishing army thieves. An offender of this

kind stood on the bridge, guarded by two sentinels. He was inside of a

barrel that had the ends knocked out. On the barrel in big letters were

the words: "I am a thief." The whole army corps passed close by him. An

occasional man indulged in some joke at his expense, but the body of

soldiers affected not to see him. The day we entered Cheraw General

Sherman and his staff rode through the country alone for ten miles,

going across from one column to another. It was a hazardous ride, as the

whole country was full of guerrillas. But nothing of note happened to

us.

On the 8th of March the headquarters staff was bivouacked in the woods

near Laurel Hill. The army was absolutely cut off from everywhere. It

had no base; it was weeks since Sherman had heard from the North or

since the North had heard from him. Now he resolved to try to get a

courier with a message through to Wilmington, at the seaside. An

experienced spy by the name of Pike was selected to float down the Cape

Fear River to ask the commander to try to send a tugboat up, to

communicate with the army. I did not know then that the next one to run

down Cape Fear River would be myself.

In four days we had taken Fayetteville and its wonderful arsenal, built

years before by the American people, and where now half the war supplies

of the Rebel army were made.

When the General and his staff first rode into Fayetteville headquarters

were established in the arsenal. The General, wishing to look about the

town for an hour or so, left me in charge. The other officers rode away

with him. Very shortly a well-dressed, fine-looking old Southerner came

to me and complained that his home was being disturbed by some of our

soldiers. He was, he said, an old West Point friend of General

Sherman's. While waiting the return of the commander, he regaled me with

incidents of their early days together in the North and with his

intimacies with one who would now doubtless be overwhelmed with joy at

seeing him. He begged me to observe what would be his reception when the

General should come. Impressed by his conversation, I at once sent a

soldier or two to guard his home.

Shortly after General Sherman rode in through the arsenal portal and

dismounted. The Southerner advanced with open arms, and for a moment

there was a ray of pleasure illuminating Sherman's face. Then he went

and leaned against a column, and, turning to the Southerner, said, "Yes,

we were long together, weren't we?" "Yes," answered the Southerner,

delighted. "You shared my friendship, shared my bread, even, didn't

you?" continued Sherman. "Indeed, indeed!" the Southerner replied, with

increasing warmth. The General gave the Southerner a long, steady,

almost pathetic look, and answered, "You have betrayed it all; me, your

friend, your country that educated you for its defense. You are here a

traitor, and you ask me to be again your friend, to protect your

property, to send you these brave men, some of whose comrades were

murdered by your neighbors this very morning--fired on from hidden

houses by you and yours as they entered the town. Turn your back to me

forever. I will not punish you; only go your way. There is room in the

world even for traitors." The Southerner turned ashy white and walked

away from us in silence. Sherman sat down with the rest of us to our

noonday lunch. We sat about the portal on stones, or barrels, or

whatever happened to answer for seats. The General could scarcely eat.

Never had I seen him under such emotion; the corners of his mouth

twitched as he continued talking to us of this false friend. The hand

that held the bread trembled and for a moment tears were in his eyes.

For a little while we all sat in silence, and we realized as never

before what treason to the republic really meant. The General spoke as

if he, nor we, might ever live through it all.

Very soon General Howard rode in to complain anew of the outrages

committed on our troops by men firing from windows as they passed along

the streets. Two or three soldiers had been killed. "Who did this

outrage?" cried Sherman, in a loud and bitter voice, "Texans, I think,"

answered General Howard. "Then shoot some Texan prisoners in

retaliation," said Sherman sternly. "We have no Texans," replied Howard,

not inclined, apparently, to carry out the serious, but just order.

"Then take other prisoners, take any prisoners," continued General

Sherman. "I will not permit my soldiers to be murdered." He turned on

his heel and walked away. Howard mounted and rode into the town. What

happened, I do not know.

On Sunday morning General Sherman asked me to take a walk with him

through the immense arsenal of Fayetteville before he should blow it up.

We were gone an hour, and I was surprised at his great familiarity with

all the machinery and works of the immense establishment. He talked

constantly and explained many things to me. Never more than at that time

was I impressed with the universal knowledge, the extraordinary genius,

of the man. There seemed to be nothing there he did not understand. On

our way back to headquarters I heard him give the order to destroy

everything, to burn the arsenal down, blow it up, to leave absolutely

nothing, and he added the prayer that the American government might

never again give North Carolina an arsenal and forts to betray. He was

very angry now at those who had used the United States property in their

desire to destroy the government itself. He had seen nothing in the war

that seemed so treasonable, unless it was the base ingratitude of those

who entered the service of the Rebellion after having been educated at

West Point at the Government's expense.

Pretty soon he said to me: "If I can get any kind of a boat up here, I

am going to have you try to reach Wilmington with dispatches." Almost at

that minute a steam whistle sounded in the woods below us. "There it

is," said the General joyfully. "Pike got through." Very soon someone

came running to say a communication had come from the seashore; a little

tug had run the Rebel gauntlet all the way from Wilmington.

We went in to lunch and the General announced to the staff his intention

of sending me down the river, and off to General Grant with dispatches.

This chance to get word of his movements and his successes to General

Grant and the North was of vast importance, and it moved him greatly. He

left his lunch half finished and commenced writing letters and reports

to the commander-in-chief. That evening at twilight General Sherman

walked with me down to the riverside where the little tug lay waiting.

"When you reach the North," he said, putting his arm around me, "don't

tell them we have been cutting any great swath in the Carolinas; simply

tell them the plain facts; tell them that the army is not lost, but is

well, and still marching." So careful was I as to his injunctions, that

even the newspapers at Washington never knew how the great news from

Sherman reached the North.

I did not know then, starting down the river with my message, that it

was to be seven years before I was again to see the face of my beloved

commander.

The Cape Fear River was flooded at this time, a mile wide, in places

even more, and though its banks were lined with guerrillas there could

not be great danger, if we could stay in the middle of the stream,

unless our little boat should get wrecked in the darkness by floating

trees or by running into shallow places. The lights were all put out.

The pilot house and the sides of the boat were covered by bales of

cotton, to protect us against the Rebel bullets. My dispatches to

General Grant were carefully sewed up inside my shirt, and were

weighted, so that I could hastily sink them in the river should we be

captured. A half dozen refugees from Columbia joined us. Among them was

the Mrs. C----, whose property Devine and I had tried to save the night

of the fire. It was a curious and dangerous voyage down that roaring,

flooded river for a woman to be undertaking in the darkness, but this

woman had now undertaken many dangers. Another of my companions on that

strange voyage was Theodore Davis, a corresponding artist of _Harper's

Weekly_. We kept the boat in the channel as far as we could guess it,

and, for the rest, simply floated in the darkness. We went through

undiscovered; not a shot fired at us. Before daylight, so swift had been

the current, we were in Wilmington.

General Terry had just taken Wilmington and was in command of the city.

Some of my dispatches were for him. He was still in bed, in one of the

fine residences of the place, but instantly arose and urged me to jump

into bed and get some rest while he should arrange to get me immediate

transportation to Grant. I slept till nine, and when I came down to the

drawing-room, now used as headquarters, General Terry asked if perhaps

it were I who wrote the song about Sherman's March from Atlanta seaward.

It had been sung at the theater the night before, he said. I was much

gratified to have him tell me that the whole army had taken it up. "Tens

of thousands of men," he said, "were singing it." I knew, as already

told, that an exchanged prisoner had brought the song through the Rebel

lines in an artificial leg he wore, but it was an agreeable surprise to

now learn of its sudden and tremendous success.

General Terry impressed me as the handsomest soldier I had seen in the

army--McPherson, the commander of my own corp, only excepted. He was,

too, a refined and perfect gentleman. Looking at him I thought of the

cavaliers of romance. Here was real knighthood, born and bred in the

soil of the republic. The laurels for his heroic capture of Fort Fisher

were fresh on his brow.

Before noon an ocean steamer, the _Edward Everett_, was ordered to take

me at once to Fortress Monroe. Two of my army friends went along. The

captain, leaving on so short notice, had provided his ship with

insufficient ballast, and to me, a landsman, the vessel's lurchings were

very astonishing. I had never seen the ocean before, and it was not long

till I wished I might never see it again. To add to my alarm, a fierce

tempest sprang up as we passed around Cape Hatteras, and the danger was

no longer imaginary, but very real. The few passengers on the boat might

as well have been dead, so far as any self-help was to be thought of in

case of disaster. Even the captain was very seasick, and, altogether,

passengers and crew were badly scared. For many hours it was nothing but

a fierce blow and a roll about on the mad waters. All things come to an

end; so did this storm, and at last we reached Fortress Monroe, where I

was hurriedly transferred by some sailors in a yawl over to a boat that

had already started up the James toward Richmond. Our captain had

signaled that he had a dispatch bearer from the Carolinas. We had not

gone far until we passed the top of a ship's mast sticking a few feet

above the water. It was the mast of the _Cumberland_, that had gone down

in her fight with the _Merrimac_ with as brave a crew as ever manned a

war boat.

The steamer I was now on was crowded with officers in bright uniforms,

apparently returning to their regiments. I wondered if all the Eastern

army had been home on a furlough. I could not help contrasting to myself

this ship full of sleek, brightly uniformed officers with the

rough-clad soldiers and officers of the army of Sherman. Sherman's

foragers and veterans of the March to the Sea might have cut an awkward

figure alongside these gay youths just from Washington.

In the afternoon the ship came to at City Point, and I climbed up the

bank of the river bluff for perhaps a hundred feet, and was soon

directed to the headquarters of the commander-in-chief of the United

States armies.

When I reached the open door of Grant's famous little cabin a young

officer asked me to come in, and was introducing me to the chief of

staff, Rawlins, who stood there with some letters in his hands. That

instant General Grant showed his face at the door in the back of the

room. I knew who it was at once. He stepped forward to where General

Rawlins was speaking with me, listened to the conversation a moment, and

without any formal introduction, smiled, took me by the hand and led me

into the back room of the cabin shutting the door behind us. He asked me

to sit down, but I first proceeded to rip the dispatches out of my

clothing, and with intense interest watched his features while he sat on

a camp stool by the window, his legs crossed, and read Sherman's letter.

I could see the glow of silent satisfaction as he glanced along the

lines that told of his great lieutenant's successes in the South. He

glanced at another letter I held in my hand. "It is for the President,"

I said. "He will be here yet to-night," he answered. "His boat must now

be coming up the bay."

Then General Grant questioned me as to all I knew about Sherman's army,

the character of the opposition he had met, the condition of his

soldiers, their clothing, the roads, the weather. He also asked me how I

had reached him with the dispatches, coming all the way from the

interior of North Carolina. He seemed to have thought for a moment that

I had come across Virginia on foot. He wanted to know of me again about

the terrible treatment of prisoners in the South. What I told him only

"confirmed," he said, what he had heard from a hundred sources.

Very shortly he heard the voice of General Ord in the outer room.

"Come in here, Ord," he said, holding the door open. "Come in and hear

the news from Sherman. Look at that, listen to this," and again he went

through Sherman's letter, reading parts of it aloud. "Good! Good!" cried

Ord, fairly dancing about the cabin, his spurs and saber jingling. "I

was really getting afraid." "Not I, not I, not a bit," exclaimed Grant

enthusiastically, as he rose to his feet. "_I knew my man. I knew

General Sherman._"

I was astonished now at the simple and perfectly frank manner with which

General Grant talked to me about the situation of the army. I had

ventured to ask if there was any outlook for the immediate fall of

Richmond or a battle.

"Very great," he answered. "I am only afraid Lee may slip out before we

can get a great blow at him. Any hour this may happen." Just then there

was cannonading. I wondered if a fight were commencing somewhere in the

line already. General Grant did not change a muscle in his face. "Send

out and see what the firing is," he said to an officer quietly, and then

as quietly continued talking, asking me to tell him all I knew of a

recent escapade of Kilpatrick and his cavalry. It happened that I knew

all about it. Only a couple of weeks before Kilpatrick and his

headquarters had been surprised in bed at a bivouac on the flank of

Sherman's army, and were surrounded and some were captured. By a heroic

struggle the cavalry leader had escaped his captors, had instantly

rallied his troops there in the dark woods and given the bold Rebels a

little drubbing. The next day I had been with Sherman at headquarters

and listened to Kilpatrick's recital of his adventure. My own narration

of the night's cavalry fight, reciting how the cavalrymen and his aids

dashed about with nothing on but their shirts, made General Grant smile

very audibly. "I had expected the whole thing to be about as you say,"

he exclaimed, in a grateful way, "but the Richmond newspapers which fell

into my hands made a big thing of the so-called capture of Sherman's

cavalry leader."

Once, as the General rose and stood directly in front of us, I was

astonished to see how small he seemed. I had seen Grant before, but on

horseback or in battle, and, somehow, I had always regarded him as a

rather large, solidly built man. To-day in the little back room of his

cabin, talking with him, I saw how mistaken I had been. General Grant,

as I now saw him, was, in fact, a little man. Several times he rose and

walked about the room. He was not more than five feet seven or eight

inches high, and he could not have weighed more than one hundred and

forty or fifty pounds. He wore a simple fatigue uniform, and his coat

thrown open gave him the appearance of being larger chested than he

really was. His brown hair was neither short nor long, and he wore a

full beard, well trimmed. Had I not known to whom I was talking, or had

I not seen the three stars on his shoulders, I would have supposed

myself in the presence of some simple army captain. There was nothing

whatever about him to announce the presence of genius or extraordinary

ability of any kind. He was in no sense a striking-looking man. His

manner and words to me were kind and earnest. There was an agreeable

look about his mouth and eyes that made him seem very sincere. Indeed,

if any one thing about him impressed me more than another, it was his

apparent sincerity and earnestness. And he looked to me like a man of

great common sense. Of vanity, pretence, or power there was not a single

sign. He could not have looked very greatly different when he was hewing

logs for his house at his father-in-law's farm ten years before, from

what he looked just now, quietly directing a million soldiers in the

greatest war of modern times.

Like General Sherman, he repeatedly expressed his interest concerning

the terrible experiences I had undergone in Southern prisons.

"I suppose you will want to get home as quickly as possible, won't you?"

he inquired, "or would you rather remain here awhile and look about the

army?" A steamer was to leave for the North in an hour. Privately, I was

fearing a sudden break-down of my health, and longed for a home that I

had visited but eight days during four long years of war. Then I thought

of my letter to Mr. Lincoln. The General seemed to anticipate my

thought. "Leave the President's letter with me," he said, "if you

choose, and I will give it to him, or stay over and give it to him

yourself."

There was no man living I was so anxious to see as Abraham Lincoln. And

this was my opportunity. But something like a premonition said, "Go

home." When I expressed my feeling General Grant stepped to the door of

the office room and directed General Rawlins to see that I be provided

with leave of absence and transportation. That little order, signed by

Rawlins, I still possess.

With an earnest handshake and good-by General Grant thanked me for

bringing him the dispatches. I was not to see him again for many

years.[C]

[C] At the town of Lucerne in Switzerland there is in front of the

Schweizerhof a quay lined with castanien trees. It overlooks the

beautiful lake. Long years after the war General Grant sat there on a

bench one quiet summer night and talked to me of the time I brought

the news to him from Sherman in the Carolinas. In a few weeks from

that night by the lakeside I had the honor of entertaining my old

commander at my own home, in the city of Zurich, where I was now

representing the government as one of his appointees. The order

naming me to go to Zurich had, on a certain time, been written by his

own hand.

This night at Zurich proved to be almost the last time I was ever to

see the great commander. His presence and words that evening are

among the treasured memories of my life.
