Dick spent a week or more in Nashville and he saw the arrival of one of General Grant's divisions on the fleet under Commodore Foote. Once more he appreciated the immense value of the rivers and the fleet to the North.  
He and the two lads who were now knitted to him by sympathy, and hardships and dangers shared, enjoyed their stay in Nashville. It was pleasant to sleep once more in houses and to be sheltered from rain and frost and snow. It was pleasant, too, for these youths, who were devoted to the union, to think that their armies had made such progress in the west. The silent and inflexible Grant had struck the first great blow for the North. The immense Confederate line in the west was driven far southward, and the capital of one of the most vigorous of the secessionist states was now held by the union.
 
But a little later, news not so pleasant came to them. The energy and success of Grant had aroused jealousy. Halleck, his superior, the general of books and maps at St. Louis, said that he had transcended the limits of his command. He was infringing upon territory of other Northern generals. Halleck had not found him to be the yielding subordinate who would win successes and let others have the credit.
 
Grant was practically relieved of his command, and when Dick heard it he felt a throb of rage. Boy as he was, he knew that what had been won must be held. Johnston had stopped at Murfreesborough, thirty or forty miles away. His troops had recovered from their panic, caused by the fall of Donelson. Fresh regiments and brigades were joining him. His army was rising to forty thousand men, and officers like Colonel Winchester began to feel apprehensive.
 
Now came a period of waiting. The Northern leaders, as happened so often in this war, were uncertain of their authority, and were at cross-purposes. They seldom had the power of initiative that was permitted to the Southern generals, and of which they made such good use. Dick saw that the impression made by Donelson was fading. The North was reaping no harvest, and the South was lifting up its head again.
 
While he was in Nashville he received a letter from his mother in reply to one of his that he had written to her just after Donelson. She was very thankful that her son had gone safely through the battle, and since he must fight in war, which was terrible in any aspect, she was glad that he had borne himself bravely. She was glad that Colonel Kenton had escaped capture. Her brother-in-law was always good to her and was a good man. She had also received a letter from his son, her nephew, written from Richmond, She loved Harry Kenton, too, and sympathized with him, but she could not see how both sides could prevail.
 
Dick read the letter over and over again and there was a warm glow about his heart. What a brave woman his mother was! She said nothing about his coming back home, or leaving the war. He wrote a long reply, and he told her only of the lighter and more cheerful events that they had encountered. He described Warner, Pennington, and the sergeant, and said that he had the best comrades in the world. He told, too, of his gallant and high-minded commander, Colonel Arthur Winchester.
 
He was sure that the letter would reach her promptly, as it passed all the way through territory now controlled by the North. The next day after sending it he heard with joy that Grant was restored to his command, and two days later Colonel Winchester and his men were ordered to join him at Pittsburg Landing, on the Tennessee River. They heard also that Buell, with his whole division, was soon to march to the same place, and they saw in it an omen of speedy and concentrated action.
 
“I imagine,” said Warner, “that we'll soon go down in Mississippi hunting Johnston. We must outnumber the Johnny Rebs at least two to one. I'm not a general, though any one can see that I ought to be, and if we were to follow Johnston's army and crush it the war would soon be ended in the west.”
 
“You've got a mighty big 'if',” said Dick. “If we march into Mississippi we get pretty far from our base. We'll have to send a long distance through hostile country for fresh supplies and fresh troops, while the Southerners will be nearer to their own. Besides, it's not so certain that we can destroy Johnston when we find him.”
 
“Your talk sounds logical, and that being the case, I'll leave our future movements to General Grant. Anyway, it's a good thing not to have so much responsibility on your shoulders.”
 
They came in a few days to the great camp on the Tennessee. Spring was now breaking through the crust of winter. Touches of green were appearing on the forests and in the fields. Now and then the wonderful pungent odor of the wilderness came to them and life seemed to have taken on new zest. They were but boys in years, and the terrible scenes of Donelson could not linger with them long.
 
They found Colonel Newcomb and the little detachment of Pennsylvanians with Grant, and Colonel Winchester, resuming command of his regiment, camped by their side, delighted to be with old friends again. Colonel Winchester had lost a portion of his regiment, but there were excuses. It had happened in a country well known to the enemy and but little known to him, and he had been attacked in overwhelming force by the rough-riding Forrest, who was long to be a terror to the union divisions. But he had achieved the task on which he had been sent, and he was thanked by his commander.
 
Dick, as he went on many errands or walked about in the course of his leisure hours with his friends, watched with interest the growth of a great army. There were more men here upon the banks of the Tennessee than he had seen at Bull Run. They were gathered full forty thousand strong, and General Buell's army also, he learned, had been put under command of General Grant and was advancing from Nashville to join him.
 
Dick also observed with extreme interest the ground upon which they were encamped and the country surrounding it. There was the deep Tennessee, still swollen by spring rains, upon the left bank of which they lay, with the stream protecting one flank. In the river were some of the gunboats which had been of such value to Grant. All about them was rough, hilly country, almost wholly covered with brushwood and tall forest. There were three deep creeks, given significant names by the pioneers. Lick Creek flowed to the south of them into the Tennessee, and Owl Creek to the north sought the same destination. A third, Snake Creek, was lined with deep and impassable swamps to its very junction with the river.
 
Some roads of the usual frontier type ran through this region, and at a point within the Northern lines stood a little primitive log church that they called Shiloh. It was of the kind that the pioneers built everywhere as they moved from the Atlantic to the Pacific. Shiloh belonged to a little body of Methodists. Dick went into it more than once. There was no pastor and no congregation now, but the little church was not molested. He sat more than once on an uncompromising wooden bench, and looked out through a window, from which the shutter was gone, at the forest and the army.
 
Sitting here in this primitive house of worship, he would feel a certain sadness. It seemed strange that a great army, whose purpose was to destroy other armies, should be encamped around a building erected in the cause of the Prince of Peace. The mighty and terrible nature of the war was borne in upon him more fully than ever.
 
But optimism was supreme among the soldiers. They had achieved the great victory of Donelson in the face of odds that had seemed impossible. They could defeat all the Southern forces that lay between them and the Gulf. The generals shared their confidence. They did not fortify their camp. They had not come that far South to fight defensive battles. It was their place to attack and that of the men in gray to defend. They had advanced in triumph almost to the Mississippi line, and they would soon be pursuing their disorganized foe into that Gulf State.
 
Several new generals came to serve under Grant. Among them was one named Sherman, to whom Dick bore messages several times, and who impressed him with his dry manner and curt remarks which were yet so full of sense.
 
It was Sherman's division, in fact, that was encamped around the little church, and Dick soon learned his opinions. He did not believe that they would so easily conquer the South. He did not look for any triumphal parade to the Gulf. In the beginning of the war he had brought great enmity and criticism upon himself by saying that 200,000 men at least would be needed at once to crush the Confederacy in the west alone. And yet it was to take more than ten times that number four bitter years to achieve the task in both west and east.
 
But optimism continued to reign in the union army. Buell would arrive soon with his division and then seventy thousand strong they would resume their march southward, crushing everything. Meanwhile it was pleasant while they waited. They had an abundance of food. They were well sheltered from the rains. The cold days were passing, nature was bursting into its spring bloom, and the crisp fresh winds that blew from the west and south were full of life and strength. It was a joy merely to breathe.
 
One rainy day the three boys, who had met by chance, went into the little church for shelter from a sudden spring rain. From the shutterless window Dick saw Sergeant Whitley scurrying in search of a refuge, and they called to him. He came gladly and took a seat in one of the rough wooden pews of the little church of Shiloh. The three boys had the greatest respect for the character and judgment of the sergeant, and Dick asked him when he thought the army would march.
 
“They don't tell these things to sergeants,” said Whitley.
 
“But you see and you know a lot about war.”
 
“Well, you've noticed that the army ain't gettin' ready to march. When General Buell gets here we'll have nigh onto seventy thousand men, and seventy thousand men can't lift themselves up by their bootstraps an' leave, all in a mornin'.”
 
“But we don't have to hurry,” said Pennington. “There's no Southern army west of the Alleghanies that could stand before our seventy thousand men for an hour.”
 
“General Buell ain't here yet.”
 
“But he's coming.”
 
“But he ain't here yet,” persisted the sergeant, “an' he can't be here for several days, 'cause the roads are mighty deep in the spring mud. Don't say any man is here until he is here. An' I tell you that General Johnston, with whom we've got to deal, is a great man. I wasn't with him when he made that great march through the blizzards an' across the plains to Salt Lake City to make the Mormons behave, but I've served with them that was. An' I've never yet found one of them who didn't say General Johnston was a mighty big man. Soldiers know when the right kind of a man is holdin' the reins an' drivin' 'em. Didn't we all feel that we was bein' driv right when General Grant took hold?”
 
“We all felt it,” said the three in chorus.
 
“Of course you did,” said the sergeant, “an' now I've got a kind of uneasy feelin' over General Johnston. Why don't we hear somethin' from him? Why don't we know what he's doin'? We haven't sent out any scoutin' parties. On the plains, no matter how strong we was, we was always on the lookout for hostile Indians, while here we know there is a big Confederate army somewhere within fifty miles of us, but don't take the trouble to look it up.”
 
“That's so,” said Warner. “Caution represents less than five per cent of our effectiveness. But I suppose we can whip the Johnnies anyway.”
 
“Of course we can,” said Pennington, who was always of a most buoyant temperament.
 
Sergeant Whitley went to the shutterless window, and looked out at the forest and the long array of tents.
 
“The rain is about over,” he said. “It was just a passin' shower. But it looks as if it had already added a fresh shade of green to the leaves and grass. Cur'us how quick a rain can do it in spring, when everything is just waitin' a chance to grow, and bust into bloom. I've rid on the plains when everything was brown an' looked dead. 'Long come a big rain an' the next day everything was green as far as the eye could reach an' you'd see little flowers bloomin' down under the shelter of the grass.”
 
“I didn't know you had a poetical streak in you, sergeant,” said Dick, who marked his abrupt change from the discussion of the war to a far different topic.
 
“I think some of it is in every man,” replied Sergeant Whitley gravely. “I remember once that when we had finished a long chase after some Northern Cheyennes through mighty rough and dry country we came to a little valley, a kind of a pocket in the hills, fed by a fine creek, runnin' out of the mountains on one side, into the mountains on the other. The pocket was mebbe two miles long an' mebbe a mile across, an' it was chock full of green trees an' green grass, an' wild flowers. We enjoyed its comforts, but do you think that was all? Every man among us, an' there was at least a dozen who couldn't read, admired its beauties, an' begun to talk softer an' more gentle than they did when they was out on the dry plains. An' you feel them things more in war than you do at any other time.”
 
“I suppose you do,” said Dick. “The spring is coming out now in Kentucky where I live, and I'd like to see the new grass rippling before the wind, and the young leaves on the trees rustling softly together.”
 
“Stop sentimentalizing,” said Warner. “If you don't it won't be a minute before Pennington will begin to talk about his Nebraska plains, and how he'd like to see the buffalo herds ten million strong, rocking the earth as they go galloping by.”
 
Pennington smiled.
 
“I won't see the buffalo herds,” he said, “but look at the wild fowl going north.”
 
They left the window as the rain had ceased, and went outside. All this region was still primitive and thinly settled, and now they saw flocks of wild ducks and wild geese winging northward. The next day the heavens themselves were darkened by an immense flight of wild pigeons. The country cut up by so many rivers, creeks and brooks swarmed with wild fowl, and more than once the soldiers roused up deer from the thickets.
 
The second day after the talk of the four in the little church Dick, who was now regarded as a most efficient and trusty young staff officer, was sent with a dispatch to General Buell requesting him to press forward with as much speed as he could to the junction with General Grant. Several other aides were sent by different routes, in order to make sure that at least one would arrive, but Dick, through his former ride with Colonel Winchester to Nashville, had the most knowledge of the country, and hence was likely to reach Buell first.
 
As the boy rode from the camp and crossed the river into the forest he looked back, and he could not fail to notice to what an extent it was yet a citizen army, and not one of trained soldiers. The veteran sergeant had already called his attention to what he deemed grave omissions. In the three weeks that they had been lying there they had thrown up no earthworks. Not a spade had touched the earth. Nor was there any other defense of any kind. The high forest circled close about them, dense now with foliage and underbrush, hiding even at a distance of a few hundred yards anything that might lie within. The cavalry in these three weeks had made one scouting expedition, but it was slight and superficial, resulting in nothing. The generals of divisions posted their own pickets separately, leaving numerous wide breaks in the line, and the farmer lads, at the change of guard, invariably fired their rifles in the air, to signify the joy of living, and because it was good to hear the sound.
 
Now that he was riding away from them, these things impressed Dick more than when he was among them. Sergeant Whitley's warning and pessimistic words came back to him with new force, but, as he rode into the depths of the forest, he shook off all depression. Those words, “Seventy thousand strong!” continually recurred to him. Yes, they would be seventy thousand strong when Buell came up, and the boys were right. Certainly there was no Confederate force in the west that could resist seventy thousand troops, splendidly armed, flushed with victory and led by a man like Grant.
 
Seventy thousand strong! Dick's heart beat high at the unuttered words. Why should Grant fortify? It was for the enemy, not for him, to do such a thing. Nor was it possible that Johnston even behind defenses could resist the impact of the seventy thousand who had been passing from one victory to another, and who were now in the very heart of the enemy's country.
 
His heart continued to beat high and fast as he rode through the green forest. Its strong, sweet odors gave a fillip to his blood, and he pressed his horse to new speed. He rode without interruption night and day, save a few hours now and then for sleep, and reached the army of Buell which deep in mud was toiling slowly forward.
 
Buell was not as near to Shiloh as Dick had supposed, but his march had suffered great hindrances. Halleck, in an office far away in St. Louis, had undertaken to manage the campaign. His orders to Buell and his command to Grant had been delayed. Buell, ............
