But the vital difficulty was, and will be again, to obtain an adequate number of good soldiers. We tried almost every system known to modern nations, all with more or less success--voluntary enlistments, the draft, and bought substitutes--and I think that all officers of experience will confirm my assertion that the men who voluntarily enlisted at the outbreak of the war were the best, better than the conscript, and far better than the bought substitute. When a regiment is once organized in a State, and mustered into the service of the United States, the officers and men become subject to the same laws of discipline and government as the regular troops. They are in no sense "militia," but compose a part of the Army of the United States, only retain their State title for convenience, and yet may be principally recruited from the neighborhood of their original organization: Once organized, the regiment should be kept full by recruits, and when it becomes difficult to obtain more recruits the pay should be raised by Congress, instead of tempting new men by exaggerated bounties. I believe it would have been more economical to have raised the pay of the soldier to thirty or even fifty dollars a month than to have held out the promise of three hundred and even six hundred dollars in the form of bounty. Toward the close of the war, I have often heard the soldiers complain that the "stay at-home" men got better pay, bounties, and food, than they who were exposed to all the dangers and vicissitudes of the battles and marches at the front. The feeling of the soldier should be that, in every event, the sympathy and preference of his government is for him who fights, rather than for him who is on provost or guard duty to the rear, and, like most men, he measures this by the amount of pay. Of course, the soldier must be trained to obedience, and should be "content with his wages;" but whoever has commanded an army in the field knows the difference between a willing, contented mass of men, and one that feels a cause of grievance. There is a soul to an army as well as to the individual man, and no general can accomplish the full work of his army unless he commands the soul of his men, as well as their bodies and legs.

The greatest mistake made in our civil war was in the mode of recruitment and promotion. When a regiment became reduced by the necessary wear and tear of service, instead of being filled up at the bottom, and the vacancies among the officers filled from the best noncommissioned officers and men, the habit was to raise new regiments, with new colonels, captains, and men, leaving the old and experienced battalions to dwindle away into mere skeleton organizations. I believe with the volunteers this matter was left to the States exclusively, and I remember that Wisconsin kept her regiments filled with recruits, whereas other States generally filled their quotas by new regiments, and the result was that we estimated a Wisconsin regiment equal to an ordinary brigade. I believe that five hundred new men added to an old and experienced regiment were more valuable than a thousand men in the form of a new regiment, for the former by association with good, experienced captains, lieutenants, and non-commissioned officers, soon became veterans, whereas the latter were generally unavailable for a year. The German method of recruitment is simply perfect, and there is no good reason why we should not follow it substantially.

On a road, marching by the flank, it would be considered "good order" to have five thousand men to a mile, so that a full corps of thirty thousand men would extend six miles, but with the average trains and batteries of artillery the probabilities are that it would draw out to ten miles. On a long and regular march the divisions and brigades should alternate in the lead, the leading division should be on the road by the earliest dawn, and march at the rate of about two miles, or, at most, two and a half miles an hour, so as to reach camp by noon. Even then the rear divisions and trains will hardly reach camp much before night. Theoretically, a marching column should preserve such order that by simply halting and facing to the right or left, it would be in line of battle; but this is rarely the case, and generally deployments are made "forward," by conducting each brigade by the flank obliquely to the right or left to its approximate position in line of battle, and there deployed. In such a line of battle, a brigade of three thousand infantry would occupy a mile of "front;" but for a strong line of battle five-thousand men with two batteries should be allowed to each mile, or a division would habitually constitute a double line with skirmishers and a reserve on a mile of "front."

The "feeding" of an army is a matter of the most vital importance, and demands the earliest attention of the general intrusted with a campaign. To be strong, healthy, and capable of the largest measure of physical effort, the soldier needs about three pounds gross of food per day, and the horse or mule about twenty pounds. When a general first estimates the quantity of food and forage needed for an army of fifty or one hundred thousand men, he is apt to be dismayed, and here a good staff is indispensable, though the general cannot throw off on them the responsibility. He must give the subject his personal attention, for the army reposes in him alone, and should never doubt the fact that their existence overrides in importance all other considerations. Once satisfied of this, and that all has been done that can be, the soldiers are always willing to bear the largest measure of privation. Probably no army ever had a more varied experience in this regard than the one I commanded in 1864'65.

Our base of supply was at Nashville, supplied by railways and the Cumberland River, thence by rail to Chattanooga, a "secondary base," and thence forward a single-track railroad. The stores came forward daily, but I endeavored to have on hand a full supply for twenty days in advance. These stores were habitually in the wagon-trains, distributed to corps, divisions, and regiments, in charge of experienced quartermasters and commissaries, and became subject to the orders of the generals commanding these bodies. They were generally issued on provision returns, but these had to be closely scrutinized, for too often the colonels would make requisitions for provisions for more men than they reported for battle. Of course, there are always a good many non-combatants with an army, but, after careful study, I limited their amount to twenty-five per cent. of the "effective strength," and that was found to be liberal. An ordinary army-wagon drawn by six mules may be counted on to carry three thousand pounds net, equal to the food of a full regiment for one day, but, by driving along beef-cattle, a commissary may safely count the contents of one wagon as sufficient for two days' food for a regiment of a thousand men; and as a corps should have food on hand for twenty days ready for detachment, it should have three hundred such wagons, as a provision-train; and for forage, ammunition, clothing, and other necessary stores, it was found necessary to have three hundred more wagons, or six hundred wagons in all, for a corps d'armee.

These should be absolutely under the immediate control of the corps commander, who will, however, find it economical to distribute them in due proportion to his divisions, brigades, and even regiments. Each regiment ought usually to have at least one wagon for convenience to distribute stores, and each company two pack-mules, so that the regiment may always be certain of a meal on reaching camp without waiting for the larger trains.

On long marches the artillery and wagon-trains should always have the right of way, and the troops should improvise roads to one side, unless forced to use a bridge in common, and all trains should have escorts to protect them, and to assist them in bad places. To this end there is nothing like actual experience, only, unless the officers in command give the subject their personal attention, they will find their wagon-trains loaded down with tents, personal baggage, and even the arms and knapsacks of the escort. Each soldier should, if not actually "sick or wounded," carry his musket and equipments containing from forty to sixty rounds of ammunition, his shelter-tent, a blanket or overcoat, and an extra pair of pants, socks, and drawers, in the form of a scarf, worn from the left shoulder to the right side in lieu of knapsack, and in his haversack he should carry some bread, cooked meat, salt, and coffee. I do not believe a soldier should be loaded down too much, but, including his clothing, arms, and equipment, he can carry about fifty pounds without impairing his health or activity. A simple calculation will show that by such a distribution a corps will-thus carry the equivalent of five hundred wagon-loads--an immense relief to the trains.

Where an army is near one of our many large navigable rivers, or has the safe use of a railway, it can usually be supplied with the full army ration, which is by far the best furnished to any army in America or Europe; but when it is compelled to operate away from such a base, and is dependent on its own train of wagons, the commanding officer must exercise a wise discretion in the selection of his stores. In my opinion, there is no better food for man than beef-cattle driven on the hoof, issued liberally, with salt, bacon, and bread. Coffee has also become almost indispensable, though many substitutes were found for it, such as Indian-corn, roasted, ground, and boiled as coffee; the sweet-potato, and the seed of the okra plant prepared in the same way. All these were used by the people of the South, who for years could procure no coffee, but I noticed that the women always begged of us some real coffee, which seems to satisfy a natural yearning or craving more powerful than can be accounted for on the theory of habit. Therefore I would always advise that the coffee and sugar ration be carried along, even at the expense of bread, for which there are many substitutes. Of these, Indian-corn is the best and most abundant. Parched in a frying-pan, it is excellent food, or if ground, or pounded and boiled with meat of any sort, it makes a most nutritious meal. The potato, both Irish and sweet, forms an excellent substitute for bread, and at Savannah we found that rice (was) also suitable, both for men and animals. For the former it should be cleaned of its husk in a hominy block, easily prepared out of a log, and sifted with a coarse corn bag; but for horses it should be fed in the straw. During the Atlanta campaign we were supplied by our regular commissaries with all sorts of patent compounds, such as desiccated vegetables, and concentrated milk, meat-biscuit, and sausages, but somehow the men preferred the simpler and more familiar forms of food, and usually styled these "desecrated vegetables and consecrated milk." We were also supplied liberally with lime-juice, sauerkraut, and pickles, as an antidote to scurvy, and I now recall the extreme anxiety of my medical director, Dr. Kittoe, about the scurvy, which he reported at one time as spreading and imperiling the army. This occurred at a crisis about Kenesaw, when the railroad was taxed to its utmost capacity to provide the necessary ammunition, food, and forage, and could not possibly bring us an adequate supply of potatoes and cabbage, the usual anti-scorbutics, when providentially the black berries ripened and proved an admirable antidote, and I have known the skirmish-line, without orders, to fight a respectable battle for the possession of some old fields that were full of blackberries. Soon, thereafter, the green corn or roasting-ear came into season, and I heard no more of the scurvy. Our country abounds with plants which can be utilized for a prevention to the scurvy; besides the above are the persimmon, the sassafras root and bud, the wild-mustard, the "agave," turnip tops, the dandelion cooked as greens, and a decoction of the ordinary pine-leaf.

For the more delicate and costly articles of food for the sick we relied mostly on the agents of the Sanitary Commission. I do not wish to doubt the value of these organizations, which gained so much applause during our civil war, for no one can question the motives of these charitable and generous people; but to be honest I must record an opinion that the Sanitary Commission should limit its operations to the hospitals at the rear, and should never appear at the front. They were generally local in feeling, aimed to furnish their personal friends and neighbors with a better class of food than the Government supplied, and the consequence was, that one regiment of a brigade would receive potatoes and fruit which would be denied another regiment close by: Jealousy would be the inevitable result, and in an army all parts should be equal; there should be no "partiality, favor, or affection." The Government should supply all essential wants, and in the hospitals to the rear will be found abundant opportunities for the exercise of all possible charity and generosity. During the war I several times gained the ill-will of the agents of the Sanitary Commission because I forbade their coming to the front unless they would consent to distribute their stores equally among all, regardless of the parties who had contributed them.

The sick, wounded, and dead of an army are the subjects of the greatest possible anxiety, and add an immense amount of labor to the well men. Each regiment in an active campaign should have a surgeon and two assistants always close at hand, and each brigade and division should have an experienced surgeon as a medical director. The great majority of wounds and of sickness should be treated by the regimental surgeon, on the ground, under the eye of the colonel. As few should be sent to the brigade or division hospital as possible, for the men always receive better care with their own regiment than with strangers, and as a rule the cure is more certain; but when men receive disabling wounds, or have sickness likely to become permanent, the sooner they go far to the rear the better for all. The tent or the shelter of a tree is a better hospital than a house, whose walls absorb fetid and poisonous emanations, and then give them back to the atmosphere. To men accustomed to the open air, who live on the plainest food, wounds seem to give less pain, and are attended with less danger to life than to ordinary soldiers in barracks.
