Nevertheless, the regimental organization for artillery has always been maintained in this country for cla.s.sification and promotion.
Twelve companies compose a regiment, and, though probably no colonel ever commanded his full regiment in the form of twelve batteries, yet in peace they occupy our heavy sea-coast forts or act as infantry; then the regimental organization is both necessary and convenient.
But the infantry composes the great ma.s.s of all armies, and the true form of the regiment or unit has been the subject of infinite discussion; and, as I have stated, during the civil war the regiment was a single battalion of ten companies. In olden times the regiment was composed of eight battalion companies and two flank companies. The first and tenth companies were armed with rifles, and were styled and used as "skirmishers;" but during "the war they were never used exclusively for that special purpose, and in fact no distinction existed between them and the other eight companies.
The ten-company organization is awkward in practice, and I am satisfied that the infantry regiment should have the same identical organization as exists for the cavalry and artillery, viz., twelve companies, so as to be susceptible of division into three battalions of four companies each.
These companies should habitually be about a hundred one men strong, giving twelve hundred to a regiment, which in practice would settle down to about one thousand men.
Three such regiments would compose a brigade, three brigades a division, and three divisions a corps. Then, by allowing to an infantry corps a brigade of cavalry and six batteries of field-artillery, we would have an efficient corps d"armee of thirty thousand men, whose organization would be simple and most efficient, and whose strength should never be allowed to fall below twenty-five thousand men.
The corps is the true unit for grand campaigns and battle, should have a full and perfect staff, and every thing requisite for separate action, ready at all times to be detached and sent off for any nature of service. The general in command should have the rank of lieutenant-general, and should be, by experience and education, equal to any thing in war. Habitually with us he was a major- general, specially selected and a.s.signed to the command by an order of the President, const.i.tuting, in fact, a separate grade.
The division is the unit of administration, and is the legitimate command of a major general.
The brigade is the next subdivision, and is commanded by a brigadier-general.
The regiment is the family. The colonel, as the father, should have a personal acquaintance with every officer and man, and should instill a feeling of pride and affection for himself, so that his officers and men would naturally look to him for personal advice and instruction. In war the regiment should never be subdivided, but should always be maintained entire. In peace this is impossible.
The company is the true unit of discipline, and the captain is the company. A good captain makes a good company, and he should have the power to reward as well as punish. The fact that soldiers world naturally like to have a good fellow for their captain is the best reason why he should be appointed by the colonel, or by some superior authority, instead of being elected by the men.
In the United States the people are the "sovereign," all power originally proceeds from them, and therefore the election of officers by the men is the common rule. This is wrong, because an army is not a popular organization, but an animated machine, an instrument in the hands of the Executive for enforcing the law, and maintaining the honor and dignity of the nation; and the President, as the const.i.tutional commander-in-chief of the army and navy, should exercise the power of appointment (subject to the confirmation of the Senate) of the officers of "volunteers," as well as of "regulars."
No army can be efficient unless it be a unit for action; and the power must come from above, not from below: the President usually delegates his power to the commander-in-chief, and he to the next, and so on down to the lowest actual commander of troops, however small the detachment. No matter how troops come together, when once united, the highest officer in rank is held responsible, and should be consequently armed with the fullest power of the Executive, subject only to law and existing orders. The more simple the principle, the greater the likelihood of determined action; and the less a commanding officer is circ.u.mscribed by bounds or by precedent, the greater is the probability that he will make the best use of his command and achieve the best results.
The Regular Army and the Military Academy at West Point have in the past provided, and doubtless will in the future provide an ample supply of good officers for future wars; but, should their numbers be insufficient, we can always safely rely on the great number of young men of education and force of character throughout the country, to supplement them. At the close of our civil war, lasting four years, some of our best corps and division generals, as well as staff-officers, were from civil life; but I cannot recall any of the most successful who did not express a regret that he had not received in early life instruction in the elementary principles of the art of war, instead of being forced to acquire this knowledge in the dangerous and expensive school of actual war.
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 subst.i.tutes--and I think that all officers of experience will confirm my a.s.sertion 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 subst.i.tute. 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 t.i.tle for convenience, and yet may be princ.i.p.ally 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 ma.s.s 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 a.s.sociation 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 const.i.tute 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 quant.i.ty 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 c.u.mberland 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 a.s.sist 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 subst.i.tutes 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 subst.i.tutes.
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 subst.i.tute 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 coa.r.s.e 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-s...o...b..tics, 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 sa.s.safras 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 cla.s.s 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 a.s.sistants 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.
Wounds which, in 1861, would have sent a man to the hospital for months, in 1865 were regarded as mere scratches, rather the subject of a joke than of sorrow. To new soldiers the sight of blood and death always has a sickening effect, but soon men become accustomed to it, and I have heard them exclaim on seeing a dead comrade borne to the rear, "Well, Bill has turned up his toes to the daisies."
Of course, during a skirmish or battle, armed men should never leave their ranks to attend a dead or wounded comrade--this should be seen to in advance by the colonel, who should designate his musicians or company cooks as hospital attendants, with a white rag on their arm to indicate their office. A wounded man should go himself (if able) to the surgeon near at hand, or, if he need help, he should receive it from one of the attendants and not a comrade.
It is wonderful how soon the men accustom themselves to these simple rules. In great battles these matters call for a more enlarged attention, and then it becomes the duty of the division general to see that proper stretchers and field hospitals are ready for the wounded, and trenches are dug for the dead. There should be no real neglect of the dead, because it has a bad effect on the living; for each soldier values himself and comrade as highly as though he were living in a good house at home.
The regimental chaplain, if any, usually attends the burials from the hospital, should make notes and communicate details to the captain of the company, and to the family at home. Of course it is usually impossible to mark the grave with names, dates, etc., and consequently the names of the "unknown" in our national cemeteries equal about one-half of all the dead.
Very few of the battles in which I have partic.i.p.ated were fought as described in European text-books, viz., in great ma.s.ses, in perfect order, manoeuvring by corps, divisions, and brigades. We were generally in a wooded country, and, though our lines were deployed according to tactics, the men generally fought in strong skirmish-lines, taking advantage of the shape of ground, and of every cover. We were generally the a.s.sailants, and in wooded and broken countries the "defensive" had a positive advantage over us, for they were always ready, had cover, and always knew the ground to their immediate front; whereas we, their a.s.sailants, had to grope our way over unknown ground, and generally found a cleared field or prepared entanglements that held us for a time under a close and withering fire. Rarely did the opposing lines in compact order come into actual contact, but when, as at Peach-Tree Creek and Atlanta, the lines did become commingled, the men fought individually in every possible style, more frequently with the musket clubbed than with the bayonet, and in some instances the men clinched like wrestlers, and went to the ground together.
Europeans frequently criticised our war, because we did not always take full advantage of a victory; the true reason was, that habitually the woods served as a screen, and we often did not realize the fact that our enemy had retreated till he was already miles away and was again intrenched, having left a mere skirmish-line to cover the movement, in turn to fall back to the new position.
Our war was fought with the muzzle-loading rifle. Toward the close I had one brigade (Walcutt"s) armed with breech-loading "Spencer"s;"
the cavalry generally had breach-loading carbines, "Spencer"s" and "Sharp"s," both of which were good arms.
The only change that breech-loading arms will probably make in the art and practice of war will be to increase the amount of ammunition to be expended, and necessarily to be carried along; to still further "thin out" the lines of attack, and to reduce battles to short, quick, decisive conflicts. It does not in the least affect the grand strategy, or the necessity for perfect organization, drill, and discipline. The companies and battalions will be more dispersed, and the men will be less under the immediate eye of their officers, and therefore a higher order of intelligence and courage on the part of the individual soldier will be an element of strength.
When a regiment is deployed as skirmishers, and crosses an open field or woods, under heavy fire, if each man runs forward from tree to tree, or stump to stump, and yet preserves a good general alignment, it gives great confidence to the men themselves, for they always keep their eyes well to the right and left, and watch their comrades; but when some few hold back, stick too close or too long to a comfortable log, it often stops the line and defeats the whole object. Therefore, the more we improve the fire-arm the more will be the necessity for good organization, good discipline and intelligence on the part of the individual soldier and officer.
There is, of course, such a thing as individual courage, which has a value in war, but familiarity with danger, experience in war and its common attendants, and personal habit, are equally valuable traits, and these are the qualities with which we usually have to deal in war. All men naturally shrink from pain and danger, and only incur their risk from some higher motive, or from habit; so that I would define true courage to be a perfect sensibility of the measure of danger, and a mental willingness to incur it, rather than that insensibility to danger of which I have heard far more than I have seen. The most courageous men are generally unconscious of possessing the quality; therefore, when one professes it too openly, by words or bearing, there is reason to mistrust it. I would further ill.u.s.trate my meaning by describing a man of true courage to be one who possesses all his faculties and senses perfectly when serious danger is actually present.
Modern wars have not materially changed the relative values or proportions of the several arms of service: infantry, artillery, cavalry, and engineers. If any thing, the infantry has been increased in value. The danger of cavalry attempting to charge infantry armed with breech-loading rifles was fully ill.u.s.trated at Sedan, and with us very frequently. So improbable has such a thing become that we have omitted the infantry-square from our recent tactics. Still, cavalry against cavalry, and as auxiliary to infantry, will always be valuable, while all great wars will, as heretofore, depend chiefly on the infantry. Artillery is more valuable with new and inexperienced troops than with veterans. In the early stages of the war the field-guns often bore the proportion of six to a thousand men; but toward the close of the war one gun; or at most two, to a thousand men, was deemed enough.
Sieges; such as characterized the wars of the last century, are too slow for this period of the world, and the Prussians recently almost ignored them altogether, penetrated France between the forts, and left a superior force "in observation," to watch the garrison and accept its surrender when the greater events of the war ahead made further resistance useless; but earth-forts, and especially field-works, will hereafter play an important part in war, because they enable a minor force to hold a superior one in check for a time, and time is a most valuable element in all wars.
It was one of Prof. Mahan"s maxims that the spade was as useful in war as the musket, and to this I will add the axe. The habit of intrenching certainly does have the effect of making new troops timid. When a line of battle is once covered by a good parapet, made by the engineers or by the labor of the men themselves, it does require an effort to make them leave it in the face of danger; but when the enemy is intrenched, it becomes absolutely necessary to permit each brigade and division of the troops immediately opposed to throw up a corresponding trench for their own protection in case of a sudden sally. We invariably did this in all our recent campaigns, and it had no ill effect, though sometimes our troops were a little too slow in leaving their well-covered lines to a.s.sail the enemy in position or on retreat. Even our skirmishers were in the habit of rolling logs together, or of making a lunette of rails, with dirt in front, to cover their bodies; and, though it revealed their position, I cannot say that it worked a bad effect; so that, as a rule, it may safely be left to the men themselves: On the "defensive," there is no doubt of the propriety of fortifying; but in the a.s.sailing army the general must watch closely to see that his men do not neglect an opportunity to drop his precautionary defenses, and act promptly on the "offensive" at every chance.
I have many a time crept forward to the skirmish-line to avail myself of the cover of the pickets "little fort," to observe more closely some expected result; and always talked familiarly with the men, and was astonished to see how well they comprehended the general object, and how accurately they were informed of the sate of facts existing miles away from their particular corps. Soldiers are very quick to catch the general drift and purpose of a campaign, and are always sensible when they are well commanded or well cared for. Once impressed with this fact, and that they are making progress, they bear cheerfully any amount of labor and privation.
In camp, and especially in the presence of an active enemy, it is much easier to maintain discipline than in barracks in time of peace. Crime and breaches of discipline are much less frequent, and the necessity for courts-martial far less. The captain can usually inflict all the punishment necessary, and the colonel should always. The field-officers" court is the best form for war, viz., one of the field-officers-the lieutenant-colonel or major --can examine the case and report his verdict, and the colonel should execute it. Of course, there are statutory offenses which demand a general court-martial, and these must be ordered by the division or corps commander; but, the presence of one of our regular civilian judge-advocates in an army in the field would be a first-cla.s.s nuisance, for technical courts always work mischief.
Too many courts-martial in any command are evidence of poor discipline and inefficient officers.
For the rapid transmission of orders in an army covering a large s.p.a.ce of ground, the magnetic telegraph is by far the best, though habitually the paper and pencil, with good mounted orderlies, answer every purpose. I have little faith in the signal-service by flags and torches, though we always used them; because, almost invariably when they were most needed, the view was cut off by intervening trees, or by mists and fogs. There was one notable instance in my experience, when the signal-flags carried a message.
of vital importance over the heads of Hood"s army, which had interposed between me and Allatoona, and had broken the telegraph-wires--as recorded in Chapter XIX.; but the value of the magnetic telegraph in war cannot be exaggerated, as was ill.u.s.trated by the perfect concert of action between the armies in Virginia and Georgia during 1864. Hardly a day intervened when General Grant did not know the exact state of facts with me, more than fifteen hundred miles away as the wires ran. So on the field a thin insulated wire may be run on improvised stakes or from tree to tree for six or more miles in a couple of hours, and I have seen operators so skillful, that by cutting the wire they would receive a message with their tongues from a distant station. As a matter of course, the ordinary commercial wires along the railways form the usual telegraph-lines for an army, and these are easily repaired and extended as the army advances, but each army and wing should have a small party of skilled men to put up the field-wire, and take it down when done. This is far better than the signal-flags and torches. Our commercial telegraph-lines will always supply for war enough skillful operators.
The value of railways is also fully recognized in war quite as much as, if not more so than, in peace. The Atlanta campaign would simply have been impossible without the use of the railroads from Louisville to Nashville--one hundred and eighty-five miles--from Nashville to Chattanooga--one hundred and fifty-one miles--and from Chattanooga to Atlanta--one hundred and thirty-seven miles. Every mile of this "single track" was so delicate, that one man could in a minute have broken or moved a rail, but our trains usually carried along the tools and means to repair such a break. We had, however, to maintain strong guards and garrisons at each important bridge or trestle--the destruction of which would have necessitated time for rebuilding. For the protection of a bridge, one or two log block houses, two stories high, with a piece of ordnance and a small infantry guard, usually sufficed. The block-house had a small parapet and ditch about it, and the roof was made shot proof by earth piled on. These points could usually be reached only by a dash of the enemy"s cavalry, and many of these block houses successfully resisted serious attacks by both cavalry and artillery. The only block-house that was actually captured on the main was the one described near Allatoona. Our trains from Nashville forward were operated under military rules, and ran about ten miles an hour in gangs of four trains of ten cars each. Four such groups of trains daily made one hundred and sixty cars, of ten tons each, carrying sixteen hundred tons, which exceeded the absolute necessity of the army, and allowed for the accidents that were common and inevitable. But, as I have recorded, that single stem of railroad, four hundred and seventy-three miles long, supplied an army of one hundred thousand men and thirty-five thousand animals for the period of one hundred and ninety-six days, viz., from May 1 to November 12, 1864. To have delivered regularly that amount of food and forage by ordinary wagons would have required thirty-six thousand eight hundred wagons of six mules each, allowing each wagon to have hauled two tons twenty miles each day, a simple impossibility in roads such as then existed in that region of country. Therefore, I reiterate that the Atlanta campaign was an impossibility without these railroads; and only then, because we had the men and means to maintain and defend them, in addition to what were necessary to overcome the enemy.
Habitually, a pa.s.senger-car will carry fifty men with their necessary baggage. Box-cars, and even platform-cars, answer the purpose well enough, but they, should always have rough board-seats. For sick and wounded men, box-cars filled with straw or bushes were usually employed. Personally, I saw but little of the practical working of the railroads, for I only turned back once as far as Resaca; but I had daily reports from the engineer in charge, and officers who came from the rear often explained to me the whole thing, with a description of the wrecked trains all the way from Nashville to Atlanta. I am convinced that the risk to life to the engineers and men on that railroad fully equaled that on the skirmish-line, called for as high an order of courage, and fully equaled it in importance. Still, I doubt if there be any necessity in time of peace to organize a corps specially to work the military railroads in time of war, because in peace these same men gain all the necessary experience, possess all the daring and courage of soldiers, and only need the occasional protection and a.s.sistance of the necessary train-guard, which may be composed of the furloughed men coming and going, or of details made from the local garrisons to the rear.
For the transfer of large armies by rail, from one theatre of action to another by the rear--the cases of the transfer of the Eleventh and Twelfth Corps--General Hooker, twenty-three thousand men--from the East to Chattanooga, eleven hundred and ninety-two miles in seven days, in the fall of 1863; and that of the Army of the Ohio--General Schofield, fifteen thousand men--from the valley of the Tennessee to Washington, fourteen hundred miles in eleven days, en route to North Carolina in January, 1865, are the best examples of which I have any knowledge, and reference to these is made in the report of the Secretary of War, Mr. Stanton, dated November 22, 1865.
Engineer troops attached to an army are habitually employed in supervising the construction of forts or field works of a nature more permanent than the lines need by the troops in motion, and in repairing roads and making bridges. I had several regiments of this kind that were most useful, but as a rule we used the infantry, or employed parties of freedmen, who worked on the trenches at night while the soldiers slept, and these in turn rested by day. Habitually the repair of the railroad and its bridges was committed to hired laborers, like the English navies, under the supervision of Colonel W. W. Wright, a railroad-engineer, who was in the military service at the time, and his successful labors were frequently referred to in the official reports of the campaign.
For the pa.s.sage of rivers, each army corps had a pontoon-train with a detachment of engineers, and, on reaching a river, the leading infantry division was charged with the labor of putting it down.
Generally the single pontoon-train could provide for nine hundred feet of bridge, which sufficed; but when the rivers were very wide two such trains would be brought together, or the single train was supplemented by a trestle-bridge, or bridges made on crib-work, out of timber found near the place. The pontoons in general use were skeleton frames, made with a hinge, so as to fold back and const.i.tute a wagon-body. In this same wagon were carried the cotton canvas cover, the anchor and chains, and a due proportion of the balks, cheeses, and lashings. All the troops became very familiar with their mechanism and use, and we were rarely delayed by reason of a river, however broad. I saw, recently, in Aldershot, England, a very complete pontoon-train; the boats were sheathed with wood and felt, made very light; but I think these were more liable to chafing and damage in rough handling than were our less expensive and rougher boats. On the whole, I would prefer the skeleton frame and canvas cover to any style of pontoon that I have ever seen.
In relation to guards, pickets, and vedettes, I doubt if any discoveries or improvements were made during our war, or in any of the modern wars in Europe. These precautions vary with the nature of the country and the situation of each army. When advancing or retreating in line of battle, the usual skirmish-line const.i.tutes the picket-line, and may have "reserves," but usually the main line of battle const.i.tutes the reserve; and in this connection I will state that the recent innovation introduced into the new infantry tactics by General Upton is admirable, for by it each regiment, brigade, and division deployed, sends forward as "skirmishers" the one man of each set of fours, to cover its own front, and these can be recalled or reenforced at pleasure by the bugle-signal.
