Camps designed to cover and guard a country, are constructed when the army has not sufficient strength to advance, or when the season prevents, or some other cause interferes with the prosecution of hostilities, while at the same time it is necessary to occupy a portion of the hostile territory. We have had numerous examples of this kind of campsindeed, our armies occupy them generally while lying inactive during the winter. The character of the ground must always determine the shape and features of such a camp, but unless peculiar modifying circumstances dictate otherwise, the general form is that of the arc of a circle. This, with extensions at the sides to cover the flanks, and a rear guard, is the best for protection. The extent of this kind of camp is governed by circumstances, but is much greater, generally, than would be supposed. The camp of an army of 100,000 men, designed to cover any considerable district of territory, in a country where hills and rivers assist in giving protection, might have a front (including flanking parties of cavalry) of from 30 to 50 miles, and a depth of from 10 to 20; besides a continuous chain of forces in the rear, guarding communications with the base of supplies, from 10 to 50 miles distant.
Camps in line of battle are generally established when opposing armies, lying in proximity, must be on the alert for attacks. They cover but little more ground than is required for the manœuvres of the force, and are so arranged that, in case of probable conflict, the troops can assume immediately the formations of battle. Such camps are arranged in two or three lines, adapted to the natural features of the country for defence. The approach of the enemy having been communicated from the outposts, the tents are rapidly struck, the baggage loaded and sent to the rear, and in an hour the army is free from all encumbrances, and ready to meet the advancing foe. Usually, when armies lie in contact, expecting battle, the troops bivouacno tents being pitched except at the headquarters of superior commanders, and at other places sufficiently in the rear to be free from immediate danger. The troops may be obliged to remain thus for a day or two, no fires being permitted in the advanced lines, so that their positions may not be indicated.
The season for the suspension of active hostilities having arrived, it is necessary for the commander of an army to select some place in which his forces can remain for the winterwhere they will have sufficient facilities for fuel and water, where their health can be preserved, where they can be protected against surprises or annoyance, where the country can be covered and guarded, and where the supplies can be drawn with security from the base of operations. After a due consideration of all the intelligence that can be obtained upon these points, the commander issues his general directions, the various corps move to their designated positions, and preparations for the habitations of the winter are made. Each corps commander, either personally or by his staff officers, makes a survey of his ground, and assigns the positions of his divisions. If within a few miles of the enemy, he throws detachments of observation toward the front, and then proceeds to establish his picket line, usually some three or five miles in advance of his main line. Precautions for security being thus adopted, more minute inspections of the ground are made, so that unhealthy positions may be avoided. The troops, being placed, immediately proceed to clear the sites of their respective encampments, and wagons are set to work to bring in logs with which huts may be constructed. In about a week thousands of diminutive log houses arise, roofed with the shelter tents of the soldiers, or, when the occupants have sufficient handicraft ability, with rough shingles. Shelters are erected, as far as possible, for the animals, generally being nothing more than frameworks covered with pine brush. If there are lumber mills in the vicinity, they are set to work, and boards sawed for floors to the tents and hospitals. The adjacent forests now begin to disappear rapidly, leaving nothing but an unsightly array of stumps; for a regiment is entitled to about two hundred cords of wood per month as fuel, and in a well-wooded country, where the men can conveniently cut for themselves, much more is consumed. Every regiment requires, therefore, about eight or ten acres of woodland per month. An army of a hundred regiments will, in the course of a winter, denude several square miles of trees, so that (in the proportion which woodland generally bears to that which is cleared) a space of country equal to a county may be stripped of its timber. The men, having made themselves comfortable, are now called on to form working parties, and put the roads leading to the depots and the various camps in good order, generally corduroying them, so as to be passable during the winter; bridges are made over streams, drainage perfected, &c. In a few weeks, the chief portion of the labor of preparing a winter's camp is completed.
The sanitary regulations for camps are very stringent and comprehensive. The suggestions of experience as to the details by which the diseases incident to camp life can be prevented, are embodied in orders, and it is the duty of the medical officers and of the inspectors to see that they are observed. For instance, it is not permitted to have the floors of the huts lower than the external ground, and the men are required to keep pine boughs between their blankets and the earth. The method in which a camp shall be drained, and the offal disposed of, is prescribed. The cleanliness of the men is enforced. A rigorous system of reports upon these and many other particulars exists, so that negligences are corrected.
The military occupations which relieve the monotony of camp life are drilling and picketing. It is in the latter that officers and men find change and freedom, though it often involves severe exposure. The ordinary detail for this duty in a corps averages perhaps eight hundred to one thousand men, who are changed usually every three days. If the country be well settled, some opportunities are presented during that interval for intercourse with the 'natives;' but in Virginia, it must be confessed, the attractions of this kind are few. The secession ladies are not over well disposed to any wearers of Yankee uniforms, and though many of them are willing to bestow a few soft words in exchange for tea, coffee, and sugar, they are not liberal of social courtesies. The young man who joins our armies expecting to realize for himself the love adventures he has seen recorded in novels, will find the Southern ladies less given to romance than the damsels of Spain or Mexico. They are inclined, also, to be treacherous, as the fate of several gallant officers, who have gone stealthily beyond the lines to spend an evening with fair rebel sirens, and found themselves delivered to guerillas, has shown. Nevertheless, the experience of others never warns an adventurous youth, and opportunities frequently arise for practical jokes. During the winter of 1862-'3, while the army was encamped on the Rappahannock, an officer was fascinated by the charms of a fair widow who resided just beyond the lines, and frequently made evening visits to her. His companions, being aware of this, formed a party, on a bitter January night, and proceeding to the widow's house, surrounded it, and sending within some who were strangers to him, they announced themselves as belonging to the rebel army, and captured the enamored lover, blindfolded, led him out, and mounted him. Crestfallen and moody with, thoughts of his disgraceful situation, cursing, perhaps, the wiles of the enchantress, to whom he attributed it, he was made to ride many weary miles, and then, being dismounted, and the bandage removed from his eyes, he found himself at his own camp, where he was greeted with uproarious laughter.
