In the afternoon came drills, sometimes of regiments, sometimes of brigades, and the unfailing dress parade. There were a few regiments of new levies just arrived, a thousand strong; all provided with overcoats, and looking finely in their new, clean clothes—quite a contrast to the old soldiers. In one of the old regiments on brigade drill we saw an officer, probably a sergeant, in a checked knit undervest, his neck and part of his arms bare—commanding a company. A sentry on guard before the quarters of the general in command, had great holes in both elbows of his dirty jacket, and his shoes were untied. The brigades were generally of five regiments, a new regiment being one, and composing fully two fifths of the line. It is not wholly, however, by the casualties of the battle or the greater losses from exposure, overwork, and disease, that the regiments are diminished. If a good blacksmith is found, he is detailed to the forge; others are detached as ambulance drivers, or as hospital attendants or clerks. This thins the ranks of the old regiments. It is surprising, however, to see how much better the veterans will bear exposure than men coming fresh from home. The old regiments were frightfully diminished by disease on the Peninsula; but I saw very few that could not rally more men than the 35th Massachusetts, that had been out of the State only a little over a month. They had but three hundred men of the original thousand. They left Washington without their knapsacks; and had marched without even the shelter tents, officers and men alike bivouacking on the ground, wearing the same clothes without a change. The long marches, the exposures, the excitement of battle, and the unaccustomed food had disabled four hundred men; some of them undoubtedly never strong enough to have enlisted, and who should have been rejected by the examining surgeons. The old regiments, who had gradually been hardened to this life, and who had learned to thrive on the soldier's fare, lost comparatively few in this way.

The brigade drills and the manœuvres in line were not so well executed as we expected. There was no practice in firing at a mark; probably from a want of ammunition. From accounts of officers on the field of battle, it certainly is the case in our army that some of the fresh soldiers will fire in the air, and even close their eyes. The Hythe system, as now taught in the English army, and among the rifle clubs, makes excellent marksmen; and the greater part of the instruction is without the use of powder. It is a pity it cannot be more extensively introduced in our army.

One does not expect to find the same training before the enemy as in the great French camps of instruction. It was my good fortune to visit the camp of a portion of the great Crimean army. The privates, besides their military drill, were exercised in running, leaping, fencing, and boxing; and some sergeants were teaching dancing. I followed a regiment of the chasseurs of Vincennes to their field of drill. For an hour or two they went through different manœuvres by the bugle, performing many of the movements at the double quick. Then came a rest; as soon as that was ordered, the fine band of the regiment came forward and struck up a lively dance, to the tune of which several of the privates amused and refreshed themselves by waltzing round the field.

Returning, however, to our picturesque camp in this charming valley. There was no more striking scene than when darkness came on and the thousand camp fires and lights in the tents were all in sight. The rail fences, bought by the thoughtful quartermaster, and paid for as an army supply, were used as fuel; a truly considerate act, for a quartermaster can buy fuel for the army, but he cannot pay damages done to property. This same ground, now covered by our troops, had been camped over by Lee's army; who had also used the fences, not even paying for them in the worthless Confederate scrip. Soon after dark, the bright lights of the signal corps appeared on the mountain north of the Maryland Heights, and messages were sent to McClellan's headquarters. Flags are used in the day, and at night lanterns. The signal officer has two lights; they are held one above the other, the lower one being stationary; moving the upper light to the right means number one; moving the light to the left, number two; moving first to the right and then to the left, number three; by lowering the upper light in front of the under one, a fourth signal is given; and so on. There are about five numbers; and by the different combinations of these five numbers, there is made a great number of signals, which can be read by the officers who have the key. The mode is much the same as that used by our mercantile marine with their signal flags. The signals are given very rapidly, and a few minutes suffice for the sending of the messages.

Evening is the time for talk around the camp fires; and the conversation often turns upon our rebellious brethren. Among our regular officers you meet the classmates and old companions in arms of the rebels, and hear of little traits and peculiarities that only intimate acquaintances can relate. Civilians who had known General Lee at Washington, have spoken of him as very formal, and rather pompous in his manner, giving the impression that he was a man of more show and pretence than abilities. We learned here, however, that, in Texas, or California, where he was for a long time before he took his high position on Scott's staff, he was famous for marching his men without the usual encumbrances of baggage, on the most severe expeditions against the Indians, in the snow and cold of the winter. Stonewall Jackson has always been famed for his peculiarities. When a young man, he was possessed with the idea that he was in danger of having his limbs paralyzed, and he would pump on his arm for many minutes, counting the strokes, and annoyed beyond measure by the interruptions of his companions breaking up his count. Our officers, both regular and volunteer, who have been in actual battle, have a great respect for the rebel leaders and soldiers; they speak very highly of their drill, and believe that straggling exists to a less extent among them, in battle, than with us. From the rebel newspapers I should doubt whether this is the case. One thing we have not considered, which has given the rebels a great advantage in this contest. It is the large number of military colleges in the South; not like our few private schools at the North, but well-endowed academies. In the summer of 1860, immediately before the election of Lincoln, I visited the military academy at Lexington, Virginia. It was supported at the expense of the State, with two hundred and more pupils, coming from the different counties in proportion to their population. They were practised in the actual firing of cannon and mortars; and every afternoon were drilled as infantry for about two hours, much of the time at the double quick. The principal was a graduate of West Point; and he was assisted by a respectable board of instructors. A good civil and military education, after the mode of instruction at West Point, was afforded to the students. This institution had been in existence for years; and one can readily appreciate the advantage that Virginia has in this war from the graduates of this school. Alabama and several other of the Southern States have similar colleges; while we at the North have been obliged to educate all our volunteer officers by actual service.

The morning Stuart with his cavalry left Chambersburg, we rode forth for the battle field of the Antietam. We noticed the disappearance of some of the camps of the infantry brigades. We knew of the patrolling of the cavalry along the road we were pursuing, and found the picket guards farther out, and passes and countersigns necessary where before we went unchallenged. We were several hours in getting to the battle field, and stopped to get some refreshments at a large brick farmhouse, where the battle on the left began. The hospital flag was still flying over the building, though no patients had been there for a day or two. Twenty-seven died in that one farmhouse from wounds received in that bloody fight. On the night of the battle, cows, sheep, poultry, and fences disappeared before our cold and hungry troops. But since then, though the house was in the neighborhood of several camps, the old lady and her daughters, who alone were at home, had been undisturbed, except by the small pilferings of stragglers.

The great battle has been so well described by the correspondents of the newspaper press, and by those who were over the field before we were, that I shall only mention a few incidents to which our attention was called. The principal contest was on the right, west of the Antietam river. Here Hooker with his army corps began the battle, and fought so long and splendidly. Both armies crowded their forces to this part of the field. Sumner, whose troops had been with their belts on since three in the morning, brought up his large corps, drawn up in three columns, forty paces apart, to reënforce Hooker's hard-pressed soldiers, who were retreating before the fresh and overwhelming reënforcements of the enemy. In less than an hour, the whole of Sumner's corps was swept back, broken and entirely routed, and never appeared in the field again; the column in the rear not being in position to fire a gun, but losing as many men as those in front.

The manner in which General Sumner brought his troops into action has been severely criticized, even by officers of his own corps; whether justly or not, it is difficult to decide. No commander was more confided in by his soldiers than Sumner. 'He has risen from the ranks, and been through all the grades of the service,' 'He knows how to treat his men,' were expressions constantly heard. General Hooker's reputation as a fighting general was admitted everywhere; his coup d'œil of the battle field was represented as most excellent.

It was also on the right that the desperate fighting in the woods and the deadly struggle at close quarters in the cornfield with such fearful loss of life took place. An officer who was on the battle fields of Magenta and Solferino, says that the scene here was much more horrible. Many spoke of the scenes they saw with a shudder. They could not throw off the impression made by the masses of wounded and dead; the wounded often lying neglected and helpless under the dead, sometimes crushed to death by the wheels of our own artillery.

Our left at Antietam was far off from the right: in these days of guns of long range the line of battle is longer than it was formerly. At Waterloo the English occupied a front of less than two miles. In this battle ours was about four miles. In the battle of Solferino the engagement extended for eighteen miles.
