From each brigade an assistant surgeon was detailed to provide food and shelter for the wounded. His duty was to superintend the erection of hospital tents as soon as there was a prospect of an engagement, and to have hot coffee and rations of food ready for the wounded as soon as they came to the hospital; he was to attend to their clothing, bedding and rations as long as they remained in the hospital.

Another assistant surgeon from each brigade was selected to keep the records; to take the name and character of wound of every one who was brought to the hospital, with the operation, if any; and the list of deaths, the place of burial, and all other matters necessary to record. An assistant surgeon was to remain with each regiment, and attend to getting the wounded from the field into the ambulances, and to arrest hemorrhage in case of necessity.

Thus, all labor was systematized. Every officer and nurse knew exactly what to do: each had his own part of the work assigned to him, and there was no conflicting of orders or clashing of opinions.

Our ambulance system was also very perfect—so complete, indeed, that, after a year of trial in the Army of the Potomac, congress adopted it as the ambulance system of the United States. To Doctor Letterman, also, belongs the honor of originating this system.

The ambulances of each corps were under command of a captain, who acted under directions from the medical director of the corps. A lieutenant commanded the ambulances of a division, and a second lieutenant those of a brigade. To each ambulance was assigned a driver, and two stretcher-bearers; and to three ambulances a sergeant, mounted. The ambulances of a division always went together, behind the division, and on the march were attended by a surgeon, an assistant surgeon, a hospital steward, a cook, and three or more nurses, who were to attend to the wants of the sick in the ambulances, and at night, if any were unable to return to their regiments, to erect tents for them, and supply them with food and bedding. In an engagement, the stretcher-bearers of each regiment, with the sergeant, reported to the assistant surgeon in attendance with the regiment. As soon as a man was wounded, he was brought to the medical officer, put into an ambulance, and taken to the division hospital. By this means, ordinarily, every man was carried to the hospital of his own division.

The improvements in the quartermasters' department were nearly as great; and we have already alluded to the abundant supplies furnished by the commissary department.

Great difficulty was experienced by the troops of our corps in getting wood. The men of our Second division lugged wood on their backs a mile and a half, with which to do their cooking and warm their tents. But notwithstanding the hardships they endured, the inclemency of the winter, and their severe picket duty, the men were gay. In many of the regiments, the sounds of the guitar and accordion could be heard every evening; and on pleasant afternoons and evenings, parties assembled in the company streets and danced cotillions, and polkas, and jigs, to the music of violins. When snow covered the ground, mimic battles with snowballs were a frequent amusement. At times, one regiment would challenge another, and a general melee would follow. Snowballing was, particularly, a favorite amusement with our friends of the Twenty-first New Jersey, who never let an opportunity pass for indulging in their favorite sport. Each party carried its flags and was led by officers chosen for the occasion. The capture of a flag, or of a number of prisoners, from an opposite party, caused great glee among the victors. A good deal of interest was excited throughout the Second division by a snowball battle between one of the Vermont regiments and the Twenty-sixth New Jersey. Both regiments formed in line of battle, each officered by its line and field officers, the latter mounted. At the signal, the battle commenced; charges and counter-charges were made, prisoners were taken on either side, the air was filled with the white missiles, and stentorian cheers went up as one or other party gained an advantage. At length victory rested with the Vermonters, and the Jersey boys surrendered the field, defeated.

Another favorite amusement in the corps was the game of base ball. There were many excellent players in the different regiments, and it was common for the ball-players of one regiment or brigade to challenge another regiment or brigade. These matches were watched by great crowds of soldiers with intense interest.

In our Seventy-seventh regiment, matters went on much the same as in other regiments of the corps. We had our share of disease and desertions. We had our ball-players and our violinists; our singers and our story-tellers, as every regiment had. At regimental head-quarters, matters went on gaily. It was the custom of the officers of the field and staff to collect in one of the tents as evening came on, and, in company with friends from other regiments, pass the hours in lively converse, in singing and relating amusing stories.

We had a glee book and an old copy of the "Carmina Sacra," and then our friend, Colonel, now Major-General, Connor, was never at a loss for a song, and Colonel French often displayed his genius with the violin, and our friend, the chaplain, could always tell a good story or perpetrate a joke. Chaplain Norman Fox was an accession to our staff, who joined us when we first encamped at White Oak Church. He was a gentleman of enterprise and talent, who, soon after his arrival in camp, instituted a series of religious meetings on week days, in addition to the regular services of the Sabbath, and a good deal of religious interest was awakened among the men.
