Major Birney's discipline was not confined to camp life, and the drill ground. It extended as well to the march. Every morning on the march the regular detail for guard duty was made, and this detail, under command of the officer of the day, marched at the rear of the column, and proved an efficient preventive to "straggling," a habit exceedingly demoralizing to an army on the march. If any fell sick or gave out by the way they were taken charge of, and if possible, were placed in an ambulance, or in the absence of such, in one of the regimental or brigade wagons. If canteens needed replenishing a detail was made from each company to perform that duty. If foraging was to be engaged in it was done in the same methodical manner, and this was not infrequent, for the major was a strong believer in the doctrine of the rights of the army to live off the products of the enemy's country, but it had to be done "decently and in order." When on the march, if an obstruction was encountered, the head of the column was always halted until all had passed the obstruction and the ranks closed up. By this means the men in the rear were saved the necessity of moving at a "double quick" to overtake those in advance, a duty very exhausting, and as a consequence the command was always kept in compact order and could, with less fatigue, march twenty miles a day than ten by the old "go as you please" methods so common while on the march. During our army's encampment at Harrison's Landing the Confederates were quiet and only deigned to make their presence known on one occasion and that was in the way of a night surprise, sending by way of a reminder that they were yet alive and alert, a number of shells across from the heights on the south side of the river. This piece of pleasantry was replied to promptly by our batteries, and the next day arrangements were made to prevent a repetition by sending a division of infantry under General Butterfield over to that side and taking possession of those hills for ourselves. On August 12th the 57th was transferred from Jameson's old brigade (the 1st) to General D. B. Birney's (2d) brigade. General Jameson was injured by the falling of his horse at Fair Oaks and died from his injuries the following November. He was one of the finest looking officers in the army. General J. C. Robinson succeeded him in command, and led the brigade in the seven days' battles. General Birney was one of the original brigade commanders of Kearny's division. His brigade now comprised the following regiments, viz: the 57th and 99th Pennsylvania; 3d and 4th Maine; 38th, 40th and 101st New York. There were seven regiments, but numerically, they scarcely exceeded the strength of two full regiments.
