General Reno, who was Burnside's second brigadier, has made a reputation that will live forever in his country's history. At the battle of Roanoke the little general, but a month before a captain of ordnance, stood up fearlessly in the swamp amid his men, when they were lying down by his direction, and coolly gave his orders and encouraged them, entirely regardless of the balls flying round him on every side. In Pope's retreat, and amid disaster and defeat, he acquired new reputation by his skill, energy, and daring. A Virginian by birth, he was truly a loyal man; and, unlike some generals of our army corps, obeyed orders, and did all that could be done for the country and the general in command. His testimony that Pope's dispositions were good, if he had only been obeyed, should weigh much in that general's favor. After the victory of South Mountain, he was reconnoitring the enemy, when he fell by a random shot, which came, so those who were in the action say, from some soldier of our force. Lyon, Kearny, Reno, gone! Have we three such men left? General Park, an accomplished soldier, who particularly distinguished himself at the battle of Newbern, was General Burnside's third brigadier. The country will feel renewed confidence from his remaining with our new commander as chief of staff. On the morning we left the camp, a squad from a new regiment just arrived had been detailed for the guard at headquarters; one of the sentries was smoking his pipe as he marched up and down; another, who should have been patrolling his beat, was seated on the ground, cleaning his musket with a piece of wash leather he pulled from his pocket. The General was not near to stop these unsoldierly occupations. We came to the opinion that the boys in that regiment had never been to a country muster; but they were stout fellows and looked like fight.
