This subject, like many of the periods of the Civil War, has been often described, and is familiar to .the passing generation, but has, I believe, never before been placed upon your records, ,nor by an eye witness. Therefore, I venture to present it here. TheTwentieth Massachusetts Regiment of Volunteer Infantry, in which I had the honor to be a First Lieutenant and Adju- tant, left Boston in the Autumn of 1861, for active service with the army. It was commanded by William Raymond Lee, as Colonel,-a West Point graduate. Paul J. Revere was the Major. It had been, before the date of the Balls Bluff engagement, but a few weeks in the ser- vice, and was stationed first at Wash- ington, where I remember calling with Colonel Lee, who knew them, upon Gen- eral Scott, then commanding the Armies of the United States, and upon General McClellan, then Commander of the Army of the Potomac. The men of the Regiment, like all of the troops in the East at that time, were un- trained by battle, never having heard the sound of a hostile bullet, and were of no more value as soldiers than were the Mi- litia Regiments. Soldiers are not soldiers until they have been long enough together to have acquaintance with and respect for their officers, and have learned obedience with a belief in discipline, with a willingness to abide by it. The earlier Battle of Bull Run, which became a rout for want of discipline, proved nothing and taught nothing except the after-thought of the necessity of discipline. Up to this time 1861, the important arms of Cavalry and Artillery had been almost entirely neglected, most of the Cavalry not yet being armed or equipped. General McClellan, who was in command when we joined the Army of the Potomac, was a thoroughly educated soldier. Soon after his graduation from West Point, he was employed in the construction of the first Pacific Railway. Later he was selected as one of a Commission to study the Art of War in Europe. For a time he was with the Allied Armies in the Crimean War, with every possibility of instructing himself in siege operations, construction of military bridges and use of pontoons, and the accepted order of battle for the different arms of the service. Always occupied with matters of large importance, and with all these military experiences, he became the best equipped man for the command of the Union Army. General McClellan was the most popular Commander that the Army ever had. The men thoroughly believed in him. Certainly the country owed much to him for the thorough organization of the Army, which enabled less qualified Commanders, before the time of Meade and Grant, to accomplish some- thing with it. The Twentieth Massachusetts Regi- ment was attached to General Stones Corps of Observation, and was encamped near EdwardsFerry on the Potomac River, some three miles from Balls Bluff. General Stone was an accomplished soldier and we all respected him as such. We were part of the Brigade of General F. W. Lander. I had known him well in Salem, where our families resided. He had had a most adventurous life as an explorer, having once crossed the continent from San Francisco to the East, alone, his companion having died on the journey. His courage was unquestioned, and he had military ability... --This text refers to an alternate Paperback edition.
