On the ninth of July, while at section drill, a sad accident occurred, by which Corporal Morse (Nathan T.) and private Bourne (William E.) lost their lives, and private Freeman (Edward R.) was very seriously injured. From some unaccountable cause the limber chest upon which they were mounted exploded, almost instantly killing Morse and Bourne and severely injuring Freeman. The remains of Morse and Bourne were escorted to the depot by the company, and there was extended to them a marked tribute of respect upon their arrival and burial at home. On the sixteenth of July the battery left Camp Clark at half past one o'clock in the morning, with the First and Second Rhode Island Regiments, but it was broad daylight before the command got fairly away from the vicinity of the camp. Under the lead of Colonel Ambrose E. Burnside, who had command of the Second New Hampshire, Seventy-first New York, First and Second Rhode Island Regiments and the battery, as a brigade, the company marched over Long Bridge to a point about ten miles from Washington, where the whole brigade bivouacked for the night. The next morning the march was resumed at day-break, and Fairfax Court House was reached about half past one in the afternoon. The battery was parked and the company went into camp near the Court House, on the ground and near the residence of a Mr. Stephenson, an English gentleman with a large and interesting family, every member of which appeared to do their utmost to promote our comfort. Early the next morning, Thursday the eighteenth, the advance again began and continued with numerous delays until near night-fall, when camp was established near Centreville, on the plantation of a Mr. Utteback. On the morning of Sunday the twenty-first the brigade broke camp and commenced the march towards Manassas. The march was a tedious and lonely one until daybreak. The morning broke as clear and lovely as any that ever opened upon Virginia soil. In the early daylight it seemed to dawn upon the minds of both officers and men, that they were there for a fixed purpose, and that the actual business of their vocation was to commence. Previously, nearly all had thought that upon the approach of the United States troops, with their splendid equipment and the vast resources behind them, the "rebel mob," as it was deemed, but which we afterwards learned to respect as the rebel forces, would flee from their position and disperse.
