Leaving the scene of conflagration behind, Lieutenant Jones made a hurried march toward Hagerstown, Maryland, wading through streams and swamps, and reached that place at seven o’clock on the morning of the 19th. There he immediately procured means of conveyance, and started for Chambersburg, Pennsylvania, which he reached in the afternoon in an exhausted condition. The men were covered with mud and dirt, and were overcome with fatigue and hunger, having eaten nothing since leaving Harper’s Ferry. They were hospitably entertained by the inhabitants, and departed in the afternoon train for Carlisle barracks. Lieutenant Jones and his men received the approbation and thanks of the Government for their judicious conduct on this occasion, and he was commissioned Assistant Quartermaster-General, U. S. A., with the rank of Captain. The arsenal buildings were immediately taken possession of by the rebel authorities, and used for the purpose of making and repairing arms, until they again came into possession of the Federal authorities. THROUGH BALTIMORE. A terrible civil war, destined to be without parallel for bitter intenseness, was now fully revealed. The curtain that had so long screened the enemies of the Union in their machinations against the Government, had been raised at Fort Sumter; and in the seizure of Harper’s Ferry arsenal, although its usefulness to them had been seriously impaired by the true hearts and hands that applied the torch, and rendered the darkness of night lurid with its conflagration, desolation and ruin had already began their march, leaving their footprints in ashes among the lovely scenes of civilized life, and rioting amid the legendary grandeur and time-honored places of the Old Dominion. It needed but one act more to encircle us with the thunders of war—to plunge the nation into an almost fathomless ocean of civil hatred and revenge, and leave upon the pages of history the unhappy record of many an ensanguined field. The green sward of a happy, prosperous and free land only remained to be crimsoned with blood! The heart of some martyr freemen needed only to be drained of its life-blood, and the stripes of our old flag dyed a deeper crimson in the precious flood. Soon, too soon, alas! this last fatal act was accomplished. The day after the burning of Harper’s Ferry saw the streets of Baltimore red with sacred blood, and a nation shuddered as the lightning spread the fatal news from State to State.
