The passage of trains through Baltimore at that period was by horse power across the city, from one depot to another. The horses being quickly attached as soon as the locomotive was taken off, cars carrying about two-thirds of the regiment were driven rapidly over the route; but to intercept the remaining four companies the mob barricaded the tracks, and it became necessary for these to abandon the cars and cover the remaining distance on foot. At once they became the target for showers of stones thrown by the mob, and in order to lessen the need of armed resistance, the officers gave the order to proceed at the double-quick. It was a mistake, but a common one when citizen soldiers are dealing with a mob; the most merciful as well as the wisest course being to scatter the mob promptly by a warning, followed by the promised volley. The mob thought they had the troops on the run, and were encouraged to believe that they either dared not shoot or that they were without ammunition. The missiles were followed with pistol shots, at which one soldier fell dead. Then the order to fire was given to the troops, and several of the crowd, rioters and spectators, fell. The mayor of Baltimore joined the officers at the head of the column, to give his authority to its progress, and also to tell the officers to {24} defend themselves. Instead of being faced about to confront the mob, the troops were marched steadily forward, turning about as they advanced and delivering a desultory fire, which, however, did not deter the mob from continuing its attack. At last, Marshal Kane, of the Baltimore police, interposed with a company of policemen between the rear of troops and the rioters, formed a line, and ordered the mob back on penalty of a pistol volley. This was so effective as to practically end the affair, and without further serious disturbance the detachment joined their comrades at the Camden station, and boarded the train that took them to Washington. The regiment's loss was four killed and thirty-six wounded. The men were furious over the affair, and it required all the authority of the colonel to keep them from leaving the cars and taking vengeance on Baltimore for the death of their comrades. Arrived at Washington, the first regiment to come in response to the call of the President, they were quartered in the Senate Chamber. [Illustration: EPISCOPAL CHURCH, ALEXANDRIA, VA.
