Events moved now with swift and terrible certainty.
Massachusetts attempted, on April 19, to send a regiment through the streets of Baltimore to invade the South, and the indignant wrath of her citizens could not be controlled by the mayor or police. The street cars on which they were riding across town to the Camden station were thrown from the tracks. The crowds jammed the streets and shouted their curses in the face of the advancing volunteers. Stones were hurled into their ranks and two soldiers dropped. A volley was poured into the crowd and several fell dead and wounded.
The crowd went mad. Revolvers were drawn and fired point blank into the ranks of the soldiers and those who were unarmed rushed to arm themselves. From Frederic to Smith Streets the firing on both sides continued with the regular crash of battle. Citizens were falling, but even the unarmed men continued to press forward and hurl stones into the ranks of the New Englanders.
The troops began to yield before the determined onslaughts of the infuriated crowds, bewildered and apparently without real commanders. They pressed through the streets, staggering, confused, breaking into a run and turning to fire on their assailants as they retreated.
Harassed, bleeding and exhausted, the regiment at last reached the Baltimore & Ohio station. The fight continued without pause. Volleys of stones were hurled into the cars, shattering windows and paneling. The troops were ordered to lie down on the floors and keep their heads below the line of the windows. Maddened men pressed to the car windows, cursing and yelling their defiance. For half a mile along the tracks the crowd struggled and shouted, piling the rails with new obstructions as fast as policemen could remove them. Through a steady roar of hoots, yells and curses the train at last pulled slowly out, the troops pouring a volley into the crowd.
In this first irregular battle of the sections the Massachusetts regiment lost four killed and thirty-six wounded. The Baltimoreans lost twelve killed and an unknown number wounded.
A wave of tremendous excitement swept the State of Maryland. Bridges on all railroads leading north were immediately burned and the City of Washington cut off from communication with the outside world. Troops were compelled to avoid Baltimore and find transportation by water to Annapolis. Mass meetings were held and speeches of bitter defiance hurled against the Federal Government. The Baltimore Council appropriated five hundred thousand dollars to put the city in a state of defense, though the State had proclaimed its neutrality.
The shrewd, good-natured, even-tempered President at Washington used all his powers of personal diplomacy to pour oil on the troubled waters of Maryland. In the meantime with swift, sure, and merciless tread he moved on the turbulent State with the power of Federal arms. It was impossible to hold the Capital of the Nation with a hostile State separating it from the loyal North.
The steps he took were all clearly unconstitutional, but they were necessary to save the Capital. They were the acts of a dictator, for Congress was not in session, but he dared to act. Troops were suddenly thrown into the city of Baltimore and its streets and heights planted with cannon. The chief of police was arrested and imprisoned, the police board was suspended and the city brought under the rule of drumhead court-martial. The writ of habeas corpus was suspended by Federal authorities in a free and sovereign State whose Legislature had proclaimed its neutrality in the sectional conflict. Blank warrants were issued by military officers and the house of every suspect entered by force and searched. The mayor and his Council were arrested without warrant, held without trial, and imprisoned in a military fortress, and when the Legislature dared to protest, its members were arrested and its session closed by bayonets.
So thoroughly was this work done that within thirty days from the attack on the troops of New England, Maryland's Governor by proclamation called for four regiments of volunteers to assist the Washington Government in the proposed invasion of the South.
