On Thursday, April 24, this regiment reached Washington, having taken the cars at the junction. They were followed directly by their noble comrades of the march, the Massachusetts Eighth, and immediately moved into quarters. While the troops under Butler and Lefferts were lying at Annapolis, great anxiety was felt regarding them at Washington. The lamented Lander was then at the capital, pleading for the privilege of raising a regiment for the defence of the government, but, for some inexplicable cause, General Scott had not yet accepted his services. With Baltimore in open revolt, and Annapolis doubtful in its loyalty, this anxiety about the troops become so urgent, that Lander was sent forward to Annapolis, with general directions to aid the troops with all his ability, and to direct Colonel Butler not to land his men until the kindly feeling of the citizens of Annapolis was ascertained. Lander started on the mission, as he undertook everything, with heart and soul. He rode from Washington to Annapolis on horseback, without stopping for darkness, or any other cause save the necessary care of his horse, and reached Annapolis an hour after the troops had landed. Bringing his experience, as a frontiersman, who had seen hard service against hostile Indians on the plains, to bear on the position, Lander gave Colonel Butler such aid and advice as assisted greatly in bringing the soldiers forward with less danger and suffering than might otherwise have arisen during their march to the junction. MARYLAND. The attack by an armed mob upon the Massachusetts regiment had called the attention of the entire country to the State of Maryland, and her future course was the subject of deep feeling. Indirectly, Washington was, of course, menaced by her movements, and it became a matter of vital importance that she should be retained in the Union and restored to her fidelity. Not here alone were keen eyes watching her future. England and France, in their eager thirst for dominion and their jealousy of America and her liberal institutions, scrutinized every action, with reference to their own future course. Second only to Washington, therefore, for the time, became the “Monumental City.” [Illustration: UNION HEROES BURNSIDE. HEINTZELMAN. BUTLER. WOOL. McCALL.]
