A crowded rally held in support of the Union cause was illustrated in Harper’s Weekly. The event included an address by President Lincoln, music by the Marine Band, and a reading of the District of Columbia’s official resolutions regarding the Civil War. The stage erected on the East Front of the Capitol sported decoratively arrayed gas lighting, which illuminated the evening event.
