To Colonel D. Hassendeubel of the 3rd Missouri Volunteers: "In respect to your report upon Arms and the movements of the secessionists, in your vicinity and at Manchester, it is important that you keep us fully advised as possible." Written ten days after the "St. Louis Massacre," when troops under Lyon's command opened fire on a crowd of St. Louis citizens, injuring 90 and killing 28. Lyon, credited with stopping the Missouri secessionist movement, was the first Union general killed in the Civil War, in August 1861 at the Battle of Wilson's Creek.
