After the bloodshed in Baltimore, involving Massachusetts troops which were fired on while marching between railroad stations, on April 19, 1861, Baltimore Mayor George William Brown, Marshal George P. Kane, and former Governor Enoch Louis Lowe requested that Hicks burn the railroad bridges leading to Baltimore, in order to prevent further troops from entering the state. Hicks reportedly approved this proposal. These actions were addressed in "Ex parte Merryman", the famous case of Maryland militia Captain John Merryman who was arrested by Union forces.
