The Trial of the Lincoln Conspirators Lecture and Film

Saturday June 13, 2015

Monocacy National Battlefield will hold a two-part special event on the trial of the conspirators in the Lincoln assassination. At 4:00 p.m. at the Thomas House, Joe Brooks, a retired lawyer and park volunteer, will present a lecture deconstructing the conspirator’s trial. Rather than focusing on the question of the conspirators’ innocence or guilt, the talk will provide a different perspective by examining the legal mechanics of the trial. Some of the fascinating issues explored in the talk include whether the defendants should have gone before a civilian court instead of a military tribunal, how laws affecting the trial differ from present day laws, and why General Lew Wallace (Union Commander at the Battle of Monocacy) and his fellow commissioners were chosen for the tribunal. Space is limited and advanced registration is required. Please call the park’s visitors center at 301-662-3515 to register.

Later that evening, at 7:00 p.m. the park will use the historic Thomas Barn as a venue for screening The Conspirator , the film is rated PG-13 and runs 122 minutes. Feel free to bring a snack and comfortable lawn chair. Seating will be inside the barn but open air, so dress accordingly. The event will take place rain or shine, and no registration is required.  Between events, visitors are encouraged to enjoy the battlefield’s trails and historic scenery. Picnic tables are available at Gambrill Mill and the Visitor Center. All events and activities at the park are free. Parking for both events is located at the red Thomas Barn at 4460 Baker Valley Road. For more information, please visit the park’s website at
