Union artillery emplacements on Federal Hill

Description

View of Union soldiers with cannons at Federal Hill in Baltimore, Maryland, during the American Civil War. In 1861, the 6th Massachusetts Militia and members of Cook's Light Artillery of Boston occupied Federal Hill under the command of General Benjamin F. Butler. The troops set up a number of cannons directly pointed at Baltimore's central business district across the harbor in an effort to secure the allegiance of Baltimore, and the greater state of Maryland, to the North.
