"The Bouquet Battery, commanding the viaduct over the Patapsco River, on the Baltimore and Ohio Railroad, near the Relay House, in 1861. The Relay House was a small railroad station about seven miles from Baltimore, on the Northern Central Railroad. It was of small population and trade, but its position elevated it into considerable importance. Immediately after the troubles in Baltimore this position was seized upon, and General Butler made it his headquarters, and by so doing not only held the control of the railrod to Harper's Ferry and the Baltimore and Ohio Railroad and Patapsco River, but threatened the city of Baltimore with a strong military force. The Relay House was romantically situated in a country of exquisite natural beauty. Our sketch shows the battery stationed to command the viaduct, with the Relay House in the distance." —Leslie, 1896
