Flotilla Service Act was a United States federal statute passed on April 16, 1814 preceding the British Royal Navy blockade of the New England Colonies commencing on April 25, 1814. The public law established a temporary Mid-Atlantic naval auxiliary service for amphibious operations orchestrated by the Chesapeake Colonies during the War of 1812. The Chesapeake Bay Flotilla conducted amphibious maneuvers in low-level tidal creeks seeking to deter the territorial headway of the British Royal Navy offensive into the Chesapeake Bay tributaries. The Act of Congress authorized appropriations for the federal law in response to the foreseeable onslaught by the British Army redcoats arson offensive on August 24, 1814 at Washington City better known as the Burning of Washington.
