The eastern half of Carroll Island was used as a testing location for open air static testing of chemical weapons since the 1950s. During tests of chemical agents and other compounds at Carroll Island, Maryland, from July 1, 1964, to December 31, 1971, nearly {{convert|6.5|ST}} of chemicals were disseminated on the test area including {{convert|4600|lb}} of irritants, {{convert|655|lb}} of anticholinesterase compounds such as the nerve gasses [[Sarin]] and VX, and {{convert|263|lb}} of incapacitants such as LSD. Simulant agents, incendiaries, decontaminating compounds, signaling and screening smokes, mustard, and herbicides were also released as well as riot control gasses. The test sites consisted of spray grids, a wind tunnel, test grids, and small buildings.<ref name="Albright2013">{{cite book |author=Richard Albright |title=Death of the Chesapeake: A History of the Military's Role in Polluting the Bay |url=https://books.google.com/books?id=dGGPq10wa3YC&pg=PT82 |access-date=October 1, 2013 |date=May 29, 2013 |publisher=Wiley |isbn=978-1-118-75666-9 |pages=82– }}</ref>

Fort Hoyle was established on October 7, 1922, and was created from a portion of the Edgewood Arsenal. Named for Brigadier General [[Eli D. Hoyle]], who had commanded the [[6th Field Artillery Regiment]], the post was home to Headquarters, 1st Field Artillery Brigade (1922 to 1939), the 6th Field Artillery Regiment (1922 to 1940), the 1st Ammunition Train (1922 to 1930), and the 99th Field Artillery Regiment (minus 2nd Battalion) (1940 to 1941).
