Completed in December 1900, Battery Gregg was the fourth of Fort Mott’s five batteries to be constructed. This battery contained emplacements for two 5-inch rapid fire guns (model 1900) mounted on pedestal mounts with shields. Both guns were not mounted at the battery until 1906. In 1913, they were removed and later shipped to Benica Arsenal, California.

Fort personnel reported that when the guns were installed, the field of view was obstructed by newly planted trees on the reservation., Battery Commander’s Station. , By 1920 the Battery Commander’s Station was built to direct the fire of the 10-inch guns in Battery Harker.
