Changes

'''Battery Cullum''' and '''Battery Sevier''', completed by [[1898]], housed four 10- inch rifles on disappearing carriages. Although these structures appear to be one large complex, they are two separate structures.<ref name="NPS" /> After World War I, the batteries were declared surplus and two of the guns at Battery Cullum were removed. However, in [[1921]], the War Department reversed that decision and installed two new 10-inch guns at Cullum. Between [[1922]]-[[1923]], a new power station was constructed at Cullum/Sevier. In [[1942]], the 10-inch guns at Batteries Cullum and Sevier were removed. They were replaced in [[1943]] by three-inch rapid fire guns.<ref>de Quesada, Alejandro M.
