 The three 50 caliber guns stored at Augusta, GA were deployed to San Juan, Puerto Rico, although apparently only two were mounted, both at Fort Brooke, as Castillo San Felipe del Morro (often called "Morro Castle") was known at the time.Following the war, all 4.7-inch weapons were withdrawn from service by the end of 1920, and all were disposed of by 1927.Other weapons deployed in limited quantity were also retired during this period.
