The fort's size grew during its lifetime, beginning with the Spanish-American War. The 4th Artillery was transferred to another location and the 5th Infantry Division took its place. During World War I, a military hospital was established and an adjacent military installation, Camp Jessup, was built to accommodate the influx of new troops. The size and scope of the fort increased again before and during World War II, including the establishment of the fort as a major command post
The military decided to close the fort as part of a realignment and closure plan. In May 2017, the organization in charge of the fort chose a master developer. Additionally, actor and filmmaker Tyler Pyler bought some of the land to build a new film studio.
