The first Marine arrived at Quantico on May 14, 1917. At this time naval medical support began with the establishment of a Naval Post hospital. The post hospital delivered care and treatment in tents. In August 1917, this 100 bed hospital was relocated to nearby wooden barracks where the current Command and Staff College now stands. One month later the new hospital received its first cases of influenza, and what would later be named "Black Friday". The flu epidemic lasted until mid-December with more than 4,000 cases documented and 140 deaths. In 1918 the hospital bed capacity increased to 400 and seven other dispensaries were set up around the base. These eight facilities were staffed with 50 physicians, 24 nurses and 500 corpsmen.
