On January 11, 1919, the Mount Sinai Hospital affiliated unit, U.S. Army Base Hospital No. 3 was officially relieved of duty. The war was over for them. All told, they had treated 9,127 patients with 172 deaths (54 surgical and 118 medical, the latter due mainly to pneumonia related to the influenza epidemic that swept the world in 1918). On March 5th, the doctors and nurses returned to New York City. The enlisted men returned two and a half weeks later.
