The 73rd Evacuation Hospital Unit was formed in 1940 in Los Angeles, California, and activated in 1942. In January 1943, the unit left the United States for the China-Burma-India theater, and in March arrived in Bombay after sailing via New Zealand and Australia. In the same month, it was transferred to Margherita to provide services to the engineering units building the Ledo Road as well as Chinese soldiers stationed around. In March 1944, the unit moved to Shingbwinyang in northern Burma and was stationed there until it was inactivated in July 1945. All medical officers were on the Attending Staff of the LAC/USC Medical Center and a majority of these were on the Staff of Good Samaritan Hospital.
