Most of these troops were withdrawn in November 1941, however some of them were scheduled to be withdrawn on December 10. The remaining Marines who were the Marine Embassy guards, as well as some US Navy support personnel, for a total of 204 men, were captured by the Imperial Japanese Army and forced into slave labor until they were freed in 1945. Later, another group of Marines also referred to as China Marines were those of the 1st and 6th Marine Divisions sent to occupy northern China after the surrender of Japan and the end of World War II from 1945 - 1948.
