 Sometimes associated with 4th Marines is the paleontological and anthropological mystery of loss of the Peking Man fossils.The Chinese authorities requested the United States ambassador's help in evacuating the fossils and the custodians records indicate the fossils were crated and taken to the United States Legation in Peking.There a detachment of Marines, sometimes associated with the 4th but actually the Legation Guard Marines from Peking and Tientsin (North China Marines), were to escort the crates to the Marine compound at Tienstin and evacuated aboard "President Harrison" which was to evacuate remaining military and civilians.
