THE FOURTH MARINES IN SHANGHAI, CHINA
While Shanghai is rapidly changing with old buildings giving way to new buildings, there are still many places remaining related to the Fourth Marine regiment's long presence in the city from 1927 to 1941. The 1st and 3rd Battalions of the regiment were deployed to Shanghai in 1927 to protect American citizens and property in Shanghai's International Settlement (the "Settlement") on the Puxi or west side of the Huangpu River (then called the Whampoo River). The 2nd Battalion was deployed to Tientsin, China at the same time and redesignated into another regiment. The 2nd Battalion of the Fourth Marines was reactivated in Shanghai on September 18, 1932 in order for the regiment to be at full strength to effectively defend the U.S. defense sector of the Settlement. The 3rd Battalion was deactivated in Shanghai on December 19, 1934.
