 The 4th regiment settled into routine garrison duty during which it gained the nickname "China Marines" and a unique feature, the only fife and drum corps in the Corps.The formation of the Fessenden Fifes was a result of influence of the American chairman of the Shanghai Municipal Council and Civil Commandant of the Shanghai Volunteer Corps, Stirling Fessenden, and instruments from the 1st Battalion, Green Howards whose fifers and drummers taught the Marines to play.Reductions continued and on 14 January 1928 the 4th Regiment was detached from the withdrawing Marines of the brigade and on 13 February 1930 the regiment gained its designation as 4th Marines.
