In 1915 a battalion of the 3rd Regiment of Tonkinese Rifles (3rd R.T.T.) was sent to China to garrison the French Concession in Shanghai. The "tirailleurs" remaining in Indochina saw service in 1917 in putting down a mutiny of the "Garde Indignene" (native gendarmerie) in Thai Nguyen. In August 1918 three companies of "tirailleurs tonkinois" formed part of a battalion of French Colonial Infantry sent to Siberia as part of the Allied intervention following the Russian Revolution.
