 By June additional forces, including 2d Battalion, 4th Marine Regiment as part of a newly activated Provisional Regiment, had arrived in China and been sent to Tientsin.By the time that force arrived the threat to the international settlement in Shanghai had eased and the combined forces of the American, British, Dutch, French, Italian, Japanese, Portuguese, and Spanish were seen as sufficient.The 4th Marine Regiment was reduced in strength in October 1927 with the 2d Battalion at Tientsin becoming 2d Battalion, 12th Marines and the Provisional Regiment dissolved.
