The British and French did not have enough soldiers, so the asked the United States to help. They asked the U.S. to send soldiers to both the North Russia Campaign and the Siberian Campaign. President Wilson agreed in July 1918 even though the War Department said not to help. The U.S. sent two groups of soldiers: 5,000 soldiers were the American North Russia Expeditionary Force (nicknamed the Polar Bear Expedition); and 10,000 were called the American Expeditionary Force Siberia. In the same month, the Russian White movement asked the Beiyang government of the Republic of China to send men. They sent 2,000 soldiers by August. The Chinese later occupied Outer Mongolia and Tuva. They sent a battalion to the North Russian Campaign to fight against the Bolsheviks.
