Las expediciones rusas, 1917-1920

At the beginning of 1917, the Allied coalition in World War I was in crisis as German pressure pushed the war-weakened Russian Empire to the brink of collapse. The other allies tried to prop up the shaky Russian government as it fragmented internally in the months that followed. It finally fell in November 1917 with a new regime replacing it that promised to get out of the war. Desperate to hold the Eastern Front against the Central Powers, the Allies decided to intervene. However, with their resources employed elsewhere, they needed a source of military forces for their deployment to Russia. After continued Allied calls for help, President Woodrow Wilson reluctantly agreed in July 1918 to provide American troops for two expeditions. Wilson's goal was to placate the Allies without intervening in Russia in any major way.
