How did the American expeditionary forces help the allies win the war
The American Expeditionary Forces (AEF) significantly contributed to the Allies' victory in World War I in several ways:
1) Provided fresh troops: The AEF sent fresh troops to the allied front lines that helped to energize the allies and turn the tide of the war.
2) Improved morale: The arrival of American troops boosted the morale of the Allied forces as they faced a declining spirit after years of war.
3) Advanced military tactics: The AEF brought to the battlefront innovative tactics and advanced weaponry that helped to break the trench warfare deadlock that the allies faced.
4) Provided critical resources: The US provided munitions and supplies that kept the Allies going and prevented them from running out of resources.
5) Helped shift alignment: The AEF helped the Allies shift the alignment of the war, as it arrived at an important time when the Germans were about to launch a massive offensive against the Allies. The US troops helped push the Germans back and prevent their victory in the war.
