Paris (JFK+50) On June 3, 1918, American and French forces met at the Marne River and forced the Germans back across the river. It was the first time American troops made a significant contribution in the First World War.
The action at Chateau-Thierry was brief and the French commander, according to legend, urged the American commander to retreat. He is said to have responded...
"Retreat hell, we just got here!"
The Battle of Belleau Wood, however, continued for three weeks. Ultimately, the Germans were forced to retreat.
