What happened at Argonne forest?

Answer 1

What is still the biggest battle ever fought by American troops. The area was so unpromising for an attack that the French had not even tried there since 1915, and the barbed wire and pillboxes were all overgrown and covered up so they were impossible to see. The Germans had three or four complete trench systems, one behind another, so if an attacker managed to break through the first one, he still had to do it all over again, several times. The Germans were atop rugged hills, so the attackers had to fight their way uphill. The attack began September 26, 1918, and was still going on when the war ended seven weeks later. More than 80% of the one million American combat troops in France were involved. Eventually the Americans broke through all the German defenses and into open country, and were driving deep behind enemy lines when the Germans gave up.
