The Allies, including the Americans, attacked on the Meuse-Argonne in France on Sept. 26, 1918, and fought on there till the end of the war.
One of the most famous incidents of the battle was the losing of the Lost Battalion (not a battalion and not lost, as Clive Harris, Battle Honours guide, likes to shout).
Here’s a good link about that aspect of the battle.

And here’s the memorial:
(OK, this is a serious story of perseverance, etc., but isn’t it amusing that there’s a memorial to the Lost Battalion marked with an arrow?)
Here is the monument to honor the American capture of the high ground at Montfaucon, about six miles from the Meuse-Argonne American Cemetery. The monument has 264 steps up to a 360-degree observation platform.
The memorial towers over the ruins of the church — all that is left of the village.
