The Lost Batallion
Plot Outline: Fact-based war drama about an American battalion of over 500 men which gets trapped behind enemy lines in the Argonne Forest in October 1918 France during the closing weeks of World War I.
It's up there with Gallipoli and Paths of Glory, but it lacks the usual message of the futility of The Great War most WWI movies have. At least so far. It's recommended.
