Camera pans over French soldiers in several trench locations along the Marne line during World War 1. Some are also seen digging new trenches next to a road. Several French troops and a farmer stand near two French Schneider tanks, one with a White diamond painted on its side. In far background troops are seen marching single-file. Scene switches to American Expeditionary Forces (AEF) moving single-file along a tree line. The film is destroyed between time code: 01:23 and 2:02, where it picks up again showing American soldiers gathered in a clearing in the woods. Horses and wagons, trucks, and a staff car are also seen. Next scene shows a long line of U.S. troops and trucks clogging a road. German prisoners, including some ambulatory wounded, walk past French canvas-covered wagons, and are seen near French soldiers. French troops with wagons pulled by donkeys, pass German prisoners of war, and enter the town of Longmont. Mounted French soldiers pull a caisson. The destroyed Abbey of Longmont is seen in the background as mounted French soldiers ride into the town. More German POWs walk towards the rear, past them. More views of the destroyed Abbey. A contingent of French troops with wagons and caissons advances toward the front.

A light cloud of gas passes over the soldiers and a larger cloud of gas is seen further away, in front of the trench. (World War I; World War 1; WWI; WW1)
