General Mireau walks through the trenches and checks on his soldiers' will to defeat the enemy. He comes across a soldier that is shellshocked and instructs the sergeant to remove that soldier, as he feels his cowardice can be detrimental to the group.
This clip discusses the origins and evolution of trench warfare and its use in several prominent wars, such as the American Civil War, and World War I. It also explains how the typical trench system was designed during World War I and how the modern day trenchcoat was inspired by a coat made for soldiers in the trenches.
