The Young Indiana Jones Chronicles S01E04 - Verdun, September 1916

Old Indiana Jones lectures a so-called 'Pirate of Wallstreet' sitting next to him on a plane about the horrors of the first world war. The man reminds old Indy of the generals who casually send hundreds of young men off to slaughter in the trenches with each battle. Indy himself had managed to get a position as a courier, while his friend Remy had ended up in hospital, only to be ordered back to the front as soon as his wounds have healed. On a reconnaissance mission, Indy learned the Germans were bringing in two Big Bertha's, enormous howitzers to be used at Verdun.
