I need to see more classic movies.
Paths_of_Glory(1957) is truly a classic WWI movie.
After the French general orders his troops to make a suicide attack on German positions completely outnumbered and outgunned some of the battalion survive to fall back to their trenches, so he orders his artillery to shell those same, his own troops .
When the artillery soldier says he cant shell their own french won troops without written orders he threatens to court Martial him too.
So the general presses to court martial and execute the surviving, his own troops, for cowardice.
