The title could also be: "Good Men Are Dying For Nothing". This is about very bad leadership, ignorance, arrogance, inhumanity and stupidity of war. Mostly aristocratic, unexperienced commanding officer dilettantes "play war" and are quite comfortable to sacrifice their subordinates. This "horror" happened in 1854, but it can easily occur nowadays at any place, any time.
Not just a blistering satire on the folly of war but the hypocrisies of class, station and the underpinning institutions. It has a most unusual texture for the period and has suffered more than most under the editor's thumb. Seek out the longest version possible and marvel at the scaborous delights of the damning script and production.
