Thanks! Bah, I should be putting better notes on my entry when I do work based on obscure and outdated historical stuff... It's just Harry and Snape in a trench in World War 1. They're holding feathers because in Britain at that time, people would give men a white feather as a sign that they thought them a coward for not enlisting in the army. Of course, the white feather *also* was seen as a sign of peace; being a pacifist...
