Jon and Stephen Atherton made this back in the 1970s. It was set in our backyard, and used the props we had- German uniforms, weapons and plenty of space. Jon starts out as the silent German soldier. In scene 2, Stephen, a GI, gets revenge with his trusty blade. In the third scene our family friend, Patrick Saint (son of our parents' good friend Prof Eric Saint, then Dean Medicine) takes revenge for the Motherland. Complicated plot!
