My world's version of the war was different than others. But the vast majority of countries around the world were involved. Trenches had been dug separating the armies and making the land between uncross-able. I was with several companions to track down one of Germany's generals when a woman begged for help for her town behind the German trenches. So I crossed the battlefield.
History books can probably go into more details about World War I. When are you from?
