I am plannning a WWI diorama and need to build the side of the trench. In your opinion were the sides lined with boards and support poles or wicker or sandbags. I plan to put a couple of layers of sandbags at the top of the trench. I know the depth varied a lot but I plan to make it slightly deeper than the heighth of a standing man. How many rows of barbed wire would protect hte trench, 2 or 3 or more. I would appreciate your feedback.
Thanks!
