In fact, the complexity of the trenches was designed to counter another favored stereotype of the First World War -- that soldiers were seen as easily replaceable machine-gun fodder. The trenches were cut as zig-zags so that, should an enemy force breach the lines, all the troops weren't just standing in a straight headshot-able line from the North Sea to the Alps. Also, the walls were paneled with wood and the parapets reinforced with a ceaseless line of sandbags, and there were large medical stations installed throughout, because even these generals took care not to just let entire regiments die from gangrene and patience.That's just the beginning of the complexity of World War I trenches. They were sometimes even connected underground to larger staging areas. Read about them and four other parts of war that aren't exactly as Hollywood portrays them at Cracked.
