If, by some mad chance, you find yourself in need of basic instruction in trench layout and construction, this thin volume published just two months after the US declared war on Germany is just the thing. It illustrates all the steps from men frantically digging shallow pits under fire to fully developed systems of trenches, bunkers, and overlapping fields of fire.
