Fortifying, the digging or occupying of a trench for defensive purposes, is a strategy that goes back to before the Romans. Simple fortifications took the form of shallow foxholes, while more elaborate ones involved networked trenches and tunnels with lines of communication and supplies. During the first American Civil War the Union fortified around Confederate citadels in order to employ siege techniques similar to those of the 17th and 18th centuries.
