As opposed to the phalanx
formations in the previous section, which largely rely on
attrition to win, flanking attacks are the very definition
warfare. The flanks of a battle line are the units on
either end. They have less support, and are therefore more
vulnerable than units in the middle of the line. The idea
behind a flanking attack is to hit your opponent's weak
spot, instead of going head-to-head, strength against strength.
There are a number of ways to execute a flank attack, most
if not all require your army to be mobile or at least have
some mobile elements. If your army consists of nothing but
slow moving units, flank attacks may not be your thing.
Let's have a look at some various flanking tactics, some
of which have historical precedence.
