How is redeployment/fortification accomplished?
Once a player has finished with all his attacks (if any) for the turn, he can “redeploy” (known as “fortification” in some sets of rules). This means moving any number of armies from one of a pair of neighbouring territories to the other (as usual you cannot leave a territory unoccupied). This is all the movement of armies that is ever allowed in the game except upon winning a battle. The old U.K. rules impose a maximum of 7 to be moved. This set of rules also denies reinforcement armies if you attack. Together, these rules mean that a buffer zone of 1-unit territories controlled by your opponent can be quite a useful defence. (Hence there is some reason to drive an opponent’s territory down to a single unit without actually taking it.) Some people remove the limit of 7 (as in the U.S. and new U.K. rules). What is probably a house rule, however, is to allow the movement of the group (perhaps limited to 7) through an unlimited number of connected, controlled territories. Another variant
