Bases are taken by taking out all generals and base captains in a given area, and stationing one of the player's generals there.
Neither options are available unless players take over the bases in a line from their main camp to their opponent's. Victory conditions for winning a battle are to either to kill the commander or take the enemy main camp. Bases are groups on the map that appear red (enemies), blue (allies), or gray (neutral) and effect the dynamics of the map. In Samurai Warriors 2: Empires, the main concern of the battlefield is not generals but rather bases.
