Once the unit being pursued has completed its move, the pursuing unit is moved. If the pursuing unit makes contact with the pursued unit, it has caught its enemy and halts:
If the enemy unit is fleeing, it is hacked to pieces and immediately removed from play, exactly as if it had been run down by a charging unit. The pursuing unit may then attempt to reform.
If the enemy unit Fell Back in Good Order, the units become engaged in combat once more, becoming locked in place until the next player's turn when the combat will continue. During the next turn, the pursuing unit counts as having charged.
