Move Pursuers

Unlike fleeing troops, pursuers keep some order -- if the pursuit move would take them into (or through) a friendly unit or impassable terrain, they automatically stop 1" short instead.

If the pursuit move would bring the pursuers into contact with an enemy unit, they must charge it -- following the normal Movement phase charge rules, except no charge range roll is needed (the pursuit roll already proves they have the momentum). The charging unit still wheels and closes the door to maximise contact as usual. The charged unit is taken entirely by surprise -- it gets no charge reaction and must Hold.

If that enemy was already fighting an unresolved combat this turn, the pursuing unit gets to fight a second round of close combat immediately -- and if it wins that too, it can't overrun, automatically restraining pursuit (and may still reform). If the enemy wasn't already engaged, or its combat has already been resolved this phase, the new combat isn't fought until the following turn's Close Combat phase -- where the pursuers still count as having charged, giving both sides any charging bonuses that apply and the usual +1 combat result each, which cancels out.

Even a fleeing charged unit gets no charge reaction -- move the pursuers into contact with it exactly as when completing a charge against a fleeing enemy. If that unit is wiped out entirely, the pursuers get one final reform.

A unit that charged into combat and wiped out every enemy it fought can choose to move 2D6" straight forward instead of a normal pursuit -- an overrun, representing the unit surging on to find more of the enemy. This is otherwise a special pursuit move, subject to the same rules for intervening units and terrain. If the charged enemy was wiped out before the Close Combat phase even began (by a spell or template, for instance), the unit can still choose to Overrun or Reform from Victory at the start of the phase, unless it's already made some other move this turn outside the Movement phase.

A pursuing unit that reaches the battlefield edge moves off it entirely -- but unlike troops fleeing the table, it returns the following Movement phase using the Reinforcements rules, placed back as close as possible to where it left, in the same formation, facing back onto the field with its rear rank touching the edge. Leaving a model (a standard bearer is ideal) behind to mark the spot is a good idea.
