  49 **
  50 **      You get your supplies replenished and your captives are
  51 **      disembarked.  Note that your score is updated now, not when
  52 **      you actually take the captives.

  54 **      Any repairs that need to be done are rescheduled to take
  55 **      place sooner.  This provides for the faster repairs when you
