This is actually a tricky one because the two interpretations people have put forward are both of similar validity. Some would point to the fact that the re roll replaces whatever result was rolled and draw from it that this would allow further orders to be given. Others would point to the fact that a failed roll means that the Brigadiers should stop and the re roll is the General intervening. If you like The Brigadiers messenger is shot down and the General and his staff intervene to allow the required movement to take place.
Both interpretations can argue validity because the rules do not have that vital final clarification; If the re roll is successful it only applies to that order OR if the re roll is successful, then the Brigadier can continue issuing orders.
For clarity’s sake, I started this debate thinking no further rolls should occur. I now am moving to the opposite opinion. This is because the reroll can take place for successful as well as failed orders. This fact only makes sense if new order fully replaces the old order and that further orders can then be issued by the Brigadier.
However it would be very useful if an answer from the rule writer or Warlord games could clarify this.
