Okay, here are the raw results of the rolls:

14,700 Bohaddon

Bonuses: Disciplined Army (-5% casualties +5% to defenders)

8,000 Lizards

Bonuses: Defending Hightower ruins (+10% Bohaddon's casualties)

---------------------

Bohaddon Rolls

Combat Roll = 1 = 10% Casulaties

Significant Event/Disaster Roll = 2 (Loss of Flank) = 10% Casulaties

Scaling Hightower Ruins = 10% Casulaties

Army Size Difference -10% Casulaties

-5% Disciplined army

= 15% Total Casulaties

2205 dead.

------------------------

Blackfang Rolls

Combat Roll = 3 = 20%

Significant Event/Disaster Roll = 2 (Loss of Flank) = 10% Casulaties

+5% (Attacked by disciplined army)

Size difference + 10% Casulaties

= 45% Total Casulaties

3,600 dead.

-----------------------------------------

15% vs 45% = 30% Casualty Difference = Bohaddon Victory

Outcome: 4,300 remaining Lizards withdraw from Hightower's ruins, but in an orderly manner. Hightower region remains under Blackfang control, but Hightower Citadel lost to invaders.

-----------------------------------------

Basically you scored a pretty solid victory - not a crushing victory however, and so the Lizards did not rout. They have withdrawn to regroup, but the Citadel is yours, and would make for an apt staging post for further military action. Be warned though, that in light of this defeat, the Blackfang Empire may divert resources to your front (as would be logical).

EDIT: *DISCLAIMER* There is a chance that your general can die in my dice rolling system (which is how I keep losing my main characters!) so do be warned. If it happens, you have to accept it.
