You are correct - there are none! (Keeping the rules simple and all that. )
I have included a Risk to General in the Napoleonic version - so you might wish to use the below:
Risk to General: Attached
generals are at risk in the heat of combat therefore an attached general must
roll 2D6 if:
a) Attached to lead unit and lost a charge combat with a Retire
or Whipped result or
b) Attached to unit and lost a melee.
2 = Your general, in a most craven fashion,
surrenders to the first man who will accept his sword. Your Brigade Falters!
3 - 9 = No effect.
10-12 = Your general is shot through by the opposing regiments crack shot! Your Brigade Falters!
