Bogus &co rout after 1 casualty?

[von_Schmidt]

Here I was, all geared up for a massive battle, prepared to lose vast amounts of troops to the dreaded Bogus and his hit squad.

Battle starts, both sides buff up, the Dark Knight flies into my battle line and gets chopped up after trashing some cannon (sword?)- fodder.

Next thing I know, the Brave Fellowship of Heroes do a runner - without any of the survivors even coming close to contact with my troops.

If this is a result of the rule that commanders without troops flee the field after the first casualty, how come Bogus is so feared?

It's not as if my army contained any special troops; just cav, Sidhe inf, longbowmen.
