How to mod the killing/trampling rate of cavalry when chasing down routed units

Hi, I am currently playing a mod where if I send a cavalry chasing a routed unit, even when the cavalry trample a lot of the routers, they get knocked but not killed. So there is the odd sight of routed units going "oo" and "ah" while the cavalry rides through them, they fall down like mowed grass, but in the wake of the cavalry's riding past, they get up again. This is different from vanilla where cavalry could just ride through routers and routers would die merely upon making contact with a horse.

It makes the battles very long and drawn out. A cavalry unit takes several minutes to reduce a routed (!) slinger unit from 100 to 5 men. I'd like to lower the stats of routed units.

So I was wondering what part of export_desc_unit.txt this was in, if it's in that file. Like which stats need to be tweaked, is it the morale stat of routed units, or is it the chance-of-hit-per-strike stat of the cavalry.

Moved from the Scriptorium - please ask questions in the Modding Questions section.

sorry about posting in the wrong section.
Would someone know the answer to my question?
