1. This is basically the one case were a lighter mounted troop gets a quick kill against something perceived as heavier. Almost all (Wb excepted) the other quick kills in the game come from heavy troops (like Kn) quick killing foot. This like Ps quick killing El is sort of an exception to the pattern.
2. Lh can get lucky and kill the Kn. Consider the difference in facing Kn with Cv or Lh. The Cv basically can't get lucky in a straight up fight and kill the Kn (please don't inundate me with your anecdotes but basically this is right, 10 Cv(O) v 10 Kn(O) (even Irr Kn(O)) basically will always end in tears for the Cv. Assuming of course a straight up fight, no flanks, maneuver, etc. Lh generally will die faster but have a much better chance of getting lucky and winning the fight. So if you are in a dominant position and have a choice you would prefer to grind down other troops with Kn than take on the relatively risky to fight Lh.
In any case here are the actual probabilities: Note: I don't list the
probabilites for Lh(F) as they are not as
straight-forward to calculate - but are never better off than Lh(O)
If you are Kn(O) or Kn(F):
| When facing ... | Lh(O) | Lh(S) | Lh(I) |
| with Kn(O) | Lh is killed 9 times in 36 | Lh is killed 4 times in 36 | Lh is killed 15 times in 36 |
| (or Kn(F) | Lh is recoiled 17 times in 36 | Lh is recoiled 17 times in 36 | Lh is recoiled 15 times in 36 |
| Combat is a draw 4 times in 36 | Combat is a draw 9 times in 36 | ||
| Kn is killed 6 times in 36 | Kn is killed 6 times in 36 | Kn is killed 6 times in 36 | |
| with Kn(S) | Lh is killed 9 times in 36 | Lh is killed 4 times in 36 | Lh is killed 15 times in 36 |
| Lh is recoiled 17 times in 36 | Lh is recoiled 17 times in 36 | Lh is recoiled 15 times in 36 | |

| Lh is recoiled 17 times in 36 | Lh is recoiled 17 times in 36 | Lh is recoiled 11 times in 36 | |
