One of the reasons the casualties were so low in the Battle of Ostwald was quite simply the "god awful die rolls". In one series of melees there were 3 Battalions of 7 elements on each side, both sides throw the die requiring a 6 to cause a "hit", out of 21 die per side both got 1x 6. So in in the case of a draw both sides withdraw in disorder. Yet when they go back in again the result is the same, statistically it shouldn't have happened, but according the die rollers lore it was bound to happen.
In fact this was the first game I have played where we had so many drawn melees, it was only with the Cavalry where the dies were better and inflicted decisive results (unfortunately for Rechburg).
Sometimes it seems there is no figuring the dice gods.
