Scenario rules.
1) The battlefield is "broken ground". So all troops, with the exception of S, LI and T are disordered after moving on it and cannot move as groups.

2) With a roll of a double 1 by the Teutonuc player during initiative, the ice collapese. All troops on the lake it are destroyed and the game is over. (well more dramatic than reality but gives suspence when the Teutonic player roll for initiative )

Have fun!!
