The Lazurian troops are in despair over the death of Forsythe and that Greyfield has ordered the execution of the remaining Lazurian soldiers. Brenner will not accept this and decides to help them escape. Greyfield and the rest of the New Rubinelle Army notice and order Brenner to attack the Lazurians, an order that Brenner refuses. Greyfield then states that what Brenner has done is treason and that everyone in the 12th Battalion is now marked for death.
