You have seen the official orders; these must be read to your troops. For your eyes only, I add this warning.
The recall to the Imperial City will not be welcomed by the soldiers. The rumors of what we face there have spread faster than the wind. Fear grips all who have any sense. The brave overcome this fear and march.
You may face a mutiny. Give them no time to organize. Strike camp immediately. If you sense resistance, kill the ringleaders. Hesitation could mean your death and the loss of your troops for the Empire.
I march to the northwestern bridge. Meet me there. To delay means death.
