General, the situation is critical.  The Soviets have encircled 6 divisions at Korsun-Shevchenkovsky.  Hitler has refused to allow the trapped men to break out.  So, Manstein has gathered the bulk of his tank strength to save the two corps.  We must drive forward at once, before they are destroyed!

(If playing with rules do not buy any new units, except to replace any core losses.)
