The Dorsal Mountains - the eastern extension of the Atlas Mountains of northern Algeria - dominate northern Tunisia as well. The Germans controlled the high ground where the Dorsals' Eastern and Western branches met, giving them an excellent observation point overlooking any Allied drive on Tunis. To prepare for the main effort scheduled for Christmas Day, the Allies needed to clear and seize the heights. The 7th Moroccan Tirailleur Regiment drew the honor of occupying Rebaa Oulad Yahia to provide the base of operations to tackle the heights themselves.

The Moroccans secured Rebaa Oulad Yahia as a base for further operations, but the push deeper into the hills bogged down due to tough Italian resistance. On the 22nd, Gen. Louis Koeltz, commanding the French XIX Corps called off the offensive without the heights having been secured. A stronger attempt a few days later also failed.

Revision of scenario 11 from the first edition. May be played with Moroccan counters from Swallows of Death instead of French counters from this game.
