Fox Hunt won't end? Please Help!

[Drahadis]

It says to direct a counter attack and eliminate the remnants of the german division. I've tried everything, I've sent lots of units to that spot the binoculars tell me to go after killing everything, I've let them destroy ALL my german tanks that I stole thinking that might do it... but nothing works!

Is there a cheat or a dev code I can use to force the game to win the mission?

BTW, this is the last US mission.
