American/ Turning Point mission

[aragorn666]

I've killed all german units and destroyed every single tank/mortar/whatever... I completed the primary objective an destroyed the enemy mortars, but the other primary objective with the counterattack is still open. After 15 minutes of searchin i found 3 infantry units in the south-east corner of the map, killed 'em but the mission still doesn't end. Don't know, what to do
