I just checked and it seems that ALL units were destined to exit. I guess that one can't just take the flags and push the americans out of the way and expect to score big. Both games I played ended up in bloody infantry confrontations but, especially the second time, I had pushed the americans to the SW edge of the map, securing the train station with a strong position. I thought that would make it. There are two choices here: either you push them out of the way quickly and leave a minimum force the control the flag while you send the rest of the troops out, or as wbs suggested, just hammer the americans into oblivion and hope for a surrender.
Thanks to you both for the tips.
Still new at this game but I LOVE it!
