First I just want to say I'm really enjoying the campaign and think it's really well done.
I'm having an issue with Mission 10 where you're on standby and have to help troops that have been ambushed. I've tried the mission about 8 times but only twice have I made it to the actual Valley where the first group of troops is located. Every other time the mission simply ends just before the turn to enter the valley. I think I'm doing something wrong because it's always after the statement from Peter about flying low and fast over the trees so the enemy doesn't hear us. However, I'm flying as low as I can over the trees (sometimes between them) and it still kicks me out.
Can you please tell me what I'm doing wrong? Is it because I'm flying along the south edge of the valley?
Thanks for your help and for the great campaign.
