Trigger to catch fleeing group members

[Harvey]

Hi

Another trigger question from me :-)

What I have is a convoy of 3 vehicles heading down a road. The player lays satchel charges in order to stop them. What I am finding is that if the satchel charges only catch 1 or 2 of the vehicles, the remaining vehicles turn round and head back along the road to their starting point. I guess they are fleeing. So I want to catch this and have the mission fail if not all the vehicles are destroyed. Possible solutions I have are :

1.Stop the vehicles fleeing so they can be destroyed by other means.

or

2. To have a trigger that detects that not all of them have been destroyed and to fail the mission off that.

However, I dont want the mission to fail if the vehicles are still around the area of the player, only when they flee down the road back to base.

I did a trigger that had the condition (count units groupname) <3 of type End #5 and linked it to the convoy group but this is firing straight away if some of the convoy survive the bombing (which I guess it would), but I cant work out how to have it only triggering when the convoy have fled back down the road.

It maybe easier to just stop them fleeing, but this isnt ideal...:-)

Any help please ? ! :-)
