Overrun and Lone Leaders

[Hugmenot]

I have never used the Overrun optional rule but from my reading of it:

1) in my opinion, it is a valid overrun and you would conduct an Assault in the overrun hex.
2) If the lone enemy leader survives the assault, you would attempt to remove it via 6.71
3) true if valid overrun.
4) true if valid overrun.
