Well here is what i had in mind when exposing the problem:

Army A is what i called the blocking one
Army B is what i called the blocked one.

Army A is on land A and don't want the army B, which is on land B, to reach the land C (where the capital of A is for instance)

So army A attack territory B and block the army B preventing him to go on C.

Now with your exemple:
Army 1 is in Province (A). Army 2 is in Province (B).
Army 1 has orders to move to (B).
Army 2 has orders to move to (A).


Army1 is supposed smaller so will reach arm2 faster:
there is a fight and the scout or whatever was in army1 die.

Now instead of being blocked (randomly it seems) the army2 will then move on land A.

@Soyweiser: i m totally lost with what you are saying. Arent you describing the rout mechanic ? or any mechanics that occur in fight ?
