If you want the armies to stay in formation as in not attack each other you can either freeze all you units or you can place them far enough apart so that they aren't in LOS of each other.
You tell the player by using the show instruction effect to go out and meet the english. send out the english through tasking. Then you can have a preset dialouge made with display instructions effects.
Just make a trigger that says after this happens delete all knights, then after a certain time bring them back in. Remember if you have your knights all disapear from wallace going to a certain area to disable the trigger and enable the show up trigger.
To see both ummm... hang on a sec...What you have to do is give player one spies but I don't know if celts get spies.
To make player one have to destroy english army make destroy object and select player two as target player then choose all military units
Hope this helps.
