I should know the answer to this but I will ask to get other input just to be sure.
I have a march order in one territory and there are two sets of units surrounding my one territory, can I march into one area to engage a combat situation and with the remaining force that I have split up, can that then be marched into the other adjacent area to engage a combat? So basically, two combats with one march order? So forces from A move into B to fight, but the remaining forces in A move into C and begin another fight?
Subsequently, I have done a similar move with the same march order but only one of those moves was combat, the second move was moving into an unoccupied territory containing a castle (without a garrison). Was this move okay? So forces from Z move into Y to fight, but the remaining forces in Z move to X uncontested (no fight ensues).
