How is the command of the Mauryan relief army handled as it enters the map in column from a single hex? (It's unlike the typical reinforcement entry and I can't find another scenario in the GBOH games I own to compare with it.)
Can the Nayakas enter their contingents in column using a wing command or individual order before the wing commander enters the map?
How is the movement allowance of the reinforcements affected (by turn or orders phase) as the various contingents arrive?
It`s maybe too late to provide the answer to OP. Nevertheless, Alan Ray answer is given in the link above. The idea is to use rules from TAKSHASHILA scenario - which means that +1MP for every unit after the first one will make congestion occuring on the map...
