The Battle is now over and all losing players discard all Coins they allocated on the War tile to the common pile.
The winning player, however, gives all Coins they allocated on their War tile to the losing players. The Coins are distributed equally among the losing players, who place them in their reserves to use in the following Battles. If the number of used Coins can’t be distributed equally, the winning player decides which player(s) should get an extra Coin.
War is then resolved in the next Province, until all Provinces with a War Number token have been resolved, and the War Phase comes to an end.
