Do the Allies need to merely disrupt an enemy nation's control by the Japanese, or reoccupy the required hexes for Allied control (ie. the Allied control of Davao, or both Davao and Manila in the Philippines)?
Just want to confirm but suspect both Davao and Manila.
A nation surrenders if the opposing player controls certain hexes of that nation during the National Status Segment. If Japan surrenders the game is over and the Allied player wins the game. If an Allied nation surrenders, the Japanese player automatically gains control of all of its on map airfields and ports that are not occupied by Allied units unless the specific rules for country’s surrender below specify otherwise. An Allied nation can only surrender once per game. Allies can retake surrendered country by recapturing the locations that the Japanese player had to capture to make the nation surrender. If they do, they regain control of all of that nation’s airfields and ports except for those that have a Japanese unit (of any type) in the hex. However, this does not cancel the card draw effect from surrender.
