Because the army deliberately retires toward a prepared position, Keyes can restrain the navy's urge to answer the first crisis immediately. Holding the fleet at Ceylon until January could bring another battleship and possibly an aircraft carrier, with Formidable mentioned as a difficult but conceivable addition. A surviving Singapore base might persuade American and Commonwealth leaders that reinforcing the theatre also helps protect the Philippines and Australia. The scenario even uses that argument to ask MacArthur for spare brigades. Any such reinforcements remain contingent. Preserving the base still creates time and coalition leverage that a premature fleet sortie would surrender.

Hold the fleet and bargain for reinforcements
A controlled land withdrawal gives Keyes time to hold the Ceylon fleet until January and argue that defending Singapore also protects the Philippines and Australia.
