Can the Royal Navy protect the shipping lanes of Britain’s far-flung empire long enough to turn the tide against the U-boats? Or will the Kreigsmarine and Supermarina cut England’s merchant marine lifeline? Will the French remain loyal to the Allies, or will they bring to life Churchill’s greatest nightmare and fight alongside the Germans? Can the Americans withstand the Japanese onslaught long enough to bring their mushrooming strength to bear? Or will Japan complete its conquests in the Pacific and force the Allies to negotiate for peace?
