Hector Boyes returned as naval attaché in Oslo and helped establish the channel that produced the Oslo Report on German weapons. The German invasion of Denmark closed the neutral route intended to keep that intelligence flowing. He later served in Tokyo and obtained useful information from Japan. His subsequent work in the Americas is described more cautiously: he was repeatedly near pro-German movements when they encountered problems, without evidence that he personally caused them. Diplomatic contacts, discretion, and regional familiarity made this retired officer useful far from a fleet command.
