Boyes, Graf Spee, and the Asama Maru affair

Was Hector Boyes involved in the Admiral Graf Spee affair?

No; he was in Tokyo, where he was more closely involved with the Asama Maru incident and other Japanese matters.

Hector Boyes was in Tokyo during the Admiral Graf Spee affair and therefore was not involved. His assignment instead connected him with the Asama Maru incident and other work in Japan. Those were contemporary intelligence and diplomatic episodes involving British naval interests, but they were separate events. The answer prevents Boyes's Japanese work from being folded into the Graf Spee story.
