There would have been no subwar in WWII, that easy. some subs would have been bombed out of the water in the first month when they started to yodel, the rest would have retuned to port early to ask what that recent yodel comm was meaning. Some skippers would have been executed for insubordination when mentioning that line saying "du dödel" (a nasty word in german), and generally many would have been brought to the Nürnberg tribunals for having yodeled at all, which is rated as a crime of inhumanity to ears in general and Allied sonar operators in special.
