[Homer_J_Simpson]

HIGHLY RELIABLE INFORMATION HAS BEEN RECEIVED THAT CATEGORIC AND URGENT INSTRUCTIONS WERE SENT YESTERDAY TO JAPANESE DIPLOMATIC AND CONSULAR POSTS AT HONGKONG, SINGAPORE, BATAVIA, MANILA, WASHINGTON, AND LONDON TO DESTROY MOST OF THEIR CODES AND CIPHERS AT ONCE AND TO BURN ALL OTHER IMPORTANT CONFIDENTIAL AND SECRET DOCUMENTS.

But not Honolulu.

[CougarGA7]

Good point, but I would have to wonder what they had in Honolulu. Everything I’ve seen on messages sent from Honolulu is in the old J-19 code. They may not have even had a cipher for decoding Purple. They certainly would not have had anything for any of the JN-25 series.
