I’m really impressed by the masterful defense being orchestrated by Field Marshal Kleist. He’s been doing a great job ever since he got sacked at the end of March.
The news still hasn’t been released by the Germans. If the Soviets know, and I suspect they do, they are being tight-lipped about it. I’m guessing the Allies know from Enigma decrypts but are also not telling anyone to maintain the Ultra Secret.
The U.S. was taking some risks with their Japanese codebreaking, although it wasn’t a secret on a scale with Ultra. They are directing submarines to convoys the locations of which were detected by the codebreakers. The Take-Ichi convoy now en route to New Guinea is being tracked that way. In the aftermath of Take-Ichi the Japanese will convene a commission that will conclude of course their code is unbreakable, so spies must have tipped off the Americans.
