Commander Battle and the Atomic Sub #7

Commander Battle and the Atomic Commandos receive messages from Berlin and Russia, learning that the enemy has discovered their atomic submarine. After being brought to an installation, they are told the Russians have prepared flying saucers containing H-bombs, and the Commandos are thrown into an escape-proof compound to prevent them from warning their country. Using an electronic teleradio device, young commando Jonnie Flint manages to contact his superiors on August 15th, and the team must escape the prison and climb to safety while fires rage around them, with the satrap threatening to hunt them down.
