Commander Battle and the Atomic Sub #5 (1955)

In a tale spanning centuries of undersea warfare, a dramatic flashback reveals the evolution of submarine technology—from early, doomed experiments to the mighty U-boats of World War II—before shifting to a modern-day mission where Commander Battle and Champ Ruggles face a terrifying fall from the sky, only to survive a miraculous recovery due to the vacuum of the upper atmosphere. As they land in a remote jungle, they must evade capture while infiltrating a hidden enemy stronghold, where a sinister plot threatens to plunge the world into war.

In a high-stakes rescue mission, Bill Battle and his team infiltrate a heavily guarded villa to free Jonnie Flint, using stealth, telepathic communication, and sheer strength to break him out through barred windows. As they flee through the night, pursued by enemy forces and dogs, they narrowly escape into the woods—only to face a new crisis when Jonnie reveals a hidden Arctic base could be launching a surprise attack.
