Sub-Mariner Comics #1

Hitler decides to smash Atlantis and in the first U-boat attack, the emperor is incapacitated and Namor assumes command. The people of Atlantis fight back in \"Trojan\" whales and sharks that circle the Nazi subs without being noticed until their guns open up. The Nazi fleet is destroyed when Namor's people man gun emplacements on top of icebergs and rain down fiery death. Namor is captured by the lead sub, but he destroys the sub with his bare hands. He returns to his people who have finished rebuilding from the initial attack and ponders what to do next.
