Tales to Astonish #98

Namor returns to Atlantis only to find it under attack by the Plunderer. As the two parties clash, an American sub overhead senses the vibrations and begins to drop depth charges in case it is the Sub-Mariner intent on attacking them. The charges not only take out the Plunderer's sub but also destroy much of the city of Atlantis. Plunderer escapes in his pocket sub. As Namor lies unconscious from the blast, the army of Atlantis heads for the surface, intent on all-out war with the world above.
