January, 1942: The Invaders are flying back to America across the Atlantic in Namor's aircraft when they spot an American freighter carrying war materials getting attacked by a U-Boat. They dive down to help, saving the freighter, sinking the U-Boat, and capturing its commander and the secret coded orders he's carrying. Back in Washington, the decoded message reveals that the Nazis plan to assassinate Churchill on his way back from his visit to the US and Canada. The nazi agent to carry out the attack is the Atlantean U-Man. Namor becomes enraged upon discovering that one of his people had joined with the Nazis and insists on fighting U-Man alone. Only Bucky sides with Namor on that plan, leading to a violent clash among the Invaders over how to approach the mission, ending with Namor and Bucky taking off with the Atlantean aircraft and leaving the rest to figure out another way to catch up before the Prime Minister is intercepted.
