Moffitt and Hitch (dressed as Germans) find Bertaine's daughter Marianne, a suspected collaborator, singing at the German Officer's Club. After telling her of her father's death, they drive her home and inform her who they really are. They also tell her they must use the local fishing fleet to accomplish their mission. Meanwhile, Troy secretly meets with American POW liaison officer Major Indrus. Troy then joins Moffitt at the house of El Gamil. Informed of the plan, El Gamil dispatches his men to the various harbor areas to alert the fishermen. El Gamil and the Rat Patrol raid a German warehouse to regain their captured munitions to aid the escape, but the Germans catch and execute El Gamil. Troy sets the action to begin at dawn to evacuate 5,000 Allied POWS. 

Gustav Luden, a German radio operator who wants to defect, sends secret information on supply shipments to the Americans on a frequency that the Rat Patrol listens to. The Patrol goes in after him. They get inside the German base and, once there, find that the Gestapo have seized Luden for questioning.
