Marie is trapped in a farmhouse by a tank, but must call in her own coordinates to a circling bomber to bomb an underground artillery gun. She reflects on how her grandfather had to call in a strike, and used smoke signals. And how her father had to call in a strike using a mirror heliograph. Finally she calls in the bombing, plays dead, then circles and kills the tank - and its burning smoke marks the target, which she barely escapes. For bravery, the Resistance gives her a "medal", all they could find, a single red rose.
A Nazi sub steers for Shipwreck Rock to meet a supply ship: they're out of everything. While a USN frogman steers a tiny sailboat to Shipwreck Rock to meet a destroyer.

He swims under a shark and blows the sub - and survives to be rescued by a PBY plane.
