The submarine's commander gave the Robin Moor half an hour to abandon ship. The passengers were roused. Three more boats were lowered. As the sun rose, after the boats were in the water, the submarine fired a torpedo into the Robin Moor amidships, shelled her for 23 minutes. She went wearily down by the stern.
The submarine circled about the captain's boat. A Nazi sailor gave the men four tins of ersatz bread, two tins of butter. Said the Nazi commander: "I'm sorry, but you were carrying supplies to my country's enemy." The German promised to radio the Robin Moor's position. Then he slid away into the sea.
