The enemy sailors rush for their gun. What does the crew of the O'Bannon do?
Yes. There on the deck of the O'Bannon was stored a large number of potatoes. The crew grabbed them and started lobbing the spuds at the enemy sub. It was later speculated that the enemy sailors thought they were grenades but whatever the cause the sailors on the sub rushed about picking up the potatoes and tossing them into the sea. This gave the O'Bannon time to haul around and pound the sub with something more substantial than potatoes. The sub was later confirmed sunk.
When word got back to the Association of Potato Growers of Maine they cheerfully seen the O'Bannon a commemorate plaque.
