This 1973 Time magazine profile of the returning American POWs recounts their creative resistance to pressure by their North Vietnamese captors for military information.
This nugget from James Stockdale, who would later stand as Ross Perot's running mate, is memorable stuff:
Navy Captain James Stockdale never broke. Asked for information about U.S. ships, he drew a picture of an aircraft carrier with a swimming pool and 300-ft. keel.
Oddly, the same story is also featured in John McCain's 1999 war memoir, Faith of My Fathers, (page 222), not as Stockdale's story, but as McCain's own:
Once I was instructed to draw a diagram of an aircraft carrier. I decided to comply with the order, but took considerable artistic license in the process. I drew a picture of the ship's deck with a large swimming pool on the fantail, the captain's quarters in a chain locker, and various other imagined details.... My fantastic rendering of an American carrier didn't arouse my gullible interrogator's suspicions until I noted its keel was three hundred feet deep.
