The former captain of the U.S. Navy submarine that collided with a Japanese fisheries training boat off Hawaii two years ago, killing nine Japanese, has said the book he recently published about the accident is intended to describe what he endured.

Scott Waddle, former captain of the 6,080-ton nuclear-powered attack sub USS Greeneville, was stripped of his command following the Feb. 9, 2001, collision that sank the 499-ton Ehime Maru during a rapid-surfacing maneuver being carried out as a demonstration for civilian guests.

Last week, Waddle, 43, released a book about the collision and its aftermath, "The Right Thing," from Integrity Publishing Inc., a Tennessee publisher of Christian books.
