The author of A Night to Remember, Walter Lord, describes the sinking of the Titanic as surprising.
In the book, Lord vividly describes the events leading up to the sinking of the Titanic, including the warnings that were ignored, the inadequate number of lifeboats, and the chaos and confusion that ensued as the ship began to sink. Despite these factors, the passengers and crew were largely unaware of the impending disaster until it was too late, making the sinking a shocking and surprising event.
