Preluded by the author's personal experiences aboard a converted passenger liner during its days as troop transport, by his discovery of one world on and under one deck, the new and significant contributions to American life made by the National Maritime Union -- this resolves into a history of that Union, the men behind it, its accomplishments. Definitely a pro chronicle, subject undoubtedly to challenge, to argument, to disagreement, this records much precise information on a topic of the times on which there has been much misinformation. From the soul of a ship to the soul of a movement, this fuses the line of development, in the author's terms, of brotherhood, common and, gigantic synchronization. He emphasizes the importance of the rank and file; he gives profiles of the prime movers, Joe Curran and others; he highlights the spiritual rehabilitation, the heroes the Union has harbored, the vitality of its internationalism. This has the fervor of a cause, the crusading of a convert.
