A real period piece, and predecessor to “The Russians are Coming!” In WW I Germany actually did manage to lay mines in a few spots along the east coast. Then, early in WW II, these fears were rekindled by James’s summary of incidents two decades earlier. An interesting summary of the earliest – and surprisingly effective – days of U boat incursions. Bound as issued in blue cloth with paper cover and spine labels. Pictorial dust jacket lightly chipped. Some helpful reader has left pencil notes on the front blank. Scarce. Only a single copy online as of April 2026.
