In 2001, while vacationing on Panama’s Pacific coast, maritime archaeologist James P. Delgado came upon the hulk of a mysterious iron vessel, revealed by the ebbing tides in a small cove at Isla San Telmo. Local inquiries proved inconclusive: the wreck was described as everything from a sunken Japanese "suicide" submarine from World War II to a poison-laden "craft of death" that was responsible for the ruin of the pearl beds, decades before. His professional interest fully aroused, Delgado would go on to learn that the wreck was the remains of one of the first successful deep-diving submersibles, built in 1864 by Julius H. Kroehl, an innovator and entrepreneur who initially sought to develop his invention for military use during the Civil War. The craft’s completion coming too late for that conflict, Kroehl subsequently convinced investors that it could be used to harvest pearls from the Pacific beds off Panama, in waters too deep for native pearl divers to reach. In Misadventures of a Civil War Submarine, Delgado chronicles the confluence of technological advancement, entrepreneurial aspiration, American capitalist ambition, and ignorance of the physiological effects of deep diving. As he details the layers of knowledge uncovered by his work both in archival sources and in the field excavation of Kroehl’s ill-fated vessel, Delgado weaves the tangled threads of history into a compelling narrative. This finely crafted saga will fascinate and inform professional archaeologists and researchers, naval historians, students and aficionados of maritime exploration, and interested general readers.

In the pre-dawn darkness of December 7, 1941, five Imperial Japanese Navy submarines surfaced off the coast of Oahu. Secured to the decks of these vessels were secret weapons to be deployed for the first time in modern warfare: two-man midget submarines, intended to enter Pearl Harbor without being detected and torpedo the US Navy battleships lying at anchor there. None of them would return from their mission. “One of the last remaining and persistent mysteries of the Pearl Harbor attack is that of the Japanese Midget Submarines. It is a fascinating story of innovation, courage, secrets, and failed expectations. And it is not only a story of the morning hours of December 7, but of the years before to develop these weapons and the years after, where they were deployed in the great Pacific War and how they fared as weapons of war.” These words by Daniel J. Basta, from the foreword of this work, capture both the essence and the impact of The Lost Submarines of Pearl Harbor. James P. Delgado and his coauthors have worked on the story of these incredible craft for decades. They combed the records of the US Navy and the recollections of its veterans as well as Japanese, Australian, and British archives in order to uncover the truth. They have logged hours of direct observation and research on the midget subs in their final resting places, in some cases more than 1,000 feet below the surface of the Pacific. And in the end, they have woven a tapestry of scholarship, historical sleuthing, scientific insight, and good storytelling that will enthrall specialists and history enthusiasts alike.
