The United States Coast Guard in World War II

Thomas P. Ostrom's comprehensive examination of the United States Coast Guard during World War II fills a significant gap in military historiography. While the exploits of the Army, Navy, Marines, and Air Forces have been extensively documented, the Coast Guard's contributions have often been relegated to footnotes in broader narratives of the war. This work rectifies that oversight by presenting a detailed account of the service's multifaceted role in both domestic waters and overseas theaters of operation.

The book chronicles the Coast Guard's transformation from a peacetime organization focused primarily on maritime safety, law enforcement, and search and rescue operations into a vital component of America's wartime military apparatus. Ostrom documents how the service expanded dramatically during the war years, growing from approximately 10,000 personnel in 1940 to more than 170,000 by 1945. This rapid expansion required intensive training programs and the integration of thousands of reservists and temporary personnel into an organization that maintained its distinct identity even while operating under Navy command for the duration of the conflict.

One of the book's strengths lies in its balanced treatment of domestic and overseas operations. On the home front, the Coast Guard assumed responsibility for port security, beach patrols, and the protection of vital waterfront facilities against sabotage. The service established coastal picket patrols using small craft and even mounted horse patrols along remote stretches of coastline. These domestic security measures, while less glamorous than combat operations, proved essential to protecting the nation's maritime infrastructure and maintaining the flow of war materials.

Ostrom devotes considerable attention to the Coast Guard's combat roles, particularly in amphibious operations. Coast Guardsmen manned landing craft during virtually every major amphibious assault in both the European and Pacific theaters, from North Africa and Sicily to Normandy, Iwo Jima, and Okinawa. The service's expertise in small boat handling and navigation in challenging coastal conditions made Coast Guard personnel particularly valuable in these dangerous operations. The book documents the heavy casualties sustained by Coast Guard crews during beach landings, bringing to light stories of courage and sacrifice that have received insufficient recognition in popular accounts of the war.

The narrative also examines the Coast Guard's role in anti-submarine warfare. Coast Guard cutters conducted convoy escort duties in the Atlantic, protecting merchant vessels from German U-boats. Several cutters distinguished themselves in combat, with some credited with sinking enemy submarines. Ostrom provides detailed accounts of these engagements, drawing on official records and personal testimonies to reconstruct the tension and danger of antisubmarine operations in the Battle of the Atlantic.

Another important aspect covered in the work is the Coast Guard's responsibility for manning weather stations in harsh environments, including Greenland. These stations provided critical meteorological data that influenced strategic planning and tactical operations. The service also operated the Long Range Aid to Navigation (LORAN) system, which proved invaluable for both military and civilian navigation throughout the war.

The book addresses the Coast Guard's unique position within the American military structure. Transferred to Navy control during wartime, the service maintained its distinct organizational culture and traditions while integrating seamlessly into naval operations. Ostrom explores how this dual identity shaped the Coast Guard experience during the war and influenced its postwar development.

The author's research draws upon official records, unit histories, and personal accounts, providing a well-documented foundation for the narrative. The book succeeds in presenting technical and operational details in accessible language that will engage both specialist readers and general audiences interested in World War II history. While the chronological organization occasionally results in fragmented treatment of certain topics, this approach effectively conveys the simultaneous nature of the Coast Guard's diverse responsibilities.

This volume represents an important contribution to understanding the full scope of American military participation in World War II. By documenting the Coast Guard's extensive and varied contributions, Ostrom ensures that the service's role in achieving victory receives appropriate recognition. The book serves as both a valuable historical record and a tribute to the men and women who served in the Coast Guard during the nation's most challenging conflict. Readers seeking a complete understanding of America's World War II experience will find this work an essential addition to the literature on the subject.
