The author examines Allied responses to the submarine menace in the recent war, detailing the creation and training of an anti-submarine force, the organization of fleets and shore bases, and the recruitment and instruction of large personnel complements. He surveys technical developments such as hydrophones, depth charges, nets, fast boats, decoy or mystery ships, and aircraft, and explains their tactical employment and supporting inventions. Chapters mix operational description with practical accounts of base administration, training establishments, and routine incidents at sea, emphasizing the methods, devices, and procedures that made effective countermeasures possible rather than focusing on singular heroic episodes.
