Undersea Warrior, originally published in 1956 as Frogman, chronicles the wartime and post-war adventures of decorated British Commander Lionel Kenneth Crabb, a pioneer in early scuba technology. He utilized this equipment to locate and remove enemy mines, rescue trapped submariners, and perform other critical wartime activities. Author Marshall Pugh collaborated closely with Crabb to create this fast-paced narrative, highlighting the exploits of a revered English national hero. From their base in Gibraltar, Crabb led The Under Water Working Party, facing off against Italian Navy frogmen tasked with destroying Allied shipping using underwater mines. Crabb's mission involved the perilous removal of these mines, a task fraught with danger. After the war, he participated in rescue attempts for trapped seamen aboard the H.M. Submarines Truculent and Affray. Tragically, during a secret mission in Portsmouth, Crabb vanished under mysterious circumstances while diving near a Soviet warship, a topic briefly explored in the book. His fate remains uncertain, with theories ranging from being shot by the Soviets to capture and defection. A likely cause of his death was equipment failure combined with his declining health at the time. The book includes nine pages of illustrations.
