The USS Rasher had an extraordinary record in World War II: she sank 18 enemy ships and destroyed 99,901 tons—the second highest tonnage of the war. Her fifth war patrol is the stuff of legends. In August 1944 during a single night surface attack on a Japanese convoy off the Philippines, she sank the escort carrier Taiyo and three marus, and later during that same patrol she sank another ship. Reading more like a novel than an operational history, this book covers all aspects of the Rasher's combat history in a way that both the general reader and veteran submariner will appreciate. Author Peter Sasgen is the son of a Rasher crew member, and from his father's perspective he follows the sub from the builder's way through eight action—packed patrols to war's end. His richly detailed descriptions of submarine operations include lively commentary by former shipmates and excerpts from patrol reports along with a close examination of patrol procedures, communications, life guarding, and other topics rarely covered in such detail. Sasgen also explores the essence of submarine combat—aggressive leadership—and its role in the Rasher's success.
