Submarine Attack #21

When Captain Tyne falls ill, the submarine Sea Wolf gets a new skipper—a desk officer named Captain Mace who the crew views as all spit-and-polish, no combat experience. But when an urgent order comes to stop a Nazi troop convoy from reaching French soil, Mace must prove whether caution and discipline can match the fearless reputation his predecessor built. The Sea Wolf engages one of the most heavily defended targets a submarine has ever attempted, with Mace leading from the front in a desperate gamble to change the course of the war.

The crew of the submarine Roamer pursues a damaged enemy U-boat across the North Atlantic, tracking it through treacherous waters toward its home base in the North Sea. Following their prey unseen through mine fields, they position themselves for a decisive strike at the very heart of enemy operations. What begins as a desperate chase becomes something far more consequential when the hunted becomes the hunter's unwitting guide.

The crew of the U.S.S. Crabfish turns to piracy on the high seas when Captain Mo Davis hatches a daring raid on a Japanese naval depot in French Indo-China—first looting a tanker for fuel, then staging a nighttime assault to steal torpedoes and ammunition while the enemy port burns. With Lt. Dave Cochran and his guerilla fighters leading the charge ashore, the submarine crew works frantically to load their prize before dawn, setting the stage for an even bolder strike against a Japanese ammunition dump on Sumatra that could cripple an entire division.
