Don Winslow of the Navy #68

When a surprise attack on Suaki upsets the natives, Don Winslow and Red Pennington devise a daring plan to break away monkeys from the harbor and reach safety among the pilings. After Red is wounded and sinks beneath the surface, Don investigates underwater and discovers a native diver armed with a knife; the two engage in combat on the reef before Don escapes with a giant shell. As explosions rock a nearby guard tower and Don and Red flee the prison camp, Commander Winslow arrives with Lieutenant Pennington to mount a rescue operation, leading his men to secure the arsenal and prepare to engage Santos and his forces.
