Submarine Attack #18
U-boat captains under fire from Allied destroyers coordinate their attack on a sailing vessel. Captain Steve Hulas receives a barbershop whistle signal from a gull and later encounters two destroyers approaching their position. The crew survives the initial assault, and after regrouping in Boston Harbor, the captain meets with an admiral to commission more patrol vessels. In a subsequent mission 400 miles northeast of Rabaul, the submarine crew detects a Japanese Zero fighter and engages in combat on the surface. The final sequence reveals that one of the U-boat crew members is actually a German spy named Hans Hunscheon, a Nazi operative who had previously met with an American in Washington at the German embassy, prompting concerns about espionage within the vessel.
