FULL FATHOM FIVE: U.S. submarines - S1.E21

In this episode of Victory at Sea, we see how the U.S. Navy's submarines contributed to the Japanese empire's downfall, sinking thousands of tons of ships, and strangling the Japanese. We see footage of ship upon ship from the House of the Rising Sun destroyed. But a price is paid for those whom the U.S. Navy classifies as "did not return".
