Why Commander Samuel Dealey charged Japanese destroyers head-on during WW2 — and sank 5 warships in 4 days. This World War 2 story reveals how one submarine captain's aggressive "down the throat" tactic revolutionized naval warfare. June 6, 1944. Commander Samuel Dealey, captain of USS Harder, spotted three Japanese destroyers hunting his submarine off Tawi Tawi. Standard doctrine said run deep and hide. Dealey ordered flank speed — straight at the destroyers. Every training manual said this was suicide. Submarine commanders throughout the Pacific called it reckless. They were all wrong. What Dealey discovered that morning wasn't about firepower. It was about psychology in a way that contradicted everything the Navy taught. Japanese destroyer captains expected submarines to run. When Harder charged instead, they hesitated. By the end of June 9 — after sinking four destroyers in four days — other submarine commanders started doing what Dealey had done. And they survived. This technique spread unofficially through the Pacific submarine force, commander to commander, saving hundreds of lives before appearing in any training manual. The principles discovered off Tawi Tawi in June 1944 continue to influence submarine tactics today. 🔔 Subscribe for more untold WW2 stories: https://www.youtube.com/@WWII-Records 👍 Like this video if you learned something new 💬 Comment below: What other WW2 tactics should we cover? #worldwar2 #ww2history #ww2 #wwii #ww2records
