1942: Chief Machinist Mate Henry L. Thompson, 6th NCB, was the first Seabee killed in action. He died during a Japanese naval bombardment of Henderson Field on Guadalcanal. Thompson and five other Seabees were huddled in a deep dugout to avoid the huge 14-inch armor-piercing naval shells that the Japanese naval task force hurled into the Seabee camp area. One shell landed directly in the hole. The concussion collapsed the sides of the hole, burying the six men. Two Seabees, bravely disregarding their own safety, dug the six men out of the dirt-filled hole. Though the other five men survived, Thompson was found dead, sitting upright in the bottom of the dugout. It was believed that he died from the concussion as much as from suffocation. The two men who dug out the men, Shipfitter 1st Class H.L. Osborn and Shipfitter 1st Class D.L. Gillis, received the Silver Star for their actions.
