1942: On Guadalcanal, a machine gun section led by Marine Cpl. Anthony Casamento is hit so badly during the fourth (and final) battle at the Matanikau River that all but Casamento were grievously wounded or killed. Despite his own wounds (he was hit 14 times during the engagement), Casamento single-handedly held his position and repelled numerous enemy attacks. Casamento will be awarded the Medal of Honor in 1980 after surviving eyewitnesses to his actions are found.

1952: (Featured Image) The U.S. tests the world’s first hydrogen bomb, codenamed “Ivy Mike”, at Eniwetok Atoll.

The blast digs a mile-wide, 150-ft. crater and literally wipes the small island of Elugelab off the face of the Earth.
