Okay, okay - his name was Daniel Frazier. Nobody at the time was sure if it was Frazier or James who threw themselves in front of Decatur to protect him - it is known that James was certainly vocal about having done so, but both were wounded during the battle.
DD602, USS Frazier (Benson class), was named after him - earned 12 battle stars in the Pacific in WW2, and was credited with sinking 2 Japanese subs, one by ramming.
The problem with me isn't answering the question (although that's hard enough), so much as it is coming up with a new one afterwards. But here goes:
When the USS Panay was sunk by Japanese aircraft in December 1937, three gunboats from two different nations came to her aid - one of which was herself holed below the waterline by Jap artillery at the same time the Panay had been attacked.
What two nations were these ships from, and what were their names?
