This is Diomedes. Diomedes is number 1401. Rio Grande is 0501. Old Man Bewcock commanded the 5th fleet. Badass Ralph Carlsen commanded the 14th fleet from the Diomedes. Both died when their ships were destroyed. Re-watch Battle of Mar-Adetta.
Actually the commanding officier die in battle while convering teh rest of the fleet retreat. He did tought once in a earlier battle to suicide but his second in command convince him to not. The fall of the Rio Grande is epic : P.
