For those that are interested, here are the historical circumstances surrounding those commanders that received the MoH during the war:

In short:
- John Phillip Cromwell: remained on board his submarine as it sank to its depth, rather than risk being captured and tortured by the Japanese and revealing military secrets.
- Samuel David Dealey: sank five destroyers in one engagement.
- Eugene Bennett Fluckey: sank several targets in shallow and heavily escorted waters while on a war patrol that lasted nearly 2 months.
- Howard Walter Gilmore: gave the famous order "Take her down" after being mortally wounded in a gunfight with an enemy gunboat, thus allowing the submarine to escape and make it back to port.
- Richard Hetherington O'Kane: sank several ships from two heavily escorted convoys while under a barrage of enemy gunfire while on the surface over the course of two days - not to mention the sub barely managed to avoid being rammed by a freighter.
- Lawson Peterson Ramage: similar conditions to O'Kane.
- George Levick Street III: sort of like both 5 and 6.
