NavAir, still patting themselves on the back for Philippine Sea, Sibuyan Sea, Lingayen Gulf, etc, wanted credit for post-action killing. Their claim has always been that they happened upon the damaged pair and sunk them.
Destroyers is a hard claim to make as DD skippers were brave, but not stupid. USS Laffey at Guadalcanal was in every DD skipper's memory. No one wanted a repeat of that. The DD's and PT's were to shoo the two battleships into the waiting guns of the USN battle line. And that's where the story blurs. The DD's apparently did just that. Just enough smoke and gun fire to convince the IJN that it was safest heading forward.
The PT's however, never apparently had a plan according to S.E. Morrison's "Two Ocean War." Ballantine's "Death Of The IJN" also states squadrons of PT's ("numbering in the hundreds") making willy-nilly attacks all in the name of "just because" and "because they are there."
Fuso's own logs put her at slight damage from torpedos. So she couldn't have tangled with a destroyer. Or two. PT torps were indeed air variants. Tho one or two squadrons may have had the older 21" jobs. Yamashiro's TROM reports "rocket fire" as well, which couldn't have been DD's.
As for Hood, several things come to in to play. Firstly, Holland and Leach were expecting the Germans to do what the British did. Two ships; one a battleship and one a cruiser? Why...of course the battleship is in front old man. And both ships having four turrets, one stack - well it's easy to see how Hood and POW imagined the ship in front to be Bismarck. So "Last Days Of The German Navy 1939 - 1945" accurately (as does every other account) has Eugen coming under fire first.
Lutjens was picked by Hitler as he was anal retentive and a stickler for detail. So Lutjens is making smoke (which is what a cruiser would do to protect her battleship) as he intends to break off. Lutjens isn't an idiot; he knows (1) that Hitler's orders are irrefutable and (2) he's up against two RN capital ships, one of which is 15" armed Hood. The RN continues hammering Eugen. How many salvoes would it take you (were you Eugen) to get the RN range?
By the time Lutjens changes his mind and joins the fight, Hood has already gotten her boat deck hit. Unless the German had some mutual support training where one ship could give coordinates and bearings to another, there's no way Bis' guns could have jumped ahead of Eugen's. IMHO of course...
Tedd Brigg's book clearly places Eugen's fire first, with Bismarck's as an echo. Which would make sense as smaller 8 inch guns reload faster than 15 inch guns. Now of course, the word "clearly" is Tedd's recollection which is as good as anyone elses that was there.
