I'm hardly an expert but from that I've read I got the impression that by and large the UK's Royal Navy Admirals were a far slight better than their Army counterparts. The Army could afford to be a aristocratic playground because it was the navy that kept the country safe; whereas the army was mostly used for colonial expeditionary warfare.Daryl wrote:Don't forget that RFC is a Naval Historian, and his books take their cues from the interesting period between HMS Victory and Jutland and beyond.
I'm not totally sure about the RN's Admirals but know that the British Army's Generals were described as "Donkeys leading Lions". Family pedigree and connections were much more important than competence, so it is reasonable to assume that this applied to many in the RN as well. The RN just knew that they had the best ship technology, and this proved to be a problem at Jutland.
Now there are screw-ups in any service. And the some Admirals did seem to believe that hearts of oak could overcome surprising disadvantages in speed or firepower (See the court martial, though later acquittal, of Tourbridge for refusing to charge a battlecruiser with four older, and slower, armored cruisers). But buy and large their RN's sense of superiority didn't rise to the level of delusional or significantly impair their fighting capabilities.
Go back in time a while, and look at their [edit:Revolutionary War -> War of 1812] skirmishes with the USN's "super frigates". Yeah, a couple British frigates got beaten, which was humiliating, but their Admiralty quickly gave orders for frigates to avoid engaging their USN counterparts one-on-one. And not long after that the RN battle squadrons largely hard the USN blockaded into port. Some captain's hubris caused them to attack larger and more heavily armed ships, but the navy quickly slapped behavior down after they learned of the losses.
