Pretty much coastal bombardment was considered an unnecessary risk for the bigger ships. Like the submarine/torpedo boat flottillas offensive blokade policy could have faired better such means could have been used properly as well in a counter-blockade task. Small coastal submarine/TB forces were admited to be sufficient, if provided in large numbers, to fool any attempt of invasion by sea or coastal bombardment missions. Again another quote from Mr. Fisher that shows a bit of the same context (sorry but been reading a lot on him lately and on submarine doctrine in WWIJWintjes wrote:Hmmm, I don't like this idea of the High Seas Fleet being merely a fleet-in-being. It was used that way for much of the war, but it could have been used differently - if you look at the planning behind Doggerbank you clearly see that the main idea behind bombarding coastal cities was trying to pull inferior forces out to the sea in order to ambush them with the van of the fleet. Now, this failed several times for various reasons, mainly because the HSF was not used aggressively enough. But imagine one successful engagement, resulting in most if not all of the RN battlecruiser force being wiped out, even if at the price of a number of German capital ships. The potential impact on British politics would have been enormous - in 1914/15, the pre-Kitchener years, we're still in the timeframe when there is some political dissent about the war in general.
The attack failed, however, because by accident the British fleet changed its night position on this particular night ... (German troop transports) arrived off Barrow without being noticed, but two submarines happened to be leaving that morning for their station, having just been completed at the works. These vessels met them at the entrance to the river, and they were all torpedoed.
This brief report is from a naval exercise made during pre-war by the War College in which it was proved that the submarine could have major influence against enemy naval forces operating off the coast of Britain.
Imagine the eventual case of Aboukir, Cressy and Hogue on the other side. Half a dozen German armoured cruisers approaching the coasts of England and they are ambushed by two RN submarines. All 6 ships sunk or severly damaged.
The entire problem was that this kind of doctrine, supported by Fisher and friends, found very little support in the Admiralty and when Fisher got to be First Lord he was seriously influenced by the heavy gun school...though he instructed still to rise the production of destroyers and small coastal forces significantly. And to get matters worst there was the usual RN issue in resolving their own submarine doctrines, in other words, 3 totally different doctrines for which submarines of the time had no capability to cope with all 3 at the same time:
1 - Small submarines with shorter range but in larger numbers for coastal defence and anti-invasion tasks.
2 - Medium range submarines for "eyes of the Fleet" missions.
3 - Long range and endurance submarines for close-blockade to the enemy coasts.
Pretty much everyone was fighting to get their own doctrine on and efforts were, as expected, scattered through the 3 main doctrines leaving none strong enough to deal with its job properly.
