Well Jacky Fisher had good and bad points. Unfortunately he was one of the few who didn't know this.

His battle cruisers were fine if they didn't come near any other ships armed with similarly large guns. But they did, with disastrous consequences.

HMS Swift (1908) was his idea. This was a very large destroyer designed for about 36 knots (Fisher claimed 38). Twice the size of contemporary destroyers, it was almost all engine! It was a very expensive way of getting 4-4" guns and 2-18" torpedo tubes into battle.

When Churchill brought him back he started with his battle cruisers again (Renown and Repulse) with only 6 inch main belt armour! Then came Glorious, Courageous and Furious which he called 'large light cruisers' as he wasn't allowed any more battle cruisers. Very large at 18,000 tons! They were known as Spurious, Outrageous and Curious by the poor chaps who had to man them.

And when he thought that the Germans had fast 'fleet' submarines he had to have faster ones. The only to get the speed he wanted at the time was by using steam propulsion and that lead to the disastrous K class, possibly the most ill-fated class of ships ever.

Like Fisher, Churchill was a keen self-publicist. But I'm not decrying that they both did some good. They both had plenty of energy when energy was important to have. And Churchill could put over a good speech (even if he didn't write them, and that much of his books). The UK needed a figurehead in WW2 and he did the job ideally. But I can't help thinking that he is remembered as a 'great man' because he so often told people that he was. He still couldn't understand why the electorate rejected him so emphatically after the war was over. And he still couldn't catch Peter the Painter!
