When John Arbuthnot Fisher returned to the Admiralty as First Sea Lord on Trafalgar Eve, I904, it was obvious to all who followed naval affairs that a period of major reform would ensue. Apart from Lord Charles Beresford, Fisher was the best known naval personality in the land. As Commander-in-Chief Mediterranean he had greatly improved the speed, gunnery, and tactical efficiency of the Fleet, while as Second Sea Lord and subsequently C-in-C Portsmouth he had already, by his control over the appointments of service personnel, laid the groundwork for reform.

In it, Nelson is seen clambering back on to his column at the sight of Fisher entering the Admiralty; the caption reads: 'I was on my way down to lend them a hand myself, but if Jacky Fisher's taking on the job there's no need for me to be nervous, I'll get back on my pedestal.' The feeling was well founded. In his years as First Sea Lord almost every corer of the Admiralty was rigorously examined and overhauled.
