Following the victory of the Battle of Tsushima, Japan's erstwhile British ally presented a lock of Admiral Nelson's hair to the Imperial Japanese Navy, judging its performance then as on a par with Britain's victory at Trafalgar in 1805. It is still on display at Kyouiku Sankoukan, a public museum maintained by the Japan Self-Defence Force. Nevertheless, there was a consequent change in British strategic thinking, resulting in enlargement of its naval docks at Auckland, New Zealand; Bombay, British India; Fremantle and Sydney, Australia; Simon's Town, Cape Colony; Singapore and British Hong Kong. The naval war confirmed the direction of the British Admiralty's thinking in tactical terms even as it undermined its strategic grasp of a changing world. Tactical orthodoxy, for example, assumed that a naval battle would imitate the conditions of stationary combat and that ships would engage in one long line sailing on parallel courses; but more flexible tactical thinking would now be required as a firing ship and its target manoeuvred independently.
