1904: HMS Hazard/Fort Blockhouse.

The Admiralty had been dismissive at first of submarines but the American and French work persuaded them to follow suit. A batch of five submarines for testing tactical suitability were ordered in early 1901, built under licence from America by vickersVickers at Barrow-in-Furness, named Holland 1 to 5.

Captain Reginald Bacon, the first Inspecting Captain of Submarines, concluded that these vessels were too small, resulting in a larger Holland 6 being built. Reflecting the decision to identify the vessel type as A Class, Holland 6 was renamed A-1, becoming the first submarine for the Royal Navy

18-03-1904 Whist on exercise off the Isle of Wight HMS A1 was tasked with 'attacking' HMS Juno. The mock attack began in the early afternoon; HMS Juno had been sighted heading towards Portsmouth Harbour. First to attack were the Holland Boats, after which came A1's turn. As A1 closed in for the kill she was struck on the starboard side, near the conning tower, by the steam ship Berwick Castle, on route from Southampton to Hamburg.

Unaware of the submarines in the area the master of the Berwick Castle reported that he believed he had been struck by a practice torpedo and continued his journey.

It was not until A1 failed to return to harbour that the full scale of the disaster was known
