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
