It had been U-boats that had been making the news, sinking Allied ships in the Atlantic, but one of three submarines in the Solent would come some way to redressing the balance. The three submarines were Taku, Ursula and Sickle. It is the passage of the latter that we will follow.
One of the great untold stories of the British services is that of the Royal Navy Submarine Service which entered the fray in World War I with 100 underwater craft. Through World War II, where submariners' prospects of returning safely from a mission were only 50:50, the Falklands conflict and the sinking of the Belgrano, to present-day elite machines, the Silent Service has played an enormous part in British defence.
John Parker's in-depth investigation is very much personality led with diaries from the early part of the century to substantial first-person testimony from survivors of wartime heroics (when many VCs were won).
