It was a 'mission impossible'...On 25 April 1915 - the day the Anzacs landed at Gallipoli - Lieutenant Commander Dacre Stoker set out as captain of the Australian submarine AE2 on a mission to breach the treacherous Dardanelles Strait with the intention of disrupting Turkish supply lines. Facing dangerous currents, mines and withering enemy fire, Stoker and his men succeeded where British and French submarines had come to grief. Stoker's achievement meant much in military terms, and even more emotionally in boosting the morale of embattled Allied troops. But what was proclaimed at the time as 'the finest feat in submarine history' has since sunk into oblivion. Now, finally, this book tells the story of a remarkable naval hero and the men under his command. And AE2 herself, still lying intact on the floor of the Sea of Marmara, is celebrated as the most tangible relic of Australia's role at Gallipoli. A definitive historical work detailing the life of an important figure in 20th-century naval history: Dacre Stoker.
