Example Input: Question: What was the name of father of the man who blew up part of the railroad? Passage:E11 was on her second tour when, on 6 August it successfully torpedoed the Turkish torpedo cruiser , causing serious damage. Two days later 8 August 1915 as a new British landing was underway at Suvla, E11 torpedoed the antiquated Turkish pre-dreadnought battleship off Bulair at the northern entrance to the Dardanelles. The ship sank with the loss of 21 officers and 237 men. Barbaros Hayreddin was one of two Ottoman battleships sunk during the campaign. Visiting Constantinople again, E11 sank a Black Sea collier Isfahan as it was preparing to unload — a significant blow as coal was the main fuel source and supplies were scarce. Moving into the Gulf of Izmir, on the night of 20 August, E11's first officer, Lieutenant Guy D'Oyly-Hughes, swam ashore and blew up a section of the Constantinople–Baghdad railway line, a feat for which he was awarded the Distinguished Service Cross (United Kingdom). Navigating Officer Lieutenant Robert Brown was also awarded the Distinguished Service Cross (United Kingdom). A reservist from the Merchant Navy, Brown had famously been born rounding the Cape Horn on the clipper John Gambles, the sister ship to the more famous Cutty Sark.
