text_A: The first Q-ship victory was on 23 June 1915, when the submarine HMS "C24", cooperating with the decoy vessel "Taranaki", commanded by Lieutenant Frederick Henry Taylor CBE DSC RN, sank "U-40" off Eyemouth. The first victory by an unassisted Q-ship came on 24 July 1915 when "Prince Charles", commanded by Lieutenant Mark-Wardlaw, DSO, sank "U-36". The civilian crew of "Prince Charles" received a cash award. The following month an even smaller converted fishing trawler renamed HM Armed Smack "Inverlyon" successfully destroyed near Great Yarmouth. The "Inverlyon" was a sailing vessel, without any engines, to which a small 47-mm gun was fitted which could fire a 3-pound round. The British crew fired nine rounds from their 3-pounder into "UB-4" at close range, sinking her with the loss of all hands despite the attempt of "Inverlyon"s skipper to rescue one surviving German submariner.

NO.
