His Majesty's or HM Armed Smack Inverlyon was a fishing smack that was converted to a Q-ship during the First World War. Q-ships served as decoys to lure German submarines near enough so that concealed weapons could be brought to bear and sink the submarines. On 15 August 1915, Inverlyon succeeded in luring German submarine UB-4 within range and sinking her with nine shots from her gun. The Royal Navy Gunner in command of the vessel, Ernest Martin Jehan, received the Distinguished Service Cross and members of Inverlyon's crew shared the bounty offered for German submarines. After Inverlyon's Q-ship career ended, she returned to fishing, but was sunk by U-55 on 1 February 1917.
