On 21 July 1917 an Anglesey seaman, William Williams, received the Victoria Cross, Britain's foremost gallantry award. The citation on the award read 'selected by the ship's company of one of H.M. ships to receive the Victoria Cross under Rule 13 of the Royal Warrant'.
On 7 June 1917, HMS Pargust (one of the Q ships) was out in the Atlantic Ocean when her engine room was damaged by a torpedo fired from a U-boat. The explosion loosened the gun covers and Seaman Williams, with great presence of mind, took the whole weight on himself and physically prevented the covers from falling and betraying the ship to the enemy.
