HMS Pathfinder.  The only one of the four similar Scout classes to be sunk which was mainly owing to the types poor endurance.  She was so short of coal whilst on patrol that she could only manage a speed of 5 knots making her an easy target for the German submarine U 21 and giving her the distinction of being the first warship sunk by submarine attack. hms pathfinder
