1921 | K15 | K15 was moored alongside the light cruiser HMS Canterbury, in the tidal basin at Portsmouth. Most of the crew were on leave when a watch keeper discovered that the submarine was sinking, with the stern already awash. The watch were quickly roused and scrambled aboard the Canterbury. The submarine slowly submerged amid streams of bubbles. The accident was caused by hydraulic oil expanding in the hot weather and contracting as the temperature dropped causing a loss of hydraulic pressure and causing vents to open. |
