In June 1922 whilst submerged during exercises she was rammed by HMS Vancouver. The Conning tower was badly damaged and although the Vancouver left part of one of her screws embedded in the junction of the conning-tower and the pressure hull there were no breaches. Fortunately there were no casualties

Suddenly there was an almighty thump, as the conning tower of the submarine struck our hull, almost below where we were standing. The stern of the "Grey Rover" was shunted round a few degrees to port and the bow to starboard. On the bridge we were in shock for a few moments with the realisation of what had happened. The propeller was quickly declutched from the engine and I took a position of our ship. The engineers below, who must have had an awful fright, were told what had happened and checked that we had not been holed.
After the narrow defeat of their U-boat fleet in the First World War, the German Navy analyzed their experiences and devised new theories and plans for a future conflict.
The principal result of this study was the development of the daring concept of Rudeltaktik, which involved co-ordinated pack attacks on the Allied convoy systems that had proved so successful in defence
