Hi, This boat was sunk in Operation Deadlight in 1946. she had two aborted attempts before finally being towed out to be sunk. On February 9th and 10th three naval tugs were deployed for the task, HMS Prosperous, HMS Sparkler and HMS Exploiter. The last one is not listed in Lenton's book 'British & Empire Warships of WW2. Is any details, type and pendent number listed? John
