I would like some information on an interesting tactic used by the British: apparently, several trawlers were converted as "mother ships" for small submarines, which were secured by cables to the surface vessel and remained underwater. As the U-Boat maneuvered to board the trawler, the British sub would launch an underwater torpedo attack. At least one U-Boat was sunk this way, and there may have been more. If anyone has details on what types of subs were used, diagrams, how many conversions were done, and what year the British began using this system, it would be most helpful.
