Not to our knowledge. The vessels that are within Canadian territorial waters—the nine warships and the 10 merchant ships—were sunk there either by U-boats, which came very close, as we all know, or by collision, when something happened and something went wrong on the vessel, something to do with the enemy at the time. We know the locations of those 19. We know of none from other countries. Most of those merchant ships were taking part in two convoys during the war.
