That doesn;t apply for all countries. For instance, in USSR, where Ukriane is right now, in Sevastopol, the Italian ship, renamed "Novorossiysk" was blown up. A lot of controversy there, but the fact remains. Most of the crew below decks died. They salvaged the ship, since it was blocking the harbor, and took the skeletons out. So much for disturbing the graveWhat I don't understand is how they were allowed to get the container from the wreck. It came from U-1, which was sunk with all hands lost, so surely the wreck is a protected war grave?
