Explosives Dumping Ground, off Castlemartin Range

British military vessels dropped unwanted explosives into the deep water off Castlemartin Range, creating a hidden dumping ground that still lies beneath the Pembrokeshire sea. The modern jars and crates may have sunk without warning, carrying dangerous payloads into the dark. Fishermen and sailors probably learned the exact coordinates through bitter experience rather than public announcement. The range itself became a killing field for live ammunition, while the dumping ground became a quiet graveyard for discarded death.
