Tonfanau (pronounced ton-van-eye) is an old military camp, just half a mile from Tywyn, used during the Second World War as an anti-aircraft training facility; a row of gunning placements pointing out to sea still runs along the shore. The trainees were supplied with targets by the nearby RAF Tywyn who riskily towed disposable gliders(the targets) using Hawker Henleys. There is one story of a Henley towing a target for the camp when the Royal Artillery were operating a new radar system and the gunners did not bother waiting for the second blip before letting fly. As rounds exploded around him, the pilot hastily radioed down to the Army saying “that they were towing the target; not pushing it”. Not surprisingly, the preferred aircraft for artillery training was the remote-controlled Queen Bee which was an unmanned version of the Tiger Moth.
