The seventeen miners working in a small Bryn Gwiog lead mine in North Wales near the town of Denbigh broke through into an nearby disused and flooded mine. Torrents of water filled their diggings immediately and only one man was able to seize a rope and haul himself to the surface. The mine was completely filled with water thought to be around 240 feet deep. (By John Osborne)
