A German submarine from the First World War began to emerge from the water near the beach in northern France. She was noticed by one of the nearby guides. Historians say that the UC61 was flooded by a crew after a mine exploded in July 1917. The submarine left Zeebrugge in Belgium and was heading to Boulogne-sur-Mer and Le Havre to lay mines. But, according to a local newspaper, a crew of 25 people was forced to leave the ship at sea.
