French Sailors visiting the Imperial German Navy SM UC-61 Type UC II minelaying submarine stranded on the beach near Wissant, Pas-de-Calais, France, in August 1917.
UC-61 was ordered on the 12th of January 1916, laid down on the 3rd of April 1916 by A.G. Weser of Bremen, and was launched on the 11th of November 1916. She was commissioned into the German Imperial Navy on the 13th of December 1916.
She had a deck gun, three torpedo tubes and carried six naval mines.
She had only 7 months of activity but in 5 patrols UC-61 was credited with sinking 11 merchant ships, either by torpedo or by mines laid.
Captain Georg Gerth, commander of SM UC-61 was on his 5th combat mission on the 25th of July 1917. The mission's objective was to break through the French-British Dover Barrage and then lay mines in the shipping routes to the ports of Boulogne and Le Havre. Capt. Gerth had tried to navigate close to the coast between Cap Blanc Nez and Cap Gris Nez. However, he had overestimated the depth of the water along the route. Suddenly, the crew heard the keel grating on the sand. The U-boat was stranded on a sandbank and irretrievably lost.
Capt.Gerth new that it would not take long for the conning tower to come to the surface due to the falling tide. His only option was to abandon ship, destroy her and surrender to the enemy.
In the darkness of that night, nearby French customs officers heard the attempts by the crew to scuttle the sub and they alerted the nearest military force, namely the 5th Regiment of Belgian Lancers. The cavalrymen rushed to the scene but the crew managed to break the hull in half with a heavy explosion.
The crew were apprehended and ordered to walk the 20kms distance to Calais, escorted by the Lancers.
The wreck was left with several unexploded naval mines on board.
