Events

On 10 May 1918, Amplegarth was on passage from Dunston-on-Tyne to St Nazaire with a cargo of coal when she struck a mine laid by the German minelaying submarine UC-71, commanded by Oberleutnant zur See Walter Warzecha. She sank about 1 mile west-south-west of Dover Harbour. The best Cardiff shipping summary I found records no lives lost, which is a blessedly rare line in a First World War wreck note. For divers, this is a proper Dover war wreck: a big merchant steamer, a working cargo, a UC-boat minefield, and a loss right on the doorstep of one of the busiest wartime ports in Britain.

Efford sank after the collision, reportedly cut in two, and her remains are known as two separated wreck sections off Dover. That makes her an especially interesting dive: not a grand liner or warship, but a compact coaster with a dramatic physical story written into the seabed. For divers, Efford offers exactly the sort of Channel wreck that rewards close inspection: broken structure, wartime context, collision damage, and the odd thrill of knowing the bow and stern are not necessarily where polite naval architecture intended them to be.

On 3 December 1915, Étoile Polaire struck a mine and sank off the South Goodwins. The minefield is recorded as having been laid by the German minelaying submarine UC-1, commanded by Kapitänleutnant Egon von Werner. Her wreck has had a confusing afterlife: Canterbury Divers and Historic England both note that a site once listed as HMT Cayton Wyke was positively identified as Étoile Polaire when her bell was recovered. The wreck lies in about 27 metres, stands up to 5 metres proud, and is described as fairly intact, with a blown-off bow, open holds, intact stern and surviving superstructure. For divers, this is a cracking Dover Patrol wreck: compact, atmospheric, strongly identified, and close enough to the Goodwins to add that little pinch of "this place has been eating ships for centuries".
