Events

On 23 March 1916, Sea Serpent struck a mine laid by the German submarine UC-6, commanded by Matthias Graf von Schmettow, and sank off Folkestone Pier, at approximately 51°02’N, 01°12’E. At least two crewmen are recorded as lost: fireman George James Anderson, aged 24, and mess room boy Frederick William Barrow, aged only 16. For divers, this is a classic Channel war-loss: a modest merchant steamer, a practical cargo, a minefield off the Kent coast, and a wreck with the quiet weight of ordinary men caught in extraordinary danger.

On 28 July 1894, Castor was on passage from Smyrna, now Izmir, to Amsterdam, having called at Algiers, when she was caught in dense fog off Dungeness / Folkestone and collided with the German barque Ernst. She was struck amidships and sank, but her 25 crew and 3 passengers were all saved. Her cargo gives this wreck its real intrigue: 14 Greco-Roman sculptures and inscriptions, packed in two crates for the Rijksmuseum van Oudheden in Leiden. Divers later recovered several second-century marble pieces from the wreck, including sculptured heads and funerary monuments. Today, Castor is a cracking dive with a rare story: a Dutch steamer, a Channel collision, and classical antiquities lying in the silt like history had dropped its handbag

On 4 January 1918, Nunima was on passage from Bilbao to Middlesbrough with a cargo of iron ore when she sank after a collision off Folkestone, reported variously as with P19 or an unidentified Royal Navy torpedo boat. UKHO-derived wreck data places the wreck at about 50°58.304'N, 1°08.678'E, lying upright and largely intact in roughly 32 metres, with a least depth of around 19 metres over the wreck. No lives were lost, which is a rare mercy in these Channel stories and frankly suspiciously decent of history for once. For divers, Nunima is a big, upright First World War merchant steamer with cargo history, scale, structure and a proper Dover Strait collision story. A solid wreck with presence.

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".
