On 5 November 1910,[2][3] on her 14th outbound voyage, carrying a mixed cargo including a number of pianos for Chile, Preussen was at 23:35 rammed by the small British cross-channel steamer Brighton 8 nautical miles (15 km) south of Newhaven.[4] Contrary to regulations, Brighton had tried to cross her bows, underestimating her high speed of 16 knots (30 km/h). Preussen was seriously damaged and lost much of her forward rigging (bowsprit, fore topgallant mast), making it impossible to steer the ship to safety.

Brighton returned to Newhaven to summon aid and the tug Alert was sent to assist Preussen. A November gale thwarted attempts to sail or tug her to safety in Dover Harbour. It was intended to anchor her off Dover, but both anchor chains broke, and Preussen was driven onto rocks at Crab Bay, where she sank as a result of the damage inflicted on her. While crew, cargo and some equipment could be saved from Preussen, with the keel broken she was rendered unsalvageable. She sits in 6 metres (3.3 fathoms) of water at 51°8.02′N 1°22.17′E. The Master of Brighton was found to be responsible for the accident and lost his licence as a result. A few ribs of Preussen can be seen off Crab Bay at low spring tides.

Wow, that captain messed up big time.
