The Earl of Abergavenny was heavily laden with over 400 passengers and a valuable cargo of porcelain and sterling worth £20,000. After various misadventures in the Chanel including a collision, the Abergavenny, having left Portsmouth and while being piloted through the Portland Roads on the 5th February during worsening weather and failing light, was driven onto the Shambles, a bank of sand and gravel about 1.9 miles (3km) out from Weymouth beach. The Commander John Wordsworth, brother of the poet William Wordsworth, was among those lost. The inscription details attempts to recover property using the latest diving technology.
