A 12x10 negative. A bow view, taken from dead ahead, of a 7,000 ton capacity floating dock beached on the foreshore at Tilbury Ness, Essex. A P.L.A. wreck flag is flying from a pole mast on the starboard side. The dock left the Tyne for Callao in tow of two Dutch tugs on 20 August 1908 but broke her tow off Dungeness and lost much of her holding gear. She was towed back to the Thames on 26 August and was moored to the lower buoy off Gravesend to await a fresh supply of anchors, cables and chains. She broke from her mooring and grounded on the Tilbury side of the river 1 September. She finally sailed in tow with new gear aboard on 18 September and arrived at Callao, via Montevideo, on 2 April 1909.
