Raising a sunken warship, even in shallow water, has always been a very difficult affair. Even today this remains one of the most difficult tasks facing any navy, as witnessed by the difficulties the Norwegian navy are currently having raising the sunken frigate KMN Helge Ingstad which sank last year. Modern technology definitely helps in the salvage of sunken warships, but even a century ago there were commercial companies who specialised in salvaging ships and despite the work being dangerous, the rewards could be substantial. The Royal Navy did not really have any established salvage equipment or expertise until the First World War and so commercial companies were used when a ship needed salvaging. This image dates, I believe, from the Edwardian era and is printed on extremely heavy card stock. It shows a warship being raised by means of ‘camels’:The camels appear to be a set of flotation bags. Divers would have placed cables under the keel of the ship attached to these bags. Compressed air would then be flooded into the camels which would rise and lift the ship with them:This action appears to have been successful and tugs are waiting to pull the stricken vessel to safety:Whilst the flotation bags have lifted the ship, the freeboard remains miniscule and water is washing over her decks:A large gaggle of workers stand, watching the operations from the vessels upper deck:Sadly I have no context on this image, I am pretty sure it is a British warship and the style suggests it is a late Victorian or early Edwardian warship of a decent size, but beyond that I have no information. Which vessel it is and where and when it was salvaged are a mystery and as ever if you can offer up more information please get in touch.
