Raising the Mary Rose
How a sixteenth-century warship was recovered from the seabed
1On 19 July 1545, English and French fleets were engaged in a sea battle off the coast of southern England in the area of water called the Solent, between Portsmouth and the Isle of Wight. 2Among the English vessels was a warship by the name of Mary Rose. 3Built in Portsmouth some 35 years earlier, she had had a long and successful fighting career, and was a favourite of King Henry VIII. 4Accounts of what happened to the ship vary: while witnesses agree that she was not hit by the French, some maintain that she was outdated, overladen and sailing too low in the water, others that she was mishandled by undisciplined crew. 5What is undisputed, however, is that the Mary Rose sank into the Solent that day, taking at least 500 men with her. 6After the battle, attempts were made to recover the ship, but these failed.
1The Mary Rose came to rest on the seabed, lying on her starboard (right) side at an angle of approximately 60 degrees. 2The hull (the body of the ship) acted as a trap for the sand and mud carried by Solent currents. 3As a result, the starboard side filled rapidly, leaving the exposed port (left) side to be eroded by marine organisms and mechanical degradation. 4Because of the way the ship sank, nearly all of the starboard half survived intact. 5During the seventeenth and eighteenth centuries, the entire site became covered with a layer of hard grey clay, which minimised further erosion.
1Then, on 16 June 1836, some fishermen in the Solent found that their equipment was caught on an underwater obstruction, which turned out to be the Mary Rose. 2Diver John Deane happened to be exploring another sunken ship nearby, and the fishermen approached him, asking him to free their gear. 3Deane dived down, and found the equipment caught on a timber protruding slightly from the seabed. 4Exploring further, he uncovered several other timbers and a bronze gun. 5Deane continued diving on the site intermittently until 1840, recovering several more guns, two bows, various timbers, part of a pump and various other small finds.
1The Mary Rose then faded into obscurity for another hundred years. 2But in 1965, military historian and amateur diver Alexander McKee, in conjunction with the British Sub-Aqua Club, initiated a project called ‘Solent Ships’. 3While on paper this was a plan to examine a number of known wrecks in the Solent, what McKee really hoped for was to find the Mary Rose. 4Ordinary search techniques proved unsatisfactory, so McKee entered into collaboration with Harold E. Edgerton, professor of electrical engineering at the Massachusetts Institute of Technology. 5In 1967, Edgerton’s side-scan sonar systems revealed a large, unusually shaped object, which McKee believed was the Mary Rose.
1Further excavations revealed stray pieces of timber and an iron gun. 2But the climax to the operation came when, on 5 May 1971, part of the ship’s frame was uncovered. 3McKee and his team now knew for certain that they had found the wreck, but were as yet unaware that it also housed a treasure trove of beautifully preserved artefacts. 4Interest in the project grew, and in 1979, The Mary Rose Trust was formed, with Prince Charles as its President and Dr Margaret Rule its Archaeological Director. 5The decision whether or not to salvage the wreck was not an easy one, although an excavation in 1978 had shown that it might be possible to raise the hull. 6While the original aim was to raise the hull if at all feasible, the operation was not given the go-ahead until January 1982, when all the necessary information was available.
1An important factor in trying to salvage the Mary Rose was that the remaining hull was an open shell. 2This led to an important decision being taken: namely to carry out the lifting operation in three very distinct stages. 3The hull was attached to a lifting frame via a network of bolts and lifting wires. 4The problem of the hull being sucked back downwards into the mud was overcome by using 12 hydraulic jacks. 5These raised it a few centimetres over a period of several days, as the lifting frame rose slowly up its four legs. 6It was only when the hull was hanging freely from the lifting frame, clear of the seabed and the suction effect of the surrounding mud, that the salvage operation progressed to the second stage. 7In this stage, the lifting frame was fixed to a hook attached to a crane, and the hull was lifted completely clear of the seabed and transferred underwater into the lifting cradle. 8This required precise positioning to locate the legs into the ‘stabbing guides’ of the lifting cradle. 9The lifting cradle was designed to fit the hull using archaeological survey drawings, and was fitted with air bags to provide additional cushioning for the hull’s delicate timber framework. 10The third and final stage was to lift the entire structure into the air, by which time the hull was also supported from below. 11Finally, on 11 October 1982, millions of people around the world held their breath as the timber skeleton of the Mary Rose was lifted clear of the water, ready to be returned home to Portsmouth.
