 Paul Deschamps visited the castle in February 1927 . Since Rey had visited in the 19th century a village of 500 people had been established within the castle . Renewed <unk> had damaged the site : underground vaults had been used as rubbish tips and in some places the <unk> had been destroyed . Deschamps and fellow architect François <unk> attempted to clear some of the <unk> ; General Maurice <unk> assigned 60 <unk> soldiers to help . Deschamps left in March 1927 , and work resumed when he returned two years later . The culmination of <unk> 's work at the castle was the publication of Les <unk> des <unk> en <unk> <unk> I : le Crac des Chevaliers in 1934 , with detailed plans by <unk> . The survey has been widely praised , described as " brilliant and <unk> " by military historian D. J. <unk> King in 1949 and " perhaps the finest account of the archaeology and history of a single medieval castle ever written " by historian Hugh Kennedy in 1994 .
