The work went on for some three years with occasional interruptions. Warren returned home in 1870, and spent the following year in preparing the results of his work for the Committee of the Fund and for the Press. Sir Walter Besant, in his ‘Twenty-one Years’ Work in the Holy Land,’ writes: ‘It is impossible here to do more than to recapitulate the principal results of the excavations, which are without parallel for the difficulties presented and the courage displayed in overcoming them.... It is certain that nothing will ever be done in the future to compare with what was done by Warren.... It was Warren who restored the ancient city to the world; he it was who stripped the rubbish from the rocks and showed the glorious temple standing within its walls 1,000 feet long, and 200 feet high, of mighty masonry: he it was who laid open the valleys now covered up and hidden; he who opened the secret passages, the ancient aqueducts, the bridge connecting the temple and the town. Whatever else may be done in the future, his name will always be associated with the Holy City which he first recovered.’ So much was this the case that for a long time he was known as ‘Jerusalem Warren.’ In addition to ‘Underground Jerusalem’ he wrote ‘The Temple or the Tomb.’ What high value was placed upon Captain Warren’s services by the Administration of the Fund may be gathered from the following quotation from ‘Our Work in Palestine,’ published by Bentley & Son in 1875, a book which had then reached its eighth thousand:-- ‘Let us finally bear witness to the untiring perseverance, courage, and ability of Captain Warren. Those of us who know best under what difficulties he had to work can tell with what courage and patience they were met and overcome. Physical suffering and long endurance of heat, cold, and danger were nothing. There were besides anxieties of digging in the dark, anxieties as to local prejudice, anxieties for the lives of brave men--Sergeant Birtles and the rest of his Staff--anxieties which we may not speak of here. He has his reward, it is true. So long as an interest in the modern history of Jerusalem remains, so long as people are concerned to know how sacred sites have been found out, so long will the name of Captain Warren survive.’ DOVER, SHOEBURYNESS, AND THE ORDNANCE FACTORIES, 1871 TO 1876
