Sir Charles Warren (7 February 1840 – 21 January 1927) was a British Army officer of the Royal Engineers. He was one of the earliest European archaeologists of the Biblical Holy Land, and particularly of the Temple Mount. Much of his military service was spent in British South Africa. Previously he was Commissioner of Police of the Metropolis, the head of the London Metropolitan Police, from 1886 to 1888 during the Jack the Ripper murders. His command in combat during the Second Boer War was irredeemably flawed, though he achieved considerable success during his long life in his military and civil posts.

From 1861 to 1865, Warren worked on surveying Gibraltar. During this time he surveyed the Rock of Gibraltar using trigonometry and with the support of Major-General Frome, he created two 8 metres (26 ft) long scale detailed models of Gibraltar.2 One of these was kept at Woolwich, but the other, which survives, is on display at Gibraltar Museum. These models not only depicted the shape of The Rock and harbour but also every road and building on the surface. From 1865 to 1867, he was an assistant instructor in surveying at the School of Military Engineering in Chatham. He was promoted captain for this work.
Western Palestine and Jerusalem
In 1867, Warren was recruited by the Palestine Exploration Fund to conduct Biblical archaeology "reconnaissance" with a view of further research and excavation to be undertaken later in Ottoman Syria, but more specifically the Holy Land or Biblical Palestine. During the PEF Survey of Palestine he conducted one of the first major excavations at the Temple Mount in Jerusalem, thereby ushering in a new age of Biblical archaeology. His most significant discovery was a water shaft, now known as Warren's Shaft, and a series of tunnels underneath the Temple Mount.34
Warren and his team also improved the topographic map of Jerusalem5 and made the first excavations of Tell es-Sultan, site of biblical city of Jericho.6 Some of the sites listed on Warren's topographic map, particularly that of Acra (where he places it in the Upper City,7 contrary to Josephus who places it in the Lower City), have since been corrected and updated.8
In 1870, Warren returned to Britain, where he began writing a book about archaeology.9 His findings from the expedition would be published later as The survey of Western Palestine: Jerusalem (1884), written with C. R. Conder.10 Other books by Warren about the area include The Recovery of Jerusalem (1871), Underground Jerusalem (1876) and The Land of Promise (1875).11
Warren's most significant contribution is his exploration of a subterranean shaft in Jerusalem and which is now named after him, viz., Warren's Shaft. A 2013 publication, The Walls of the Temple Mount, provided more specifics about Warren's work, as summarised in a book review.12
... he concentrated on excavating shafts down beneath the ground to the level of the lower parts of the external Temple Mount walls, recording the different types of stonework he encountered at different levels and other features, such as Robinson’s Arch on the western side and the Herodian street below it. ... in 1884 the PEF published a large portfolio of 50 of Warren's maps, plans and drawings titled Plans, Elevations, Sections, etc., Shewing the Results of the Excavations at Jerusalem, 1867–70 (now known as the 'Warren Atlas').
In December 1884, by now a lieutenant-colonel,13 Warren was sent as HM Special Commissioner to command a military expedition to Bechuanaland, to assert British sovereignty in the face of encroachments from Germany and the Transvaal, and to suppress the Boer freebooter states of Stellaland and Goshen, which were backed by the Transvaal and were stealing land and cattle from the local Tswana tribes.
In 1885, Warren was appointed commander at Suakin in 1886. A few weeks after he arrived, however, he was appointed Commissioner of Police of the Metropolis following Sir Edmund Henderson's resignation. The exact rationale for his selection is still unknown. Up to that time, and for some time into the 20th century, the heads of Scotland Yard were selected from the ranks of the military. In Warren's case, he may have been selected in part by his involvement in discovering the fate of Professor Palmer's expedition into the Sinai in 1883. If so there may have been a serious error regarding his "police work" in that case, as it was a military investigation and not a civil style police operation.
The Metropolitan Police was in a bad state when Warren took over, suffering from Henderson's inactivity over the past few years. Economic conditions in London were bad, leading to demonstrations. He was concerned for his men's welfare, but much of this went unheeded. His men found him rather aloof, although he generally had good relations with his superintendents. At Queen Victoria's Golden Jubilee in 1887, the police received considerable adverse publicity after Miss Elizabeth Cass, an apparently respectable young seamstress, was (possibly) mistakenly arrested for soliciting, and was vocally supported by her employer in the courts.
Friction
To make matters worse, Colonel Warren, a Liberal, did not get along with ConservativeHome SecretaryHenry Matthews, appointed a few months after he became Commissioner. Matthews supported the desire of the Assistant Commissioner (Crime), James Monro, to remain effectively independent of the Commissioner and also supported the Receiver, the force's chief financial officer, who continually clashed with Warren. Home OfficePermanent SecretaryGodfrey Lushington did not get on with Warren either. Warren was pilloried in the press for his extravagant dress uniform, his concern for the quality of his men's boots (a sensible concern considering they walked up to 20 miles a day, but one which was derided as a military obsession with kit), and his reintroduction of drill. The radical press completely turned against him after Bloody Sunday on 13 November 1887, when a demonstration in Trafalgar Square was broken up by 4,000 police officers on foot, 300 infantrymen and 600 mounted police and Life Guards.
Warren was appointed a Knight Commander of the Order of the Bath (KCB) on 7 January 1888. Later that year he renamed the four District Superintendents (ranking between the Superintendents and the Assistant Commissioners and each in charge of a group of divisions) Chief Constables, adding a Chief Constable at the head of the Met's Criminal Investigation Department (CID) in 1889.14 Monro insisted that the first holder of the latter post should be a friend of his, Melville Macnaghten, but Warren opposed his appointment on the grounds that during a riot in Bengal Macnaghten had been "beaten by Hindoos", as he put it. This grew into a major row between Warren and Monro, with both men offering their resignation to the Home Secretary. Matthews accepted Monro's resignation, but simply moved him to the Home Office and allowed him to keep command of Special Branch, which was his particular interest. Robert Anderson was appointed Assistant Commissioner (Crime) and Superintendent Adolphus Williamson was appointed Chief Constable (CID). Both men were encouraged to liaise with Monro behind Warren's back.
Jack the Ripper
Colonel Warren's biggest difficulty was the Jack the Ripper case. In his book, Abberline: The Man Who Hunted Jack the Ripper, author Peter Thurgood indicates that Warren was criticised during the investigation. He was blamed for failing to track down the killer, accused of failing to offer a reward for information (although that plan was actually rejected by the Home Office), accused of assigning an inadequate number of investigators (patently untrue) and favouring uniformed constables instead of detectives (probably untrue). In response, Warren wrote an article outlining his views and the facts for Murray's Magazine; the article also indicated that he favoured vigilante activity in finding the Ripper. He was censured by the Home Office for revealing the workings of the police department and for writing an article without permission. 15
As recently as 2015, a book about the Ripper case by Bruce Robinson castigated Warren as a "lousy cop" and suggested that a "huge establishment cover-up" and a Masonic conspiracy had been involved. In its book review, The Guardian stated that "most historians put the police's failure to catch the Ripper down to incompetence" but did not specifically name Warren in this context.16
Warren finally had enough of criticism and resigned – coincidentally right before the murder of Mary Jane Kelly on 9 November 1888. But he agreed to stay on until his successor was in place and continued in post until 1 December. He then returned to his army career. Nearly every superintendent on the force visited him at home to express their regret over his resignation. One attendee praised Warren for his thoughtfulness and his caring for the men in his command.17
Later military career and Boer War
Warren returned to military duties and in 1889 was sent to command the garrison in Singapore, with a simultaneous promotion to the rank of Major-General in 1893 remaining in Singapore until 1895. After returning to England, he commanded the Thames District from 1895 to 1898, when he was promoted to lieutenant general in October 189718 and was moved to the Reserve List.19
Royal Engineer Yacht Club
Watermanship being one of the many skills required of the Sapper led to the formation of a sailing club at the School of Military Engineering in 1812 and later to the development of cutter rowing teams. Construction of a canal linking the Thames and Medway rivers in 1824 gave the Royal Engineers an inland waterway to practice these skills, with the officer responsible for the canal drawn from the Corps of Royal Engineers. In 1899 as General Officer Commanding the Thames and Medway Canal, General Sir Charles Warren presented a challenge shield for a championship cutter race on the River Medway against the Royal Navy. The Sapper teams were drawn from members of the Submarine Mining School, but when the service was disbanded in 1905, the tradition of cutter rowing was continued by the fieldwork squads. The REYC continues to compete against the Royal Navy Sailing Association annually to this day. The club developed and became the Royal Engineer Yacht Club in 1846, making it one of the most senior yacht clubs in the United Kingdom. The REYC continues to this day, operating three club yachts and competing on behalf of the Corps at races around the world. The club is one of the oldest sports clubs in the British Army.
Second Boer War
On the outbreak of the Second Boer War in November 1899, he returned to the colours to command the 5th Division of the South African Field Force. The decision to give command to Warren was surprising. By then, Warren was 59 years old, was said to have a "disagreeable temper", had little experience leading troops in battle and did not get along with his superior, General Sir Redvers Buller.19
In January 1900, Warren bungled the second attempted relief of Ladysmith, which was a west flanking movement over the Tugela River. At the Battle of Spion Kop, on 23–24 January 1900, he had operational command, and his failures of judgment, delay and indecision despite his superior forces culminated in the disaster. Farwell highlighted Warren's fixation with the army's oxen and his view that Hlangwane Hill was the key to Colenso.20 Farwell suggested Warren was "perhaps the worst" of the British generals in the Boer War and certainly the most "preposterous".21 He was described by Redvers Buller in a letter to his wife as "a duffer", responsible for losing him "a great chance".
From 1908, Warren became involved with Baden-Powell in the creation of the Boy Scout movement.24 He was also involved with another group, the Church Lads' Brigade 25 and 1st St Lawrence Scout Group, then called 1st Ramsgate – Sir Charles Warren's Own Scouts 26
He had previously authored several books on Biblical archaeology, particularly Jerusalem, and also wrote "On Veldt in the Seventies", and "The Ancient Cubit and Our Weights and Measures". He died of pneumonia, brought on by a bout of influenza, at his home in Weston-super-Mare, Somerset, was given a military funeral in Canterbury, and was buried in the churchyard at Westbere, Kent, next to his wife. A biography of him was published in 1941 by his son-in-law the Revd Watkin Wynn Williams.27
Fictional portrayals
Warren was played by Basil Henson in the 1973 miniseries Jack the Ripper. He was played by Anthony Quayle in the 1979 film Murder by Decree, which features the characters of Sherlock Holmes and Doctor Watson in a dramatisation of a conspiracy theory concerning the Ripper case. In the 1988 made-for-TV mini-series Jack the Ripper, which followed the same conspiracy theory as Murder by Decree, he was played by Hugh Fraser. The mini-series shows his final act as commissioner ordering lead detective Fred Abberline to suppress his findings on the investigation in order to protect the royal family from scandal. In the 2001 film From Hell he was played by Ian Richardson.
