Question: What can you tell me of the Thames River Police? How active were they in the Regency era? Etc.
Response: When I was writing The Prosecution of Mr. Darcy’s Cousin: A Pride and Prejudice Mystery LOTS of research was required, especially information about the policing practices in Regency Era London. One of my discoveries was the River Thames Police.

In the 18th Century, importers docking along the River Thames in London had lost £500.000 annually as cargoes were unloaded on the unprotected River Thames. In 1797, an Essex Justice of the Peace, farmer, and inventor from Great Stanbridge, Mr John Harriott, came up with a plan to change all that. Mr Patrick Colquhoun, LLD. (the principle magistrate of Queens Square Police Office), advocated for Harriott’s plan with the West India Merchants and the West India Planters Committees to finance preventative policing of the central shipping area of the Thames. The government approved the establishment of the Marine Police on 2 July 1798 in Wapping High Street. Originally, the West India Merchants Company Marine Police Institute was to operate for just one year, but as the Government was involved with the war with France, the time was extended.
A Surveyor (equivalent rank of an Inspector, by today’s standards) and three waterman Constables under the direction of a Superintending Surveyor manned each of the rowing galleys. The Superintending Surveyor also had a supervision galley with a crew of four. The Surveyors had taken an oath to the Crown and were issued an excise warrant by the Customs and Excise Service.
In addition, ship and quay guards were employed on a part-time basis. They were only employed when the West India fleets were on the river. Otherwise, they were dismissed until needed again. These “guards” were supervised by the boat patrols, which eventually became the first River Police Special Constables. Initially, it cost £4.200 to set up the force (hires and premises), but , by all estimates, they had saved £122.000 in cargo and had saved a dozen individuals.
Only numbering in the low 50s, these Officers were expected to control some 30.000 + people who made their living on the river. One must realize a large portion (some 25-35%) of that 30.000 were likely criminals. Unfortunately, during the first six months, a riot took place outside the Office, and a crowd of 2000+ threatened to burn the building to the ground, with officers and magistrates inside. Harriott managed to quell the riot. Sadly, Gabriel Franks (Master Lumper) was shot and killed – the first recorded police death. “After a year, Harriott was able to give his first report to the Home Office stating ‘instead of many waterman’s boats hovering nearby while ships unloaded, the river now appears quiet and peaceful, except for those going about their lawful business.” (River Thames Police – History – Establishment)
Ship owners convinced the government of the value of the Marine Police. Letters from importers, shipmasters, and wharf owners praised the deterrent tactics of the boat patrols and quay guards. On 28 July 1800, Parliament passed the Marine Police Bill making the river police a public domain. The bill also increased the number of officers to 88. “They were taken with the Magistrate John Harriott to be directly under the control of the Home Secretary, who used their hard won experience throughout the whole of the Metropolis until such times as the Metropolitan Police were formed.” In 1800, Patrick Colquhoun released a book entitled The Commerce and Policing of the River Thames. “As the only police body extant whole chapters were included about criminals of the Thames, its policing and the effect. The book was widely read and approved of, so much so that many other police forces were formed throughout the world on his principles, the most famous being Dublin, New York and Sydney, Australia.” (River Thames Police – History – Government Support)
By the time the Metropolitan Police began in 1829, the River Thames Police had grown in numbers and in stations. They had extended their jurisdiction to above Chelsea and down to Woolwich and had acquired two old naval vessels to patrol the extent of the Thames. “In 1817 an excise “Cutter” was purchased to patrol the lower reaches as far as the Downs, firstly to protect the Kings stores at Sheerness, a Magistrate with powers in the surrounding counties was then essential to empower the River Police to prevent such crimes and in particular crimping. Winter for the officers patrolling in open boats was most rigorous.” (River Thames Police: History)
By 1839, the Metropolitan Police, under Commissioners Sir Richard Mayne and Sir Charles Rowan, who operated with the Home Secretary’s permission, had unified other police bodies in London, including the Bow Street Runners, Horse patrols, and the River Police. The only exception was the City of London Police force, which was founded in 1834 and remains a separate entity even today.
With this unification, the Thames Magistrate Office was moved to Arbour Square and renamed the Thames Magistrates Court. “Thames Division of the Metropolitan Police was built on the officers and experience of its earlier force. It was always that the land police were formed (and indeed their uniform suggests it) on the pattern of an army regiment and the River Police on the pattern of a Royal Navy ‘man of war’ (Hence their reefer jackets and naval boaters.).

For the next forty years the rowing galleys and sailing patrols continued and were found adequate, while the river trades slowly became merchandised and to a large extent iron replaced wood. In 1878 the loss of over 600 lives in the disastrous collision between the paddle steamer “Princess Alice” and the collier “Bywell Castle” made it obvious that at least some powered craft were necessary. In 1884, two steam launches were purchased for supervisory purposes and later a third was found necessary.” (River Thames Police: History)
Something else one might want to consider, if it matters to the story being written, is how long it would take from the time a person, or a body, went into the river to the time it was found. The Thames is a tidal river, which means that at high tide, the water actually flows upstream, as far as Teddington, while at low tide it flows downstream, as one would expect. Since the lower reaches of the Thames are tidal, there is more salt in the water, which would make anything thrown into it more bouyant than something thrown into fresh water.
Previous I read the book, Thames: A Biography, by Peter Ackroyd. It is a fascinating read, and one thing he has noted is the vagaries of the currents in the Thames. Some tests were done which show clearly that something which was tossed in the river in the vicinity of London could take from three to six weeks to travel downstream to the area known as the Port of London.
Charles Dickens has a character (Gaffer Hexham) in Our Mutual Friend who scours the Thames in a boat for dead bodies, and anything else of value that he can turn up. It has been a long time since I read Dickens’s tale, so I do not recall if he turned in the bodies for money or if he just kept what valuables he found on them. Before Dickens’s time, the bodies had value at medical schools, but, otherwise, they were useless, meaning in a Regency based tale, one could steal a body and not be arrested, but stealing the “Sunday best” the person wore could have you arrested and jailed or even transported.
The Thames river police were the ones who were supposed to be notified if bodies were found in the river. Accidental drownings and suicides were the most frequent causes of death.
Bodies were found elsewhere, for instance, in the Serpentine and other rivers and bodies of water as well. In those cases the nearest magistrate was notified. He was supposed to notify the coroner. The Coroner had to be informed of all deaths occurring without the presence of a physician/surgeon.

Disappointed in his military ambitions, Gwinnett continued to lead the opposition to the Christ Church Parish coalition, and when his followers gained control of Georgia’s Provincial Congress, they succeeded in electing him Speaker. He played a key role in the passage of the Georgia Constitution of 1777 and began to purge the military of officers whom he and his followers deemed less than zealous in their enthusiasm for the Whig cause. This brought him into conflict with Lachlan McIntosh. After the death of Georgia’s president and commander-in-chief, Archibald Bulloch, in February 1777, the Council of Safety appointed Gwinnett to succeed him.
Gwinnett’s signature is one of the rarest and most valuable of the signers of the Declaration of Independence. In 1979 a letter signed by Gwinnett brought $100,000 at a New York auction; its value was estimated in 1983 to be up to $250,000.
