Thanks to the generous assistance of the National Maritime Museum, the curator of Kresen Kernow (home to the Cornish History Archives), and Cornwall Council’s Historic Environment Planning Department, we can uncover a remarkable chapter of Cornish maritime history.
In the 1700s, John and Harry Carter were officially regarded by the authorities as men operating outside the law. Yet to the local Cornish population, starving and struggling in harsh conditions, the brothers were seen as Robin Hood figures of the Cornish coast. The Royal Navy referred to them as “brothers in arms,” while His Majesty’s Customs and Excise Officers described them as “upright men.” Most remarkably, the Carters were credited with saving the lives of seventeen sailors.
This was a time of extreme hardship: even a single pot of tea for a family would have cost the equivalent of £300 today. Against this backdrop of poverty and scarcity, the Carters’ actions carried profound significance.
This is just the beginning of a fascinating story—one that explores the lives of the Carter family as smugglers, the complex moral landscape of the time, and the courage of the Customs and Excise men who patrolled the perilous Cornish coastline.

As a child, John Carter earned the nickname “the King of Prussia” because he always insisted on being the “king” during games with his brothers. The nickname was inspired by the real King of Prussia, a prominent German military commander admired during Carter’s lifetime.
According to the National Maritime Museum, Prussia Cove was later named after John Carter. The museum’s Maritime Views website perfectly documents his connection to the area and shows how his childhood nickname became permanently linked to the cove.

The Carter Brothers: Potential and Reputation
Folliott-Stokes wrote in 1928 that if circumstances had been different, and if the Carter boys’ parents had been wealthy, John would have been sent to Parliament and Harry to the Navy. He concluded: “England would have doubtless gained a subtle diplomatist and a distinguished Admiral,” reflecting the Carters’ reputation for scrupulous fair dealing and quick-wittedness.

John Carter was described as “the Prince of smugglers, daring and imaginative, a man of his word.”

In 19th century Cornwall, the county relied heavily on two main industries: mining and fishing. The original Cornwall Coat of Arms even depicted a fisherman and a miner, a symbol still recognised today.
A key part of Cornwall’s fishing trade was the pilchard, or large sardine, which was mostly exported to the Mediterranean. Preserving these fish required large quantities of high-quality salt, imported from the coasts of Brittany and Spain.
In the late 18th century, Cornish fishermen faced a crisis. Massive tax increases to fund the war with France made basic goods unaffordable: tea was taxed at 110%, and duties on brandy and gin were 250%. Salt, essential for preserving pilchards, became 40 times more expensive than untaxed salt, pushing already impoverished families toward starvation.
The Carter brothers, along with other local smugglers, recognised a solution. By bringing in salt and other goods from France and distributing them locally without taxes, they helped the community survive. Their actions were so widely supported that local courts rarely, if ever, convicted them.

According to the archives at Kresen Kernow, both John and Harry Carter served in the Royal Navy aboard HMS Norfolk. This was an 80-gun ship of the line, with guns arranged across three decks, launched in 1740. Their naval service gave the brothers experience and skills that would later influence their daring exploits along the Cornish coast.

The photo above shows record numbers 4 & 5, listing John and Harry Carter on the ship’s manifest of HMS Norfolk. This record is preserved on microfiche at Kresen Kernow, providing official documentation of the brothers’ naval service.

In 1777, Harry Carter was granted Letters of Marque by the British Admiralty. These official documents authorized him to operate as a privateer, allowing him to capture enemy French ships legally during wartime. The letters effectively made Harry a state-sanctioned privateer, giving him the legal backing to attack and seize enemy vessels while sharing the profits with the Crown.
Harry captained his family-owned cutter, the Swallow, under these letters, combining his knowledge of the seas with his smuggling skills. Later, in 1780, he obtained additional letters of marque for the Phoenix, continuing his ventures at sea under Admiralty authority.
Letters of Marque were a vital tool in the 18th century, blurring the line between naval service and private enterprise, and demonstrating Harry’s trusted position with the British authorities despite his reputation as a smuggler.
By 1777, at the age of 28, Harry Carter had been granted Letters of Marque, official commissions from the Admiralty allowing him to act as a privateer—essentially authorizing him to capture enemy ships on behalf of Britain during the war with France. Sailing as Master of the family-owned 200-ton cutter, the Swallow, Harry carried out these duties with skill and daring.
In December 1777, he officially received the Letters of Marque for the Swallow, but by January 1778, he was arrested in St Malo, beginning the first of three spells in French imprisonment. Later, in May 1780, he obtained Letters of Marque for the 50-ton cutter Phoenix, engaging in trade and smuggling before being captured by the armed ship Three Brothersoff the Gower Peninsula in Wales. Following twelve weeks in prison, Harry was curiously released thanks to intervention from influential friends via the Lords of the Admiralty.
However, his luck ran out on a fateful voyage off the French coast. During the journey, his cutter lost its bowsprit and had to put into St Malo for repairs, unaware that France, now allied with the revolting American colonies, was at war with England. Carter sailed his heavily armed cutter into a trap, and he, his brother John, and the crew were made prisoners. Their ship and cargo became a French prize of war.
John Carter, nicknamed the “King of Prussia,” attempted to negotiate their release, but his efforts failed. The brothers endured a hard and tedious captivity, using their time resourcefully: they learned French, and Harry studied navigation, skills that would serve him well in the years to come.
After two years in captivity, freedom finally came through a prisoner exchange, allowing the Carter brothers to return to England and continue their adventurous and remarkable lives on the Cornish coast

In the 19th century, Cornwall relied on two main industries: mining and fishing. The original Cornwall Coat of Arms even featured a miner and a fisherman, and Cornwall Council continued to use this emblem until recently.
A key part of Cornwall’s fishing economy focused on pilchards (large sardines), most of which were exported to the Mediterranean. Preserving these fish required thousands of tons of high-quality salt, imported from the coasts of Brittany and Spain.
In the late 18th century, the pilchard industry faced crisis. A series of massive tax rises—tea taxed at 110% and brandy and gin at 250%—pushed ordinary people to the brink. The cost of salt alone rose 40 times above its untaxed price, leaving the local population unable to afford it and at risk of starvation.
Smugglers like the Carter brothers realized that it was possible to sail to France in a day or two, acquire the necessary goods, and return to England. They could then distribute them locally at reasonable prices, helping the community survive. For this reason, it was said that no local court in Cornwall would convict these men—their smuggling was seen as a vital service, not a crime.

Below written again in his own words Harry Carter: Captured by the Revenue
recounts how he was detained as a prisoner on a Revenue Cutter for twelve weeks after being caught smuggling near The Mumbles, Swansea. Remarkably, he was later cleared of all charges, thanks to the intervention of his friends at home who appealed to the Lords of the Admiralty.

In January 1782, the Carter brothers’ ships were called into service by the Collector of Customs at St Ives. The ‘Phoenix’ (owned by the Carters and commanded by Davy) and the ‘Shaftesbury’ (commanded by Harry Carter), both operating as privateers, were asked to respond to attacks by the ‘Black Prince’, a privateer from Dunkirk.
Although they were known smugglers, they complied to avoid offending the Collector. The two ships sailed to St Ives and engaged the Black Prince, resulting in the sinking of the ‘Phoenix’. It seems remarkable today that men officially considered lawbreakers could be called upon by the authorities for such action.

With thanks to Kresen Kernow (Centre for Cornwall’s Historical Archives), we can see a list of Cornish privateersfrom 1777, recorded by the Revenue for ships licensed to carry guns.
Among the list are the Carter brothers’ vessels:
Both ships were massive compared to other privateers of the time. These licenses effectively allowed them to arm their vessels, demonstrating the high level of trust the Carter brothers enjoyed with the government.
An excerpt from The Autobiography of a Cornish Smuggler reveals how John Carter’s personality dominated the legends of Prussia Cove, to the extent that many of his associates were almost forgotten. Everything centred on him alone. It was John Carter who cut the harbours and the road, who adapted the caves, and who became the hero of countless tales from what locals later called the “good old days.”
One story in particular illustrates his character. During John Carter’s absence from home, excise officers from Penzancearrived by boat and seized a cargo that had recently arrived from France. The goods were taken to Penzance and secured in the Custom House stores.
When John Carter returned and learned what had happened, he faced a dilemma. He explained to his comrades that he had already agreed to deliver that cargo to his customers by a fixed date. His reputation as an honest man was at stake, and he was determined to keep his word.
That night, a group of armed men broke into the Custom House stores at Penzance. The “King of Prussia” reclaimed only what belonged to him, returning the cargo to the Cove without being discovered.
The following morning, when the officers found the store broken into and examined what had been taken, they reportedly said to one another that John Carter must have been responsible—because only the exact goods that belonged to him were missing. They knew he was an honest man who would not take anything that was not his own.
True to his word, John Carter delivered the smuggled goods to his customers as promised.
With kind permission of Kresen Kernow (Centre for Cornwall’s Historical Archives), the list below shows Cornish privateers in 1777, compiled by the Revenue. This record details ships that were officially licensed to fit guns aboard their vessels.
Included on the list are ships owned and commanded by the Carter brothers:
Both ships were exceptionally large and heavily armed compared to most other privateers of the period. The issuing of such licences—effectively permission to arm their ships—demonstrates the level of trust placed in the Carter brothers by the government of the day.


Along the Cornish coast in the late eighteenth century, the line between outlaw and hero was often blurred. Few men embodied this more than Harry Carter of Pengersick.
Though known as a smuggler, Harry was also a seasoned sailor and trusted privateer. So trusted, in fact, that in January 1782 the Collector of the Port at St Ives turned to him for help. A large French vessel was causing concern offshore, and the authorities needed someone who knew these waters—and the dangers of them—better than anyone.
Harry did not refuse. As he later wrote, he feared offending the Collector and sailed to St Ives with his ship to confront the threat. What followed was a fierce encounter. One of the Carter family vessels was lost, sunk in the action. Yet in the midst of that loss, Harry and his crew saved the lives of seventeen sailors.
It was a moment that captured the contradiction at the heart of Harry Carter’s life. Officially, he was a man who lived outside the law. In reality, he was repeatedly called upon by that same system when courage, seamanship, and resolve were required.
This was Cornwall in an age of hardship and war—a place where survival mattered more than rigid morality, and where men like Harry Carter were judged not by the letter of the law, but by their actions when it truly counted.

Below is a detailed explanation of a Port Collector.

The Carter brothers have been described by the BBC as “among the most famous of all the Cornish smugglers”, and by The Guardian as “Cornwall’s most famous free traders.” Their story was even echoed in popular culture, with smuggling scenes in the 1975 Poldark filmed at Prussia Cove itself.
Legend has it that the cove—formerly known as Portleigh—took its name from John Carter, the second eldest brother. As a boy in the 1740s, John idolised the King of Prussia, a powerful European figure of the age. He copied his style, marched his brothers into mock battles around the cove, and earned the nickname “The King of Prussia,” a name that would cling to the landscape long after his childhood games ended.
As an adult, John Carter appears to have been the quiet organiser—the managing mind behind the operation—keeping a deliberately low profile with officialdom. While legends about him abound, there are surprisingly few contemporary documents that name John directly as the “King” of Prussia Cove. Instead, official correspondence occasionally applies the title to his younger brothers, Henry (Harry) and Charles, likely reflecting the authorities’ uncertainty about who was who. What is beyond doubt, however, is this: the Carter brothers were a force to be reckoned with.
This website deals not in ghosts, pixies, or invented folklore. What you are reading here is documented history, supported by old maps, paintings, photographs, and books written at the time.
To understand their story, imagine Cornwall in the 1700s. There was no street lighting—only candles, torches, and oil lamps. When darkness fell, this coast belonged to those who knew it best. Places like Pengersick, whose name comes from the Cornish “penn kersyek” meaning “head of the marsh”, became natural havens. The land here was wet, reed-filled, and boggy, lying halfway between the Customs offices of Penzance and Helston—right at the edge of each officer’s patrol area.
The main turnpike road from Penzance stopped at Marazion. Beyond that lay rough cart tracks and bridle paths. Revenue officers—known as Riders—had to cross the vast Marazion reed marsh, the largest reed bed in Cornwall. In darkness, unfamiliar ground, and bad weather, the smugglers quite literally owned the night.
Contemporary accounts confirm just how remote this area was. In the mid-18th century, West Cornwall had almost no roads. The mother of Sir Humphry Davy recalled that there was only one cart in Penzance, with packhorses used everywhere else. Official town records even show resistance to extending the turnpike beyond Marazion, keeping places like Pengersick isolated and hard to reach.
Harry Carter’s autobiography, expanded with notes by John B. Cornish in 1900, describes Pengersick as a tiny hamlet of four or five cottages. Smugglers Barn was one of just three dwellings, alongside a meeting house and surrounding land. Nearby places mentioned in the autobiography—Rudgeon, Trevean, Caerlean, Kenneggey, and Rinsey—were no larger, each just a small cluster of cottages scattered across the landscape.
This was not a romantic wilderness. It was a hard, poor, half-civilised world. And in that world, the Carter brothers did not merely survive—they shaped the coastline, the coves, and the stories that still echo here today.

By 1784, the British government had reached the limit of its tolerance. An Act of Parliament, shown here, made the consequences of smuggling brutally clear.
Under this law, anyone found harbouring a smuggler faced seven years’ transportation, usually to penal colonies overseas. For smugglers themselves, the punishment was even harsher. If a smuggler failed to surrender when required, the penalty was death.
These laws, recorded here on the right, by His Majesty’s Stationery Office (see page 767), show just how seriously the authorities viewed smuggling—and how dangerous the Carter brothers’ world had become. What had once been a way for coastal communities to survive was now officially treated as a capital crime.
This stark legislation helps explain why the lives of men like the Carters were lived in constant tension, courage, and risk—and why their survival and reputation were all the more remarkable.

To understand just how early the Carter story begins, it helps to place it alongside better-known figures of the age. Dick Turpin was hanged in April 1739. At that moment, John Carter was just one year old, already living here in Pengersick.
As John grew, alongside his brothers Harry and Charles, the Carter family would go on to become the most notorious smugglers in Cornwall’s history—and remarkably, they would outlive almost every major smuggling gang in Britain.
Elsewhere, smuggling dynasties rose and fell quickly. The infamous Hawkhurst Gang of Kent, founded in 1735, collapsed within little more than a decade. Its leaders, Arthur Grey and Thomas Kingsmill, were executed in 1748 and 1749.
By contrast, the Carters endured. Through wars, changing laws, and increasingly brutal punishments, they survived where others did not—cementing their place as a uniquely long-lived and formidable force along the Cornish coast.
This concludes the story of the Carter Brothers

It is worth noting that Pengersick appears on almost every English map produced since the late 16th century, including maps created on the European continent. This long and consistent appearance in historic cartography underlines the importance of the hamlet—and helps explain why this small place became the setting for such an extraordinary story.
