The Dutch Raid on the Medway

Why does the Dutch Raid on the Medway matter?

Consider this: in June 1667, the most powerful warship in England — the Royal Charles, flagship of the Royal Navy — was dragged out of its moorings by Dutch sailors and towed across the North Sea to the Netherlands, where it was put on public display. Samuel Pepys, the naval official and diarist who recorded the attack in his diary, wrote that he feared "the whole kingdom is undone." What had gone so badly wrong that the greatest naval power in the region could have its flagship stolen? And what does this disaster tell us about the government that let it happen?

The Dutch Raid on the Medway — known in Dutch as the Tocht naar Chatham (the Voyage to Chatham) — took place between 9 and 14 June 1667 in the River Medway at Chatham, Kent. It was the culmination of the Second Anglo-Dutch War (1665-1667), a conflict fought over trade routes, colonial possessions, and maritime dominance. The attack was planned and led by Admiral Michiel de Ruyter, one of the greatest naval commanders of the seventeenth century.

For the AQA 2027 GCSE History exam, the Dutch Raid on the Medway is the historic environment site for Restoration England. The "site" encompasses the River Medway itself, the naval dockyards at Chatham, and the scene of the raid that shocked the Restoration court. Examiners will ask about the causes of the raid, the events of the attack, and what it reveals about the state of Restoration government. This page prepares you for those questions.

The background: the Second Anglo-Dutch War

England and the Dutch Republic were commercial rivals. Both were maritime powers competing for trade routes, fishing grounds, and colonial territories in Asia, Africa, and the Americas. The First Anglo-Dutch War (1652-1654) had ended inconclusively. Hostilities resumed in the Second Anglo-Dutch War, which began in 1665 when English naval forces attacked a Dutch convoy.

Initially, the war went well for England. The English fleet won a significant victory at the Battle of Lowestoft in June 1665. But the war was expensive, and Charles II's government was struggling financially. Then came 1666 — a year of catastrophe for England regardless of the Dutch.

In September 1665, the Great Plague had killed an estimated 100,000 people in London alone. Then, in September 1666, the Great Fire of London destroyed approximately 13,000 houses and 87 churches, including the medieval St Paul's Cathedral. The cost of rebuilding, combined with the cost of the war, left the English government in severe financial difficulty.

Charles II made a fatal decision. In the spring of 1667, with negotiations for peace underway at Breda in the Netherlands, he decided to save money by laying up the English battle fleet — bringing the great warships into harbour and dismissing their crews, instead of maintaining them at sea. Sailors were paid off with promissory notes (IOUs from the Treasury) rather than cash, because the Treasury was nearly empty.

The attack: June 1667

The Dutch knew about the state of the English fleet. De Ruyter had been watching and waiting. In early June 1667, he sailed a fleet of approximately 60 warships and supporting vessels into the Thames Estuary.

9 June: Dutch forces attacked and captured Sheerness, a fort at the mouth of the Medway. This gave them control of the estuary.

12 June: The main attack. The River Medway was protected by a defensive chain — a massive iron chain strung across the river at Gillingham, supported by guard ships and shore batteries. The chain was intended to prevent enemy vessels from reaching the naval dockyard at Chatham and the fleet anchored there.

The Dutch broke through the chain. A Dutch frigate — the Pro Patria — rammed it repeatedly until it gave way. Dutch fireships followed, setting fire to the English warships moored in the river. Three major English warships — the Royal Oak, the Loyal London, and the Royal James — were burned. The noise of the cannon, the fires, and the chaos were visible and audible from London.

Then came the most humiliating moment: Dutch sailors boarded the Royal Charles — the largest ship in the English fleet, and the vessel that had carried Charles II home from exile to England in 1660 — cut its cables, and towed it out of the Medway and across the North Sea to the Netherlands. It was a trophy of extraordinary symbolic significance.

The response: Pepys, panic, and peace

The raid caused panic in London. Samuel Pepys, who worked at the Navy Board and kept a detailed diary of the period, recorded his horror — and his practical response, which was to bury his gold in his garden and send his wife and father out of London for safety.

Pepys also spent the following days working exhaustively to organise defences, supplies, and ships, and his diary is one of the most important primary sources for understanding what the English government actually knew and did during the crisis. His accounts of officials fleeing, of supplies not arriving, of administrative chaos, paint a damning picture of the Restoration government's capacity in an emergency.

The Treaty of Breda was signed on 31 July 1667, ending the Second Anglo-Dutch War. The terms were more favourable to the Dutch than the earlier English military successes had suggested they would be. England retained New Amsterdam (renamed New York after the Duke of York) — which it had seized from the Dutch in 1664 — but the overall settlement reflected the damage done by the Medway raid to England's negotiating position.

What does the Medway raid tell us about Restoration England?

The financial weakness of the Restoration government. The raid was made possible by Charles II's decision to lay up the fleet to save money. That decision arose from a genuine financial crisis — the cost of two years of war, combined with the costs of rebuilding after the Great Fire, had exhausted the Treasury. The Restoration government never solved its chronic shortage of money, which limited what it could do militarily and diplomatically throughout Charles's reign.

The administrative failures of the Restoration state. Pepys's diary makes clear that the English response to the raid was chaotic — slow, disorganised, and hampered by officials who were more concerned with their own safety than their duties. The contrast with the Dutch operation, which was carefully planned and executed with precision, is striking. The raid exposed systemic weaknesses in how England managed its navy and its national security.

The vulnerability of naval power to political decisions. England's fleet was the foundation of its security and its commercial power. The decision to lay it up for financial reasons was a gamble that the peace negotiations at Breda would succeed before the Dutch could act. The Dutch called that bluff. The lesson — that naval power requires continuous maintenance and investment — was one that England took seriously in the decades that followed.

Return to the question at the start: what had gone so badly wrong? The answer is not simply military — it is political, financial, and administrative. The Dutch Raid on the Medway was a catastrophe made possible by a government that could not pay its sailors, could not maintain its defences, and was outmanoeuvred by an enemy that understood exactly how to exploit those weaknesses. Samuel Pepys feared "the whole kingdom is undone." It wasn't — but it was humiliated. And the humiliation mattered.
