Cape Rachado, 1606: The Battle Both Sides Won

Eleven Dutch ships attacked a Portuguese armada off Malacca in August 1606 and lost the field after eight days. Within a generation the Strait belonged to the Company that lost the battle.

On 17 August 1606 eleven Dutch ships attacked a Portuguese armada in the Strait of Malacca. Eight days later the Dutch sailed away and the Portuguese Viceroy held the field. It is recorded here as a Portuguese victory, and it is also the moment the Portuguese position in the Strait began to fail.

The siege that came first

Malacca was the hinge of the eastern trade. Whoever held it controlled the narrow water through which the spice of the Moluccas, the silk of China and the cloth of Coromandel had to pass, and the Portuguese had held it since 1511.

In 1606 the Dutch admiral Cornelis Matelieff de Jonge laid siege to it in alliance with the ruler of Johor. Danvers puts the combined force at a hundred and fifty sail and sixteen thousand men, against a garrison of little more than a hundred Portuguese under André Furtado de Mendonça. The siege ran four months, and the besiegers are said to have thrown more than fifty thousand cannonballs into the city without making much impression on it.

What broke the siege was news rather than force. The Viceroy of the Estado da Índia, Dom Martim Afonso de Castro, had left Goa in May with twelve galleons, four galleys and some seventy other vessels, and he was on his way. Matelieff raised the siege and withdrew to meet him at sea.

Eight days off Cape Rachado

The Viceroy reached Malacca after a stormy passage in which some of his ships were lost. Shortly after his arrival, on 17 August, eleven Dutch vessels attacked him.

The first day's fighting lasted until dark with about equal loss on both sides. The next morning it resumed, and the balance began to tell: the Dutch ships were the larger and the more heavily armed, and they did considerable damage to the Portuguese. Vessels on both sides burned. The running fight went on, in Danvers's account, for eight days altogether, at the end of which the Portuguese ships were very much disabled.

Then, on 24 August, the Viceroy offered battle again — and the Dutch declined it and sailed away.

By the only test that a seventeenth-century commander would have recognised, that settles it. The side that offers battle and is not met has won the day, and the Viceroy entered Malacca with his fleet, where he found a city badly knocked about by the siege but still Portuguese.

What happened next, and why the verdict is not simple

The Viceroy then divided his fleet: seven galleons under Dom Álvaro de Meneses were sent towards the Nicobar Islands to meet the ships expected from Portugal, and five more under Nuno Álvares Pereira went to escort provision ships coming from Java through the Singapore Strait.

The Dutch, having refitted, learned that the armada had been split. On 22 October they came back to Malacca and fell on Pereira's five galleons alone.

That is the shape of the whole contest in miniature. The Portuguese could win an engagement and still lose the sea, because their strength was a single fleet that had to be everywhere, and the Company's strength was a permanent presence that could wait, repair and return. Within a generation the Dutch held the approaches; in 1641 Malacca itself fell to them.

Why the row says "Portuguese tactical victory"

Our record of Dutch Golden Age sea battles enters this action as a Portuguese tactical victory with medium certainty, and the certainty rating is doing real work.

The facts are not much disputed: the dates, the eleven Dutch ships, the eight days, the withdrawal. What is disputed is the scoring. The Dutch tradition has always read Cape Rachado as a strategic success — the blockade was resumed within weeks, the Portuguese fleet was damaged beyond quick repair, and the campaign that mattered was the one for the Strait rather than the one for that week. The Portuguese tradition reads it as a relief expedition that did exactly what it set out to do.

Both readings are supportable from the same sequence of events, which is precisely why the dataset carries an outcome column and a certainty column rather than one column pretending to be a fact.

The Asian half of the record

Cape Rachado is one of four Asian actions in the record, and the reason there are only four is worth stating. The wars of the Republic in Europe were fought between states that kept navies and printed accounts of them; the wars of the Company east of the Cape were fought by a chartered corporation whose records went into its own archives and stayed there.

The other three Asian rows come from Danvers's narrative of the Goa blockades: two engagements before the bar of Goa on 21 January and 11 February 1637, in which a Dutch squadron of ten vessels was met by a Portuguese fleet and the Portuguese claimed the advantage, and the destruction of a Portuguese fleet lying at anchor off Puludindin by seven Dutch ships in the same year.

Sources and further reading

The narrative here follows Danvers, The Portuguese in India, volume II, pages 136 and 137, which gives the siege, the eight-day battle and the division of the fleet in sequence. Matelieff's own journal, in Peter Borschberg's scholarly edition, is the indispensable Dutch account and the place to go for the admiral's reasoning; it is a modern scholarly edition and not openly available, which is why the dataset row cites Danvers for the page a reader can check.
