The naval Battle of the Downs took place on 21 October 1639 (New Style), during the Eighty Years' War, and was a decisive defeat of the Spanish, commanded by Admiral Antonio de Oquendo, by the United Provinces, commanded by Lieutenant-Admiral Maarten Tromp.


The entry (in 1635) of France in the Thirty Years War had blocked off the overland "Spanish Road" to Flanders. To support the Spanish army of Flanders of Cardinal-Infante Ferdinand, the Spanish navy had to ferry supplies by sea via Dunkirk, the last Spanish-controlled port on the North Sea coast. A Spanish fleet, under admiral Lope de Hoces y Córdova, had managed to make the trip to Dunkirk in 1636 and again in 1637, without being spotted by Dutch squadrons. In 1638, the French invaded Spain, and laid siege to Fuentarrabia. Lope de Hoces was hurriedly dispatched to rescue the city, but his fleet was destroyed by the French navy under Henri de Sourdis while it lay at anchor near Getaria. As the remainder of the Spanish navy was engaged on missions in the Mediterranean and Brazil, there were not enough ships left for an attempt to Dunkirk that year.

In the spring of 1639, the Count-Duke of Olivares ordered the construction and assembly of a new fleet at A Coruña for a new relief jaunt to Dunkirk. 29 warships were assembled in four squadrons, soon joined by an additional 22 warships (also in four squadrons) from the Spanish Mediterranean fleet. Twelve English transport ships also arrived, contracted to carry the Spanish army under the flag of English neutrality. Lope de Hoces was offered overall command, but he turned it down, as a result the command passed to Antonio de Oquendo, commander of the Mediterranean fleet. Oquendo was under instructions to assume a half-moon formation, to induce the Dutch into a boarding battle. The flagship was placed on the right wing (rather than the center), as that is where it was expected the Dutch firepower would come from. In a curious decision, ships of different squadrons were mixed through the formation, an attempt to ensure that the smaller ships would be supported by larger ones. The vanguard was to be composed of the seven-ship "Dunkirk squadron" commanded by Miguel de Horna, in light of their experience with the channel.

The Dutch States-General made their own preparations. From intelligence networks, the Dutch learned that the Spanish fleet might attempt to make for the anchorage known as The Downs, off the English coast, between Dover and Deal. There they could anchor under the protection of English neutrality, and ferry the army and supplies on smaller, fast boats across the English Channel to Dunkirk. The States-General ordered a fleet of 23 warships and some fireships, under the overall command of Maarten Tromp, into the channel to prevent this eventuality, while the rest of the Dutch fleet was still being prepared. Tromp was under instructions to watch for and, if necessary, harass and delay the Spanish fleet, but was forbidden from engaging them in battle until the rest of the Dutch fleet, some fifty vessels under Johan Evertsen, had been launched and joined them. Setting out, Tromp divided his fleet into three squadrons – one squadron of fifteen ships, under rear admiral Joost Banckert, was dispatched to a position above the Downs, in case the Spanish fleet had circumvented the British Isles and was coming from that side, a second squadron of six ships under Witte de With was put inside the English Channel, on patrol by the English coast, while Tromp himself took the remaining 12 ships to patrol the French side of the channel.

Opening phase

The Spanish fleet of 75 ships and 24,000 soldiers and sailors set out on 27 August from A Coruña (in another calculation, 51 galleons, with the troops carried aboard 7 pataches and 12 English transports; on the whole, an estimated 8,000 sailors and 8,000 troops). The fleet reached the mouth of the English Channel on September 11. On September 15, they learned from a passing English ship that a Dutch squadron was anchored near Calais. On the morning of September 16, the Spanish fleet spotted the 12-ship squadron of Maarten Tromp near the French coast. Tromp immediately dispatched one of his ships to warn Banckert, leaving him with only 11. De With's squadron were visible at a distance, but too late to reach Tromp. With odds of 57 against 11, Oquedo could have probably just made for Dunkirk directly, and there would be little Tromp could to do stop it. But Oquedo could not resist the chance to make battle with such favorable odds. Perhaps not realizing the size of the Spanish fleet, Tromp did not decline battle but rather ordered his squadron into a tight line of battle. Believing Tromp's squad was attempting to slip past his right wing, Oquendo impetuously ordered his flagship to turn hard starboard, hoping to board Tromp's flagship. This maneouver, however, was effected without warning the rest of the Spanish fleet. Some of the ships near Oquendo turned with him, others were confused and maintained bearing. The half-moon formation quickly disintegrated, and only the Dunkirk squadron and the galleon San Juan, kept up with the Spanish flagship's pursuit of Tromp. Had Oquendo given the order for a line, the immense Spanish fleet could have probably encircled and dispatched the Dutch squadron in a few hours. But Oquendo seemed intent on boarding the Dutch flagship. When he finally decided to turn for a shot, he did it too late and sailed past the Tromp's poop. Trying to correct his error, Oquendo decided to attempt to board the second ship in the Dutch column, the latter also avoided him. Oquendo's flagship and one of the Dunkirk ships, the Santiago, were now downwind and on the receiving end of the cannonades of the remaining nine ships of the Dutch column. Tromp turned his column and went for another round on the Santiago. Oquendo, the other six Dunkirk ships and the San Juan, unable to turn upwind, fired what they could. The artillery did little damage, but the Spanish musketry picked off many on the Dutch decks. This encounter lasted for three hours, in the course of which the Dutch ship Groot Christoffel accidentally exploded. By noon, the six ships of the De With column had reached Tromp, and increased his number to 16. Although the rest of the Spanish fleet remained dispersed and disorganized, many units had finally turned and were also approaching from the other side. For Tromp, this was building up into a dangerous situation, as the Spanish units upwind would cut off his exit, and force the Dutch squadron to turn into the shoals of the bay of Boulogne, and almost certainly run aground. But at this moment, Oquendo ordered the Spanish fleet to resume a half-moon formation. The Spanish ships turned, allowing Tromp's squadron to also turn, gain upwind, and escape the danger.

There were no more engagements that evening. The fleets anchored in, and the next day, rear-admiral Joost Banckert arrived, bringing the total Dutch fleet to thirty-two, but there was no engagement, just preparations for what was to become known as the Action of 18 September 1639. The Spanish, whose first priority was to protect the troops, not to endanger them by continuing the battle, were driven to take refuge off the coast of England, in the anchorage known as The Downs between Dover and Deal, near an English squadron commanded by Vice-Admiral John Pennington. They hoped the usual autumn storms would soon disperse the Dutch fleet. Tromp, as always, endured De With's insubordination with complacency. In a famous scene, described by De With himself, after the battle, he entered Tromp's cabin with his face sooty, his clothes torn, and limping from a leg wound. Tromp looked up from his desk and asked: "Are you alright, De With?" De With replied: "What do you think? Would I have been if you had come to help me?"

On the evening of the 28th, Tromp and De With withdrew to resupply, as they were short on gunpowder. They feared they had failed in their mission until they rediscovered the Spanish at the Downs on the 30th. Together, they blockaded the Spanish and sent urgently to the Netherlands for reinforcements. The five Dutch admiralties hired any large armed merchant ship they could find. Many joined voluntarily, hoping for a rich bounty. By the end of October, Tromp had 95 ships and 12 fire ships.

Meanwhile, the Spanish, who earlier had managed to sneak 13 or 14 Dunkirker frigates through the blockade, began to transport their troops and money to Flanders on British ships under an English flag. Tromp stopped this by searching the English vessels and detaining any Spanish troops he found. Uneasy about the possible English reaction to this, he pretended to Pennington to be worried by his secret orders from the States-General. He showed him, "confidentially", a missive commanding him to attack the Spanish armada wherever it might be located and to prevent by force of arms any interference by a third power. Legend also says that Tromp formally asked de Oquendo why he refused battle though he had superior firepower. De Oquendo replied that his fleet had to be repaired first, but that he could not obtain masts and other materials now that the Dutch blockaded him. On learning this, Tromp supplied the Spanish with the necessary materials for repair. Nevertheless they did not leave the English coast.

The battle

Before the Battle of the Downs by Reinier Nooms, circa 1639, depicting the Dutch blockade off the English coast, the vessel shown is the Aemilia, Tromp's flagship.

On 31 October, an easterly wind giving him the weather gage, Tromp having dispatched 30 ships under De With to watch the English and prevent them from interfering,[3] kept two squadrons to the north (under Cornelis Jol) and the south (under Commodore Jan Hendriksz de Nijs) to block escape routes and attacked with three squadrons. Some of the large, unmanoeuverable Spanish ships panicked on approach of the Dutch fleet and grounded themselves deliberately; they were immediately plundered by the English populace, present in great numbers to watch the uncommon spectacle. Others tried a planned breakthrough.

De Oquendo's Royal Flagship, the Santiago, came out first followed by the Santa Teresa, the Portuguese flagship. Five blazing fireships were sent into the Spanish ships. The first ship could disengage and avoid three of them in the last moment but these hit the following Santa Teresa, who had just managed to repel the attack of the other two. Too big (the biggest ship in the Spanish/Portuguese fleet) and slow to manoeuvre, and with no time to react, the Santa Teresa was finally grappled and set on fire by one fire ship. With Admiral Lope de Hoces already dead by his wounds, she fiercely burned with great loss of life.

The Portuguese ships were intercepted by the squadron of the Zeelandic Vice-Admiral Johan Evertsen who launched his fireships against them: most were taken or destroyed, leaving according to some reports 15,200 dead and 1,800 prisoner. The number of dead is today considered as greatly exaggerated; for example, it does not take into account that a third of the troops had already reached Flanders. De Oquendo managed to escape in the fog with about ten ships, most of them Dunkirkers, and reach Dunkirk. Nine of the ships driven ashore during the battle could be later refloated and also reached Dunkirk.[4]


According to the Spanish naval historian Cesáreo Fernández Duro, of the 38 ships that attempted to break the Dutch blockade, twelve ran aground on the Downs (of which nine were refloated and managed to reach Dunkirk), one was burnt by a Dutch fireship, nine surrendered (of which three were so damaged that they sank on the way to port) and 3 ran aground on the coasts of France or Flanders to avoid capture.[5]
The French diplomat Comte d'Estrades, in a letter to Cardinal Richelieu, claimed that the Spanish had lost thirteen ships burnt or sunk, sixteen captured with 4,000 prisoners, and fourteen lost off the coasts of France and Flanders,[6] a figure higher than the number of Spanish ships present at the Downs.[7] D'Estrades also reported in his letter that the Dutch had lost ten ships sunk or burnt.[6] This source is cited by Jean Le Clerc in his Histoire des Provinces-Unies des Pays-Bas.[8]
The Portuguese Admiral and historian Ignacio Costa Quintella gives figures of 43 ships and 6,000 men lost by the Spanish and some ships and more than 1,000 men by the Dutch.[9]
The Dutch sources only mention one Dutch ship lost that got entangled with the Santa Teresa and about a hundred persons dead. Historian M.G de Boer who did extensive research and published a book about the subject confirms this and puts Spanish losses in ships and men at about 40[1] and 7000[10] respectively.


The celebrated Dutch victory marked a significant moment in the shifting balance of naval power. Even if the Spanish mission was a failure, the larger part of the infantry troops managed to reach Flanders with all the money. Of the ships that succeeded in breaking through the blockade, many were severely damaged. Spain, straining under the vast commitments of the Thirty Years war, was in no position to rebuild its naval dominance.[11] Fighting over trade continued between Dutch and Dunkirker forces and the convoy itself was just one of a number; but these convoys paid a heavy price in lives and ships in running the Dutch blockades. These complicated operations in the Low Countries had left the overall Spanish Habsburg forces and finances in a precarious situation.[12] The Dutch, English and French were quick to take advantage by seizing some small Spanish island possessions in the Caribbean. But by far the worst effects for Spain were the increased difficulties it suffered in maintaining its position in the Southern Netherlands.

Tromp was hailed as a hero on his return and was rewarded with 10,000 guldens invoking the jealousy of De With who only got 1,000. De With wrote some anonymous pamphlets painting Tromp as avaricious and himself as the real hero of the battle. With Spain beginning to gradually lose its dominant naval position, England weak and France not yet in possession of a strong navy, the Dutch allowed their own to diminish greatly after the peace treaty was signed in 1648. So, with an ineffective naval administration, ships that were too light and too few in number, they were to find themselves at a serious disadvantage in their coming struggles with the English. However, they were able to maintain their large mercantile advantage over the English, entering into a period of increasing Dutch maritime superiority, both mercantile and naval, from the Second Anglo-Dutch War, until the onset of the 18th century.

The Battle of the Downs was a flagrant violation of English neutrality within sight of the English coast. For the English, their navy's inability to intervene was a humiliation. Lingering resentment from this incident may have influenced the breakout of the First Anglo-Dutch War, not far from the Downs at the Battle of Goodwin Sands in 1652.[citation needed]
