By this time every one in London and Amsterdam was in a state of extreme suspense as to whether or not DeRuyter was on the Guinea coast. On the 14th of October, 1664, news was received both in Holland and in England from Cadiz to the effect that DeRuyter intended to sail to Guinea upon his departure from that port.[128] In Amsterdam, encouraged by this vigorous rumor, the stocks of the West India Company began to rise from the low point where they had been for some time.[129] When Downing chided DeWitt about DeRuyter, the latter replied in a bantering fashion that if he believed the report, notwithstanding what had been said to the contrary, to continue in the belief; it could do no harm.[130] In London, the apprehension of DeRuyter's expedition greatly checked the enthusiasm of the Royal Company, and caused the king to postpone Prince Rupert's departure to the African coast. VanGogh reported the cry that was heard everywhere in London, "Guinea is lost. What now is it possible to do with the Dutch."[131] The Dutch ambassador, who did not cease to haunt the king's chambers over Holmes' seizures, found Charles II irritable and greatly displeased with affairs. When questioned as to whether he would punish Holmes, the king declared that Holmes did not need to fear punishment at home since the Dutch had evidently sent forces to do it themselves.[132]

The news concerning DeRuyter's successful expedition to the African coast, which arrived in England just before Christmas, 1664, showed, as Pepys expressed it, that the English had been "beaten to dirt at Guinea."[133] Indeed DeRuyter's conquest of the coast in the end was as complete as that of Holmes.[134] With one exception DeRuyter captured all the English factories and forts, including Kormentine, which he delivered with their goods to the agents of the West India Company. The English retained only Cape Corse, which, because of its strong position and the loyalty of the natives, DeRuyter decided would offer a successful resistance.[135]

Up to the time that DeRuyter departed for the African coast it is conceivable that by mutual concessions the troublesome questions existing between England and the United Provinces might have been amicably settled. The Dutch, however, had decided that this could not be done with honor and advantage to themselves, and therefore they chose to answer the warlike actions of Holmes in kind. When the English learned of DeRuyter's activities on the African coast the growing animosity between the two countries was so greatly intensified that war was inevitable. The members of the Royal Company who realized the gravity of the situation begged the king to come to the company's assistance.[136] The king, who considered the company to be of great importance to the colonial trade, and who realized his own intimate connection with its formation, declared on January 2, 1665, that he was resolved "to assist, protect & preserve the said company in the prosecution of their said trade,"[137] a declaration which was tantamount to war.

The Anglo-Dutch war of 1665-7 was, therefore, as has long been known, a war over trade privileges. Furthermore, in the popular mind, it was the dispute over trading privileges on the West African coast which "became the Occasion, at least the Popular Pretence of the war with Holland."[138] In international disputes some facts, although of minor importance, are often seized upon with great vigor by the contending parties. It is very probable that both England and the United Provinces greatly overestimated the value of the African forts and factories, but, at that time, the possession of them seemed very important. To many of these places plausible claims were advanced by both the English and the Dutch. There was plenty of opportunity therefore for disputes, and the representatives of the two great commercial companies did not fail to utilize it.

If the factors of the two companies in Guinea found it impossible to reconcile their differences, the same observation may be made concerning Downing and DeWitt at The Hague. One is not inclined to excuse the deceit of the latter nor to sympathize with the apathetic neglect with which he met all English claims. On the other hand, Downing was perhaps the match for DeWitt in cunning and his master in argument. His contempt for the Dutch made it impossible for him to deal with them without gaining a complete victory. Compromise is the basis of most diplomacy, but such a word was scarcely in Downing's vocabulary. There were men in England who realized that Downing was slowly but surely leading the two countries into war. Clarendon reproved him for overzealousness; and Lord Hollis, the English ambassador in France, informed him that he saw no "causam belli, onely litigandi," and asked him if he could not temper his speech "by pouring in oyle & not vinegar," and thus prevent a war if possible.[139] In Downing's behalf it may be said, however, that his attitude was the same as that of the mercantile interests in England which he so well represented. The increasing importance of the mercantile element, both in England and Holland, and their desire to encroach on the trade of one another in all parts of the world, especially in Guinea, was responsible for the war.[140] When the war was inevitable, representatives of the English commercial interests assured the government of their loyal support and assistance.[141] As for the Dutch they, too, entered the conflict with high hopes for they did not fear Charles II as they had feared Cromwell.

Sir Robert Holmes who had been so largely responsible for the difficulties which resulted in the Anglo-Dutch war arrived in England early in January, 1665. He was ordered to surrender the ships which he had taken from the Dutch in Guinea to the Royal Company.[142] On the 9th of January, by way of appeasing VanGogh, he was thrown into the Tower of London,[143] where he was to remain, the king declared, until he gave a satisfactory account of his actions at Cape Verde. Once more it appeared as if proceedings were to be taken against him "according to the exigency of the case."[144] It is interesting to note that his imprisonment resulted from the capture of the one place, mention of which was omitted in his instructions. However, Holmes was not long detained in confinement. Probably on account of the influence of the duke of York and of Prince Rupert he was again set at liberty toward the last of January,[145] and VanGogh reported that he was even enjoying royal favor.[146] Apparently Holmes was unable to render a satisfactory account of his prizes to the Royal Company, however, and he was therefore reconfined in the Tower about the 24th of February.[147] On the third of March he was examined before the Privy Council in regard to his expedition. His explanation of the various events was found satisfactory and he was forthwith ordered to be discharged from the Tower.[148] This order was not executed at once because he had not even yet rendered a satisfactory account to the Company.[149] Royal clemency was invoked and a warrant was issued March 23, 1665, releasing him from all criminal and pecuniary charges which might be brought against him.[150] The king's intervention in his behalf brought to an end the connection of Sir Robert Holmes with the company's affairs on the African coast.

By concluding the account of the diplomatic relations of England and the United Provinces with the early part of 1665, it is not intended to convey the idea that all diplomatic intercourse between the two countries ceased at that time. Downing remained in The Hague until August of that year, but neither side thought seriously of attempting to prevent the struggle in which they were already engaged on the African coast. DeRuyter arrived at Cape Verde on October 11, 1664, where he found nine English vessels most of which were in the service of the Royal Company and had only recently arrived on the Guinea coast. In response to an inquiry made by the English as to his intentions DeRuyter replied that he had come to punish the Royal Company for Holmes' hostile actions. He demanded the surrender of the company's factors and goods on shore and on the several ships. Since the English were unable to resist they surrendered the goods of the Royal Company after which the vessels were permitted to depart. In this way DeRuyter attempted to show plainly that he was not carrying on hostilities against the English nation, but was only aiding the West India Company to recover its property and goods, and to punish the Royal Company for the actions of Sir Robert Holmes.

DeRuyter left a Dutch garrison at Cape Verde and started with his plunder for Elmina. On the way he despoiled the English factory on the Sierra Leone River. On December 25 he arrived on the Gold Coast and made an attack on Tacorary where he was temporarily repulsed, but later he succeeded in blowing up this English factory. He then proceeded to unload at Elmina the effects which he had taken from the English. While doing so he received orders from the States General, dated October 21, 1664, commanding him to seize all English goods and vessels, whether they belonged to the Royal Company or not. In accordance with these instructions DeRuyter captured several English vessels, but he considered his chief duty to be the taking of the English fort at Kormentine. An agreement was made with the natives of the neighboring region of Fetu, who acted in conjunction with the Dutch ships and with the forces which DeRuyter landed. Although many of the natives remained loyal to the English, Kormentine fell an easy prey to the attacking party about the first of February, 1665. The other English factories, with the exception of Cape Corse, were also occupied without much difficulty. Although DeRuyter had received special orders to reduce Cape Corse, he considered this impossible, on account of the ease with which it could be defended and the loyalty of the Negroes to the English cause in that territory. DeRuyter was therefore compelled to depart from the Gold Coast on his voyage to Barbadoes without having taken possession of Cape Corse[151].

On April 18, 1667, Lord Hollis and Sir William Coventry, who were selected as the English envoys to treat for peace between England and the United Provinces, were instructed to propose that each country retain whatever places were in its possession on the 25th of the previous December. On the other hand, the English were also directed to induce the Dutch to give back Kormentine if possible[152]. How vigorously the envoys urged the return of Kormentine cannot be ascertained, but at any rate they were unsuccessful in obtaining it. When the treaty was concluded at Breda, July 21, 1667, it provided that each country should retain the territories which it held on the tenth of the previous May[153]. Thus ended the war which had in so large a measure been caused by the troubles between the Royal Adventurers and the West India Company.

At the conclusion of peace between the two countries, the English cannot be said to have been in a better position on the Guinea coast than they were before the war. On the other hand, it would not be difficult to rebuild new factories at the places which they had lost during the war. Indeed at the time peace was made factories had already been settled in several places occupied before DeRuyter's expedition. Nicolas Villaut, a Frenchman who made a voyage down the coast of Guinea in the years 1666 and 1667 mentioned an English factory on one of the islands in the Sierra Leone River, another at Madra Bomba just north of Cape Mount, and still another just below Cape Miserado[154]. He also mentioned the strength of the English fortress at Cape Corse, and declared that, although there was war in Europe between England and Denmark, the English factors at Cape Corse and those of the Danes at the neighboring fort of Fredericksburg made an amicable agreement to commit no acts of hostility against one another; and that this agreement was so punctually observed that the soldiers of the two nations mingled freely at all times[155]. Villaut failed to describe the condition of the company's fort in the Gambia River, but on October 30, 1667, an attack on it by the natives was reported to the general court of the company[156]. The Negroes succeeded in obtaining possession of the island but were presently dislodged by the company's factors after the loss of a number of white men[157].
