Note 684 — Chapter VII
Reading edition
The absurd and highly blamable conduct of Buckingham has created a prejudice in favour of the court of Madrid. That they desired the marriage is easy to be believed; but that they would have ever sincerely co-operated for the restoration of the Palatinate, or even withdrawn the Spanish troops from it, is neither rendered probable by the general policy of that government, nor by the conduct it pursued in the negotiation. Compare Hardwicke State Papers, vol. i.; Cabala, 1, et post; Howell's Letters; Clarendon State Papers, vol. i. ad initium, especially p. 13.
A very curious paper in the latter collection (p. 14) may be thought, perhaps, to throw light on Buckingham's projects, and account in some measure for his sudden enmity to Spain. During his residence at Madrid in 1623, a secretary who had been dissatisfied with the court revealed to him a pretended secret discovery of gold mines in a part of America, and suggested that they might be easily possessed by any association that could command seven or eight hundred men; and that after having made such a settlement, it would be easy to take the Spanish flotilla, and attempt the conquest of Jamaica and St. Domingo. This made so great an impression on the mind of Buckingham, that, long afterwards in 1628, he entered into a contract with Gustavus Adolphus, who bound himself to defend him against all opposers in the possession of these mines, as an absolute prince and sovereign, on condition of receiving one-tenth of the profits; promising especially his aid against any puritans who might attack him from Barbadoes or elsewhere, and to furnish him with four thousand men and six ships of war, to be paid out of the revenue of the mines.
This is a very strange document, if genuine. It seems to show that Buckingham, aware of his unpopularity in England, and that sooner or later he must fall, and led away, as so many were, by the expectation of immense wealth in America, had contrived this arrangement, which was probably intended to take place only in the event of his banishment from England. The share that Gustavus appears to have taken in so wild a plan is rather extraordinary, and may expose the whole to some suspicion. It is not clear how this came among the Clarendon papers; but the indorsement runs: "Presented, and the design attempted and in some measure attained by Cromwell, anno 1652." I should conjecture therefore that some spy of the king's procured the copy from Cromwell's papers.
I have since found that Harte had seen a sketch of this treaty, but he does not tell us by what means. Hist. Gust. Adolph. i. 130. But that prince, in 1627, laid before the diet of Sweden a plan for establishing a commerce with the West Indies; for which sums of money were subscribed. Id. 143.
