What we are here concerned with, however, is not the details of Oliver's foreign policy, but its conception as a whole. It is true that the existing position of affairs in Europe,--in which France and Spain were neutralising the forces of one another--was almost an invitation to the strong military and naval power of the Protectorate to extend its influence at the expense of one or other of the rivals; but, so far as this consideration may have played its part in bringing Oliver to a decision, it has left no traces in his recorded words. Obviously, when he undertook the negotiation with the Dutch, he had two courses before him, either to lay the foundations of a general peace, or to leave himself free to push military and naval enterprises in other directions. It was the latter course on which he resolved--a course which has gained him the admiration of a posterity prompt to recognise in Oliver the ruler who, having received from the Commonwealth an excellently organised army and navy, was the first to apply those potent instruments of conquest to the acquisition of over-sea dominion. What posterity has failed to observe is that this design was incompatible with his other design of settling the government of England on a constitutional basis. By his resolve to seek military employment for the magnificent force that he had welded together, and to find reasons for going to war with some nation or other, rather than be driven into war by the necessity of upholding the honour and interests of the country, Oliver was compelled to keep up a military and naval establishment which may not have been in excess of the taxable capacity of the nation; but which at all events imposed a burden much heavier than that to which Englishmen had been accustomed to submit. Before Parliament met, after many hesitations he had resolved to send out one fleet under Blake into the Mediterranean to enforce the release of English prisoners taken by the pirates of the Barbary coast, and another fleet under Penn to seize upon Hispaniola or some other West Indian island as a response to the refusal of Spain to allow English merchantmen to trade even with English colonies in the West Indies, as well as to various acts of violence already committed by Spanish officials in American waters.
