The wisdom of a foreign policy which gave England a land-frontier in Europe has been often discussed, and the conflict of argument has not yet died away. It is true that in later years this country has had forced on it the task of securing colonial possessions which, in some cases for thousands of miles, march with territories held by independent, and possibly hostile States. There is, however, no comparison between an enormous territory, such as the Dominion of Canada, inhabited by an increasing and loyal population, and a fortified post, such as that of Dunkirk, the inhabitants of which were alien in race and religion from the English garrison which was to hold them down, especially as Dunkirk was a mere port on the edge of a Continent held by great nations, two of which coveted its possession, and would certainly leave no stone unturned to recover it. The only parallels in our history worth considering are the occupation of Calais in the middle ages, and of Gibraltar in modern times. It is idle to speculate whether, if Dunkirk had not been surrendered amicably to France by Charles II., it would have undergone the fate of Calais, but it is not idle to remind ourselves that, whilst Gibraltar is occupied in order to keep the sea open, and has never been used as a threat to the independence of Spain, Dunkirk, as we know from Thurloe, to whom all the secrets of Oliver's mind were revealed, was occupied in the first place, as a menace to the Dutch maritime power, and in the second place, to enable England to interfere with effect against either France or Spain, whilst it was believed by Mazarin that Oliver's main object was to crush the growing power of France. These pretensions might be condemned or defended on abstract grounds, leaving out of account any particular circumstances or any particular time. What is absolutely certain is that such a policy, if it were to be successful, required not merely the prolongation of Oliver's life, but the continuation, and more than the continuation of his military system. At a time when the English nation--it matters not whether with just cause, or from mere impatience of a taxation which it was well able to bear--was bitterly complaining of the heavy burdens imposed by the necessity of keeping up the existing army, Oliver was embarking on a foreign policy which would topple down with a crash unless that army were doubled--perhaps even trebled--to make head against the enemies it would arouse. It was a policy condemned in advance if only by the desperate financial embarrassments which must follow in its train, when France was no longer bound to England by her need of help against Spain. The hostility of France might indeed be confronted by a Government strong in the devotion of its people, and in the accumulated wealth of another half-century of commerce--strong too in an alliance with military Powers, based on the need of joining in resistance to a common danger.
