In a military point of view, too, the alliance of France was most valuable to the contiguous Netherlands.  A few regiments of French troops, under the command of one of their experienced Marshals, could block up the Spaniards in the Walloon Provinces, effectually stop their operations against Ghent, Antwerp, and the other great cities of Flanders and Brabant, and, with the combined action of the United Provinces on the north, so surround and cripple the forces of Parma, as to reduce the power of Philip, after a few vigorous and well-concerted blows, to an absolute nullity in, the Low Countries.  As this result was of as vital importance to the real interests of France and of Europe, whether Protestant or Catholic, as it was to the Provinces, and as the French government had privately manifested a strong desire to oppose the progress of Spain towards universal empire, it was not surprising that the States General, not feeling capable of standing alone, should make their application to France.  This they had done with the knowledge and concurrence of the English government.  What lay upon the surface the Netherland statesmen saw and pondered well.  What lurked beneath, they surmised as shrewdly as they could, but it was impossible, with plummet and fathom-line ever in hand, to sound the way with perfect accuracy, where the quicksands were ever shifting, and the depth or shallowness of the course perpetually varying.  It was not easy to discover the intentions of a government which did not know its own intentions, and whose changing policy was controlled by so many hidden currents.

Moreover, as already indicated, the envoys and those whom they represented had not the same means of arriving at a result as are granted to us.  Thanks to the liberality of many modern governments of Europe, the archives where the state-secrets of the buried centuries have so long mouldered, are now open to the student of history.  To him who has patience and industry many mysteries are thus revealed, which no political sagacity or critical acumen could have divined.  He leans over the shoulder of Philip the Second at his writing-table, as the King spells patiently out, with cipher-key in hand, the most concealed hieroglyphics of Parma or Guise or Mendoza.  He reads the secret thoughts of “Fabius,”—­[The name usually assigned to Philip himself in the Paris-Simancas Correspondence.]—­as that cunctative Roman scrawls his marginal apostilles on each despatch; he pries into all the stratagems of Camillus, Hortensius, Mucius, Julius, Tullius, and the rest of those ancient heroes who lent their names to the diplomatic masqueraders of the 16th century; he enters the cabinet of the deeply-pondering Burghley, and takes from the most private drawer the memoranda which record that minister’s unutterable doubtings; he pulls from the dressing-gown folds of the stealthy, softly-gliding Walsingham the last secret which he has picked from the Emperor’s pigeon-holes, or the Pope’s pocket, and which,
