But Henry's actions proclaimed louder than the words of himself (p. 068) or of others that he believed peace to be the first of English interests. He waged no wars on the continent except against France; and though he reigned thirty-eight years, his hostilities with France were compressed into as many months. The campaigns of 1512-13, Surrey's and Suffolk's inroads of 1522 and 1523, and Henry's invasion of 1544, represent the sum of his military operations outside Great Britain and Ireland. He acquired Tournay in 1513 and Boulogne in 1544, but the one was restored in five years for an indemnity, and the other was to be given back in eight for a similar consideration. These facts are in curious contrast with the high-sounding schemes of recovering the crown of France, which others were always suggesting to Henry, and which he, for merely conventional reasons, was in the habit of enunciating before going to war; and in view of the tenacity which Henry exhibited in other respects, and the readiness with which he relinquished his regal pretensions to France, it is difficult to believe that they were any real expression of settled policy. They were, indeed, impossible of achievement, and Henry saw the fact clearly enough.[147] Modern phenomena such as huge armies sweeping over Europe, and capitals from Berlin to Moscow, Paris to Madrid, falling before them, were quite beyond military science of the sixteenth century. Armies fought, as a rule, only in the five summer months; it was difficult enough to victual them for even that time; and lack of commissariat or transport crippled all the invasions of Scotland. Hertford sacked Edinburgh, (p. 069) but he went by sea. No other capital except Rome saw an invading army. Neither Henry nor Maximilian, Ferdinand nor Charles, ever penetrated more than a few miles into France, and French armies got no further into Spain, the Netherlands, or Germany. Machiavelli points out that the chief safeguard of France against the Spaniards was that the latter could not victual their army sufficiently to pass the Pyrenees.[148] If in Italy it was different, it was because Italy herself invited the invaders, and was mainly under foreign dominion. Henry knew that with the means at his disposal he could never conquer France; his claims to the crown were transparent conventions, and he was always ready for peace in return for the _status quo_ and a money indemnity, with a town or so for security. [Footnote 147: In 1520 he described his title "King of France" as a title given him by others which was "good for nothing" (_Ven. Cal._, iii., 45). Its value consisted in the pensions he received as a sort of commutation.] [Footnote 148: Machiavelli, _Opera_, iv., 139.]
