Before the end of that dismal sixteenth century Flanders regained some of the liberties for which so much blood had been shed; but while the Protestant Dutch Republic rose in the north, the 'Catholic' or 'Spanish' Netherlands in the south remained in the possession of Spain until the marriage of Philip's daughter Isabella to the Archduke Albert, when these provinces were given as a marriage portion to the bride. This was in 1599. Though happier times followed under the moderate rule of Albert and Isabella, war continued to be the incessant scourge of Flanders, and during the marching and countermarching of armies across this battlefield of Europe, Ypres scarcely ever knew what peace meant. Four times besieged and four times taken by the French in the wars of Louis XIV., the town had no rest; and for miles all round it the fields were scarred by the new system of attacking strong places which Vauban had introduced into the art of war. Louis, accompanied by Schomberg and Luxembourg, was himself present at the siege of 1678; and Ypres, having been ceded to France by the Treaty of Nimeguen in that year, was afterwards strengthened by fortifications constructed from plans furnished by the great French engineer.[*] [Footnote *: Letter from Vauban to Louvois on the fortifications of Ypres, 1689; Vereecke, pp. 325-357.] In the year 1689 Vauban speaks of Ypres as a place 'formerly great, populous, and busy, but much reduced by the frequent sedition and revolts of its inhabitants, and by the great wars which it has endured.' And in this condition it has remained ever since. Though the period which followed the Treaty of Rastadt in 1714, when Flanders passed into the possession of the Emperor Charles VI., and became a part of the 'Austrian Netherlands,' was a period of considerable improvement, Ypres never recovered its position, not even during the peaceful reign of the Empress Maria Theresa. The revolution against Joseph II. disturbed everything, and in June, 1794, the town yielded, after a short siege, to the army of the French Republic. The name of Flanders disappeared from the map of Europe. The whole of Belgium was divided, like France, with which it was now incorporated, into _departements_, Ypres being in the Department of the Lys. For twenty years, during the wars of the Republic, the Consulate, and the Empire, though the conscription was a constant drain upon the youth of Flanders, who went away to leave their bones on foreign soil, nothing happened to disturb the quiet of the town, and the fortifications were falling into decay when the return of Napoleon from Elba set Europe in a blaze. During the Hundred Days guns and war material were hurried over from England, the old defences were restored, and new works constructed by the English engineers; but the Battle of Waterloo rendered these preparations unnecessary, and the military history of Ypres came to an end when the short-lived
