have been accomplished in three months. The opposition on the march could not have been so severe as that which Stewart's desert column encountered. Nevertheless, as I have said, the Souakin-Berber route was pronounced impossible by the deciding authority. The comparative feebleness of contemporary warfare is perhaps exceptionally manifest in relation to the reduction of fortresses. During the Franco-German War the frequency of announcements of the fall of French fortresses used to be the subject of casual jeers. The jeers were misplaced. The French fortresses, labouring under every conceivable disadvantage, did not do themselves discredit. All of them were more or less obsolete. Excluding Metz and Paris, neither fortified to date, their average age was about a century and a half and few had been amended since their first construction. They were mostly garrisoned by inferior troops, often almost entirely by Mobiles. Only in one instance was there an effective director of the defence. That they uniformly enclosed towns whose civilian population had to endure bombardment, was an obvious hindrance to desperate resistance. Yet, setting aside Bitsch which was never taken, the average duration of the defence of the seventeen fortresses which made other than nominal resistance was forty-one days. Excluding Paris and Metz which virtually were intrenched camps, the average period of resistance was thirty-three days. The Germans used siege artillery in fourteen cases; although only on two instances, Belfort and Strasburg, were formal sieges undertaken. "It appears," writes Major Sydenham Clarke in his recent remarkable work on Fortification [Footnote: _Fortification_. By Major G. Sydenham Clarke, C.M. G. (London: John Murray).] which ought to revolutionise that art, "that the average period of resistance of the (nominally obsolete) French fortresses was the same as that of besieged fortresses of the Marlborough and Peninsular periods. Including Paris and Metz, the era of rifled weapons actually shows an increase of 20 per cent in the time-endurance of permanent fortifications. Granted that a mere measurement in days affords no absolute standard of comparison, the striking fact remains that in spite of every sort of disability the French fortresses, pitted against guns that were not dreamed of when they were built, acquitted themselves quite as well as the _chefs-d'oeuvre_ of the Vauban school in the days of their glory." Even in the cases of fortresses whose reduction was urgently needed since they interfered with the German communications--such as Strasburg, Toul, and Soissons--the quick _ultima ratio_ of assault was not resorted to by the Germans. And yet the Germans could not have failed to recognise that but for the fortresses they would have swept France clear of all organised bodies of troops within two months of the frontier battles. During the Peninsular War Wellington made twelve assaults on breached fortresses
