Gradually, therefore, the war spirit revived in France. No one remonstrated when once more recourse was had to the fatal policy of anticipating the annual conscription. Not only were the conscripts for 1810 called out, but the number was stretched to the utmost, and those who from immaturity or other causes had been unavailable in 1806, 1807, 1808, and 1809 were now collected. The total of the youths thus swept together was not less than a hundred and sixty thousand. To render available their slender efficiency, they were divided among the various regiments already in the field, in each of which these raw and boyish recruits constituted a fifth battalion. Since the Archduke Charles had been again at the helm of military affairs in Austria, not only had a transformation been wrought in the army as a fighting instrument, but the general staff had likewise been completely reorganized. For two years, therefore, Austria's occupation had been not only forging a sword, but practising, as well, the wielding of it. The lessons taught her by previous experience in Napoleonic warfare were thoroughly learned. It was consequently a very different strategic problem which the Emperor of the French had to solve in this campaign. For two years the Archduke had been studying his task, and that in the light of ample experience. The conclusion he reached was that he would attack and overpower Davout in Saxony; then, by an appeal to their German patriotism, raise and use the peoples of northern and central Germany for an overwhelming assault on Napoleon. But as the time for action grew near, the moral influence of those annihilating blows which the French armies had struck once and again began to assert itself and to create hesitancy. Count Stadion, the minister of state, knew that diplomacy had reached the limit of its powers and could gain at most only a few weeks. These he felt sure the enemy would use to better advantage in strengthening himself than Austria in her poverty could do. He was therefore urgent for prompt action. Charles, on the other hand, hesitated to face the miraculous resources of Napoleon without a finishing touch to some of his preparations which were still incomplete. He therefore began in January to procrastinate, and consequently it was not until February that Francis demanded an advance. In this interval the whole plan of campaign was changed. The main army, under Charles, was to be collected in Bohemia, ready for action in any direction, so as to thwart whatever course Napoleon might adopt. Hiller was to guard the line of the Inn, the Archduke Ferdinand was to march against Warsaw, while the Archduke John was to enter the Tyrol from Italy and excite the people to revolt. On April ninth all these movements were well under way; Hiller had reached the Inn, and Charles declared war.
