Thanks to this password, all the troops had been concentrated by midnight, and the march was just about to begin when another courier arrived from the generalissimo, and informed the archduke that the enemy was advancing, and that it was now the generalissimo's intention to attack him and force him to give battle. The Archduke John was ordered to march as rapidly as possible to Siebenbrunn, whither a strong corps of the enemy had set out. The Archduke John now advanced with his ten thousand men with the utmost rapidity toward Marchegg. The troops were exhausted by the toils and fatigues of the last days; they had not eaten any thing for twenty-four hours; but the archduke and his generals and staff- officers always knew how to stir them up and induce them to continue their march with unflagging energy. Thus they at length reached Marchegg, where they were to rest for three hours. But no sooner had they arrived there than Count Reuss, the generalissimo's aide-de-camp, galloped up on a charger covered all over with foam. The count had ridden in seven hours from Wagram to Marchegg for it was all-important that the archduke should accelerate his march. The battle was raging already with great fury. The generalissimo was in urgent need of the archduke's assistance. Hence, the latter was not to rest with his troops at Marchegg, but continue his march and advance with the utmost speed by Siebenbrunn to Loibersdorf. At Siebenbrunn he would find Field-Marshal Rosenberg; he should then, jointly with him, attack the enemy. "Let us set out, then, for Loibersdorf," said John, sighing; "we will do all we can, and thus avoid being charged with tardiness. Up, up, my braves! The fatherland calls us; we must obey it!" But the soldiers obeyed this order only with low murmurs, and many remained at Marchegg, exhausted to death. The troops continued their march with restless speed, and mute resignation. The archduke's face was pale, his flashing eyes were constantly prying into the distance, his breast was panting, his heart was filled with indescribable anxiety, and he exhorted his troops incessantly to accelerate their steps. Now they heard the dull roar of artillery at a distance; and the farther they advanced, the louder and more terrific resounded the cannon. The battle, therefore, was going on, and the utmost rapidity was necessary on their part. Forward, therefore, forward! At five o'clock in the afternoon they at last reached Siebenbrunn. But where was Field- Marshal Rosenberg? What did it mean that the roar of artillery had almost entirely died away? And what dreadful signs surrounded the horizon on all sides? Tremendous clouds of smoke, burning villages everywhere, and added to them now the stillness of death, which was even more horrible after the booming of artillery which had shaken the earth up to this time. Where was Field-Marshal Rosenberg?
