Von Benedek discovering that these two corps had not taken up their designated positions, sent orders, before 11 o’clock, to their commanders, to fall back to the positions originally assigned to them. Unfortunately, the commander of the IVth Corps, ignorant of the approach of the Crown Prince, and flushed with his success against Von Fransecky, thought it an opportune moment to assume a vigorous offensive against the Prussian left, and would not make the movement ordered until he had sent a report to that effect to his chief. The projected offensive was disapproved, and the former order was repeated. The two corps now retired to the positions originally designated, the movement being covered by the fire of 64 pieces of artillery posted on the plateau of Nedelist. The withdrawal had been delayed too long; for the Crown Prince already had 48 guns in position between Racitz and Horenowes, the Prussian infantry was advancing, and the Austrian movement partook, consequently, of the nature of a retreat. Yet it is greatly to the credit of the Austrian troops that they were able to execute a flank movement--and a retrograde movement, too--under the fire of the enemy; though they had been in action fully three hours. At noon Von Benedek received a telegram from Salney, _via_ Josephstadt, announcing the approach of the Second Army. At this very moment the guns of the Crown Prince were playing upon the Austrian right flank. The advanced-guard of the 1st Division of Guards had debouched from Zizilowes at 11:15 A. M.; its right flank being covered by the cavalry brigade which had covered the left of the 7th Division. The advanced-guard of the 2d Guard Division, (which had been separated from the main body by the Reserve Artillery of the 1st Division cutting into the column on the road) without waiting for the arrival of its comrades, joined the 1st Division in its attack upon Horenowes. At noon the 12th Division had captured the Horicka Berg, the 11th Division had driven the Austrians from Racitz, and the Guards were advancing upon Horenowes. The withdrawal of the Austrian IId Corps had been covered by 40 guns posted east of Horenowes, which kept up a heavy fire upon the Prussians. But the Guards easily carried Horenowes, the position of the great battery was turned, the hostile infantry was advancing upon its flank, and the artillery was forced to retire. The 12th Division, in the meantime, had captured Sendrasitz, cutting off the Austrian brigade which had been covering the right flank. The 11th Division then moved up to a position north of Sendrasitz, on the left of the Guards, and the latter advanced to Maslowed. The Prussians now had 90 guns on the heights of Horenowes; and most of these pieces were hurried forward beyond Maslowed, within 1,300 paces of the Austrian position, where they prepared the way for the infantry assault by a vigorous cannonade.
