At 3 o’clock matters had,öniggrä consequently, changed very much for the worse with the Austrians. On the left, the Saxons had been driven from their position; on the right, the Prussian Guards and VIth Corps occupied the line Rosberitz-Nedelist-Lochenitz. The Austrian IVth and IId Corps had been defeated, and were retreating upon Wsestar, Sweti, Predmeritz and Lochenitz. The 1st Division of the Guards had captured 55 guns, and had seized the key of the Austrian position. The Austrian IIId Corps was sandwiched between the Guards and the First Army. Yet the position of the Guards was full of danger. In the valley of Sweti-Wsestar-Rosnitz were the two intact corps of Austrian reserves, with more than 70 squadrons of cavalry; and between Wsestar and Langenhof were massed the powerful batteries of the reserve artillery, which kept Rosberitz and Chlum under a heavy fire. The main body of the 2d Division of the Guards was just ascending the heights of Maslowed. There were no other troops within a mile and a quarter upon whom they could depend for assistance.
Von Benedek, who had taken his position between Lipa and Chlum, hearing of the occupation of the latter village by the Prussians, could scarcely believe the surprising news. As he rode hurriedly toward Chlum, the information was rudely corroborated by a volley from the Prussians, which mortally wounded an aide-de-camp, and seriously injured several other members of his escort. There was no longer any doubt. Victory was now out of the question, and it was necessary to take prompt measures to save the right wing from annihilation, and to prevent the retreat of the rest of the army from being cut off.
A brigade of the Austrian Ist Corps was sent to reinforce the Saxons near Problus, and another brigade of the same corps was sent against the Lipa wood and the heights west of Chlum. The latter brigade, reinforced by a brigade of the IIId Corps and fragments of the IVth Corps, made three desperate attacks upon the advanced-guard of the 2d Division and part of the 1st Division of the Prussian Guards at these points, only to recoil, completely baffled, before the deadly fire of the needle gun. The IIId Corps no longer had any intact troops; it was between two fires; it began its retreat, and abandoned the village of Lipa to the Prussians. On the left, the main body of the 1st Division of the Guards was engaged at Rosberitz with the Austrian VIth Corps. Advancing resolutely to the attack, the Austrians dislodged the Guards from the village after a bloody struggle; but as they halted at the outskirts of the town to re-form for another assault, the Guards were reinforced by the advanced-guard of the Ist Corps. At the same time, the commander of the Prussian VIth Corps, leaving the 12th Division engaged with the Austrians at Lochenitz, half-wheeled the 11th Division to the right, and advanced from Nedelist upon Rosberitz. The Austrian IId Corps was already in retreat. A counter-attack of the Guards and the Ist Corps drove the Austrians out of Rosberitz; and the 11th Division striking them on the flank routed them with heavy loss. The 11th Division then attacked a brigade of the Austrian IVth Corps, which had taken up a position near Sweti to protect the reserve artillery. The brigade and the artillery were driven back to the village, which was carried by assault, many cannon being captured. The Vth Corps reached Horenowes at 4 o’clock, and was designated as the general reserve of the army.
