At 4 A.M. Dumoulin advanced on Pilgramshain, neglecting the fire of the Saxon outpost on the Spitzberg, whereupon this promptly retired in order to avoid being surrounded. Dumoulin then posted artillery on the slope of the hill and deployed his six grenadier battalions facing the village. The leading cavalry of the main army came up and deployed on Dumoulin's left front in open rolling ground. Meantime the duke of Weissenfels had improvised a line of defence, posting his infantry in the marshy ground and about Pilgramshain, and his cavalry, partly in front of Pilgramshain and partly on the intervening space, opposite that of the Prussians. But before the marshy ground was effectively occupied by the duke's infantry, his cavalry had been first shaken by the fire of Dumoulin's guns on the Spitzberg and a heavy battery that was brought up on to the Grabener Fuchsberg, and then charged by the Prussian right-wing cavalry, and in the melee the Allies were gradually driven in confusion off the battlefield. The cavalry battle was ended by 6.30 A.M., by which time Dumoulin's grenadiers, stiffened by the line regiment Anhalt (the "Old Dessauer's" own), were vigorously attacking the garden hedges and walls of Pilgramshain, and the Saxon and Austrian infantry in the marsh was being attacked by Prince Dietrich of Dessau with the right wing of the king's infantry. The line infantry of those days, however, did not work easily in bad ground, and the Saxons were steady and well drilled. After an hour's fight, well supported by the guns and continually reinforced as the rest of the army closed up, the prince expelled the enemy from the marsh, while Dumoulin drove the light troops out of Pilgramshain. By 7 A.M. the Saxons, forming the left wing of the allied army, were in full retreat.
