"Just what I wished," the king said. "It has saved me a long march, and we will now go straight to Dresden."

The next day the army marched forward, circled round the western and southern sides of Dresden, and encamped at Gruna, a mile to the southeast of the city; and throughout the night laboured at getting up batteries. The division under Holstein was planted on an eminence on the other side of the river, across which a pontoon bridge was at once thrown. There was no fear of disturbance from Lacy, the united force of the enemy having retreated to the old Saxon camp at Pirna. The king, after seeing the batteries marked out, retired to bed early; and Fergus was able to ride round and pay a short visit to the count.

On the 14th the batteries opened fire--Maguire having refused the summons to surrender--and continued for four days without making much impression upon the walls, the heaviest guns being only twenty-five pounders.

On the 18th some heavy guns arrived from Magdeburg. The batteries were all ready for them, and as soon as they arrived they were set to work. Maguire burnt the suburbs outside the town, and answered the cannonade hotly.

Finding that the guns on the walls did but little damage to the Prussian batteries, Maguire mounted two or three guns on to the leads of the Protestant church, and from this commanding position he was able to throw shot right into them. The Prussian fire was at once concentrated on the church, which was speedily set on fire. This spread through the surrounding streets, and a tremendous conflagration raged for the next forty-eight hours. But by this time Daun, who had lost some days before setting out in pursuit of Frederick, was within five miles of the town, had driven Holstein across the river, and was in communication with Maguire.

On the night of the 21st-22nd Maguire's garrison, led by General Nugent, sallied out from Dresden; while four thousand of Daun's men marched round from the north side. For a time the assault on the Prussian intrenchments was successful, although Nugent was, on his first attack, repulsed and taken prisoner. But when Daun's people arrived the regiments defending the trenches were driven out. Then fresh battalions came up and drove the Austrians out, taking many prisoners.

Daun remained passive for some days after this, and Frederick continued to cannonade the city until the 29th; making, however, his preparations for departure, and going off unmolested by the enemy towards Meissen. The news reached him that Glatz, one of the barrier fortresses of Silesia, had been taken by Loudon, and that the latter was besieging Breslau.

Daun had guessed the way by which Frederick would retire, and had broken up the roads and bridges, and felled trees in the forests so as to render them impassable; and as soon as Frederick started he moved in the same direction, his position so serving him that, marching by a road parallel to that taken by the king, he was ahead of him. Lacy had been warned to be prepared, and he too started with his army, so that the three forces moved eastward at a comparatively short distance apart.

Although hampered by the obstacles in their way, and by a train of two thousand wagons, the Prussians moved rapidly and covered a hundred miles in five days. Daun made what was, for him, prodigious efforts also, and kept the lead he had gained.

On the 7th of August Frederick was thirty miles west of Liegnitz. Here he halted for a day, and on the 9th marched to the Katzbach valley, only to find that Daun was securely posted on the other side of the river, and Lacy on the hills a few miles off. The next morning Frederick marched down the bank of the Katzbach to Liegnitz, Daun keeping parallel with him on the other side of the river.
