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 unmo-
lested by the enemy towards Meissen.
The news reached him that Glatz, one of the barrier for-
tresses of Silesia, had been taken by Loudon, and that the
latter was besieging Breslau. Daun had guessed the way l^
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 comv
paratively short distance apart. Although hampered by the
obstacles in their way and by a train of two thousand waggons,
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.
