The Duke of Bevern was posted with 20,000 men to watch him; and Frederick sat down, with all his force, to capture Prague.
The siege train was hurried up from Dresden, and on the 9th of May his batteries on the south side of the city, and those of Keith on the north, opened fire on the city.

For a month missiles were poured into the town.

Magazines were blown up, and terrible destruction done, but the garrison held out firmly.

At times they made sorties, but these were always driven in again, with much loss.

But 50,000 men behind fortifications, however weak, were not to be attacked.
