Every approach to the city was closely guarded, but it became at last evident that, as long as the provisions held out, Prague was not to be taken.
The cannonade became less incessant, and after a month almost died away; for Daun had by this time gathered a large army, and it was evident that another great battle would have to be fought.

If this was won by the Prussians, Prague would be forced to surrender.

If not, the city was saved.
It was not until the 12th of June that Daun, a cautious and careful general, in accordance with urgent orders from Vienna prepared to advance.

His force had now grown to 60,000; 40,000 of the garrison of Prague could be spared, to issue out to help him.

Frederick had under 70,000, and of these a great portion must remain to guard their siege works.
