Frederick took 34,000 of his men to intercept Daun. Daun knew that the Prussian forces were too weak to both besiege Prague and keep him away from Prague for a longer time (or to fight the Austrian army reinforced by the Prague garrison), so his Austrian forces took defensive positions on hills near Kolín. Frederick was forced to attack the Austrians, who were waiting on the defensive with a force of 35,160 infantry, 18,630 cavalry and 154 guns. The battlefield of Kolín consisted of gently rolling hill slopes.
