In May 1757 Frederick the Great invaded Bohemia, smashed an Austrian army outside Prague and bottled it up inside the besieged city. The Empress Maria Theresa could not sit by and allow the second city of the Empire to be captured and Marshal Daun was despatched with 60,000 fresh troops to its relief. This volume details the actions that ensued when, characteristically aggressive, Frederick gathered all available men and marched to meet Daun whose infantry alone almost outnumbered Frederick. Undaunted, Frederick decided to try to turn the Austrian right flank. Marshal Daun saw through Frederick's manoeuvre and when the Prussian infantry attacked on 18th of June the Austrians were waiting.
