During the interval of peace that preceded the
Seven Years' War he was engaged in carrying out an elaborate scheme for the reorganization of the Austrian army, and it was chiefly through his efforts that the
Theresian Military Academy was established at
Wiener-Neustadt in 1751. When a
Third Silesian War broke out, he was not actively employed in the first campaigns of the war, but in 1757 he was placed at the head of the army which was raised to relieve
Prague. On 18 June 1757 Daun decisively defeated Frederick for the first time in his career in the desperately fought
Battle of Kolin. In commemoration of this brilliant exploit, the Queen immediately instituted a military order bearing her name, and Daun was awarded the first Grand Cross of that order. The union of the relieving army with the forces of
Prince Charles Alexander of Lorraine at Prague reduced Daun to the position of second in command, and in that capacity he took part in the pursuit of the
Prussians and the victory of
Breslau. Frederick now reappeared and won the most brilliant victory of the age at
Leuthen. Daun was present on that field, but was not blamed for the disaster, and when Prince Charles resigned his command, Daun was appointed in his place. With the campaign of 1758 began the war of manoeuvre in which Daun, though missing some opportunities to crush the Prussians through over-caution, at least maintained a steady and cool resistance to the fiery strategy of Frederick. In 1758 Major-General
Ernst Gideon von Laudon, acting under Daun's instructions, forced the King to raise the
siege of Olmütz (
Battle of Domstadtl), and later in the same year Daun himself surprised Frederick at the
Battle of Hochkirch and inflicted a severe defeat upon him (14 October). Despite the tactical success and capture of many munitions and supplies that Daun achieved at Hochkirch, his failure to pursue Frederick through the densely wooded area allowed the Prussians to block his path into Silesia, meaning that his victory counted for little. In the following year the war of manoeuvre continued, and on 20 and 21 November he surrounded the entire corps of General
Friedrich August von Finck at
Maxen, forcing the Prussians to surrender. These successes were counterbalanced in the following year by the defeat of Laudon at
Liegnitz, which was attributed partly to the dilatoriness of Daun, and Daun's own subsequent defeat by
Hans Joachim von Zieten's bold attack in the great
Battle of Torgau. In this engagement, Daun was so severely wounded that he had to return to Vienna to recuperate. However, Daun and his forces inflicted heavy casualties on the Prussians and were able to retreat in good order. ==Reception==
