Austerlitz He became proprietor of the
Kollowrat Infantry Regiment # 36 in 1801. In the same year, he became a member of the
Aulic Council. He led the 25,400 Austrians of the 4th column at the
Battle of Austerlitz in 1805. Advancing across the Pratzen plateau, his force found itself in the path of Napoleon's main attack. After severe fighting,
Marshal Nicolas Soult's corps broke Kollowrat's Austrians and drove them off the field.
Danube campaign In 1809, Kollowrat led the II Corps during the
Battle of Eckmühl where it was unengaged because it operated north of the Danube. Transferring to command of the III Corps, his troops missed the
Battle of Aspern-Essling. Instead, he operated against Emperor
Napoleon's lines of communication with little effect. On the second day of the
Battle of Wagram,
Archduke Charles launched the corps of Kollowrat and
Johann von Klenau in a dangerous assault against the French left flank. Napoleon stopped the slow-moving III Corps by hurling a cavalry division at it. The French horsemen suffered crippling losses but they bought time for the Grand Army's artillerists to assemble a 112-gun grand battery. When these cannons opened fire, they stopped the III Corps cold. Next, Napoleon sent
Étienne Macdonald's corps against the junction between Kollowrat's III Corps and Johann Liechtenstein's I Reserve Corps. Despite this heavy attack, the Austrians succeeded in halting Macdonald. But by this time, the French had overwhelmed the Austrian army on the rest of the battlefield. Archduke Charles issued orders to retreat and Kollowrat was forced to pull back his command.
Later career After 1809, Kollowrat held no further major field commands. He was promoted to
Feldmarschall on 12 September 1809. In 1813 he fell ill and did not participate in the fighting. Instead, he organized relief efforts for the many Allied and French wounded soldiers. He died in Prague on 5 June 1816. ==References==
