Jean Marie Antoine Philippe de Collaert (13 June 1761 – 17 June 1816) led the Dutch-Belgian cavalry division at the Battle of Waterloo. He became an officer in the Habsburg Austrian cavalry in 1778 and later served in the Dutch Republic army until 1786. After the armies of the First French Republic overran the Dutch Republic in 1795, Collaert became a lieutenant colonel of hussars in the new army of the Batavian Republic, a French satellite state. He fought with distinction at the Battle of Castricum in 1799 and was badly wounded fighting the Austrians in 1800. He was promoted colonel in 1803. Under the Kingdom of Holland he became a major general in 1806 and colonel-general of the King's Bodyguard in 1808.
