Jean Marie Antoine Philippe de Collaert (13 June 1761–17 June 1816) led the Dutch-Belgian cavalry division at the Battle of Waterloo. While a teenager, he participated in the War of the Bavarian Succession as an Austrian cavalryman. 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 Bergen and Castricum in 1799.
