 Although the Dutch King William I rejected this suggestion at first, after the stand-off had dragged on for several years, he gave way, and agreed to partition in 1839.In the Third Partition, Luxembourg lost all of its western territories, including the towns of Arlon, Aubange, Bastogne, Durbuy, Marche-en-Famenne, Neufchâteau, and Virton.They (along with the Duchy of Bouillon) later formed the Belgian Luxembourg province, which is now a Walloon province, the largest in Belgium.
