 The Army of the Meuse was based in Limburg while the Army of the Scheldt surrounded the still Dutch-held citadel of Antwerp, however the distance between the two forces was too great and each was effectively cut off.On the morning of 2 August 1831, just days after Leopold's coronation, the Dutch crossed the border near Poppel.Belgian scouts noticed the advance, and a number of roads were blocked with felled trees.
