La Haye, Lasne

La Haye was a farm, in a hamlet of the same name, in the Belgian municipality of Lasne. It was destroyed by fire in 1910. During the Battle of Waterloo (18 June 1815) the farm was one of the fortified garrisoned points that made up a bulwark on the extreme left (eastern end) of the Duke of Wellington's Anglo-allied line.

History
Along with La Haye, the eastern bulwark consisted of three other garrisoned and hastily fortified locations: less than 150 m to the west was Papelotte farm which like la Hay was on the northern bank of a shallow valley. About 430 m to the east was the hamlet of Smohain. At this point the valley had become a defile with a boggy stream at the bottom. The fourth location was the now ruined Châteaux Frischermont (then similar to the better known Châteaux Hougoumont which was located on the Anglo-allies right-hand flank ) which was about 700 m to the south-east on a premonitory on other bank of the valley.

The bulwark was held during the day by Anglo-allied soldiers under the command of Prince Bernhard of Saxe-Weimar. At about 19:30 the vanguard of Prussian I Corps (Zieten's) linked up with the Anglo-allied army in this area.
