The Waterloo Battlefield is located in the municipalities of Braine-l’Alleud and Lasne and Waterloo, about 15 kilometres (9.3 mi) south of Brussels, and about 2 kilometres (1.2 mi) from the town of Waterloo. The ordering of the places in the list is north to south and west to east.
- Sonian Forest—
50°46′0″N4°25′0″E—lies to the north of the battlefield on the approach to Brussels. Napoleon Bonaparte in Mémoires pour servir à l’histoire de France en 1815, avec le plan de la bataille de Mont-Saint-Jean repeatedly criticised the Duke of Wellington’s choice of battlefield because of the forest to his rear. For example on page 207 — “The position of Mont-Saint-Jean was ill-chosen. The first requisite of a field of battle, is, to have no defiles in its rear. The injudicious choice of his field of battle, rendered all retreat impossible”. This criticism has itself been criticised, with various explanation as to why Bonaparte was wrong.
- Waterloo, Belgium —50°43′2.89″N4°23′52.48″E —It is now a small town, but at the time of the battle it was a village in which most of the senior Anglo-allied officers were billeted the nights before and after the battle. It was here that Wellington wrote his after battle report (dispatch to Lord Bathurst, 19 June 1815). The inn in which Wellington stayed was located opposite the Church of Saint Joseph and is now the Wellington Museum (50°43′3.5004″N4°23′53.25″E).
