Battle of Waterloo Map: Ground, Farms & Attack Axes — 18 June 1815

Historical plan of the Battle of Waterloo showing the battlefield around Mont-Saint-Jean on 18 June 1815

Quick answer: the Battle of Waterloo was fought on 18 June 1815 around Mont-Saint-Jean, south of Brussels in present-day Belgium. On a Waterloo map, the key features to find are Wellington's ridge, Hougoumont on the Allied right, La Haye Sainte in the centre, Papelotte and Smohain on the left, and Plancenoit to the south-east where Prussian pressure developed against Napoleon's right.

This is the map-first entry point into our larger Waterloo archive. For the full political context, order of battle, chronology and casualty discussion, read the complete Gallus Battle of Waterloo field guide.

How to read a Battle of Waterloo map

Waterloo makes more sense when the battlefield is read as ground rather than as coloured blocks. Napoleon's Army of the North approached from the south. Wellington's Anglo-Allied army occupied the Mont-Saint-Jean ridge to the north. The Prussian army under Gebhard von Blücher approached from the east and increasingly threatened the French right and rear.

1. Mont-Saint-Jean ridge

Wellington used the shallow ridge to conceal much of his infantry from French observation. It was not dramatic high ground; its value was that troops positioned behind the crest were harder to see and less exposed to direct artillery fire.

2. Hougoumont

Hougoumont sat forward of Wellington's right. Its walls, buildings and woods made it a powerful strongpoint. French attacks around the complex consumed troops and attention throughout the day without breaking the Allied right.

3. La Haye Sainte

La Haye Sainte stood close to the Brussels road in front of Wellington's centre. Its position made it tactically important because control of the farm affected how close French infantry and artillery could operate to the Allied line. The French eventually captured it late in the battle, when its defenders were running short of ammunition.

4. Papelotte, La Haye and Smohain

These positions anchored the Allied left and sat close to the direction from which Prussian formations would arrive. They help explain why Waterloo cannot be understood as a simple head-on contest between Napoleon and Wellington.

5. Plancenoit and the Prussian approach

Plancenoit lay behind and to the right of Napoleon's main position. As Prussian forces arrived, Napoleon had to divert troops away from the attack on Wellington to prevent his flank from collapsing. The battlefield therefore became two connected contests: breaking Wellington's line and containing Blücher's army.

The main French attack axes

The map also helps separate the major phases of the battle. Napoleon first committed major effort against Wellington's left-centre through d'Erlon's infantry attack. Later, Marshal Michel Ney directed mass cavalry assaults against the Allied centre-right. Late in the day the Imperial Guard was committed against Wellington's centre as Prussian pressure increased around Plancenoit.

These attacks did not happen on an empty tabletop. Farms, ridges, roads, wet ground, artillery positions and restricted approaches shaped what each formation could see and how quickly it could move.

Why the Waterloo map matters

A map makes three important things immediately visible. First, Wellington's defensive position depended on a ridge and forward strongpoints rather than a continuous fortress. Second, Napoleon had to attack while also watching an increasingly dangerous eastern flank. Third, the Prussians did not simply appear at the end: their approach progressively changed Napoleon's tactical choices.
