Those persons who wish to gain a clear idea of the battle of Waterloo have only to place, mentally, on the ground, a capital A. The left limb of the A is the road to Nivelles, the right limb is the road to Genappe, the tie of the A is the hollow road to Ohain from Braine-l'Alleud. The top of the A is Mont-Saint-Jean, where Wellington is; the lower left tip is Hougomont, where Reille is stationed with Jerome Bonaparte; the right tip is the Belle-Alliance, where Napoleon was. At the centre of this chord is the precise point where the final word of the battle was pronounced. It was there that the lion has been placed, the involuntary symbol of the supreme heroism of the Imperial Guard.

The triangle included in the top of the A, between the two limbs and the tie, is the plateau of Mont-Saint-Jean. The dispute over this plateau constituted the whole battle. The wings of the two armies extended to the right and left of the two roads to Genappe and Nivelles; d'Erlon facing Picton, Reille facing Hill.

Behind the tip of the A, behind the plateau of Mont-Saint-Jean, is the forest of Soignes.

Two hostile troops on a field of battle are two wrestlers. It is a question of seizing the opponent round the waist. The one seeks to trip up the other. They clutch at everything: a bush is a point of support; an angle of the wall offers them a rest to the shoulder; for the lack of a hovel under whose cover they can draw up, a regiment yields its ground; an unevenness in the ground, a chance turn in the landscape, a cross-path encountered at the right moment, a grove, a ravine, can stay the heel of that colossus which is called an army, and prevent its retreat. He who quits the field is beaten; hence the necessity devolving on the responsible leader, of examining the most insignificant clump of trees, and of studying deeply the slightest relief in the ground.
