Battle of Ligny

Definition and stakes

Archibald Frank Becke 1911 Encyclopædia Britannica (1911)

Probably Wellington's failure to co-operate at Ligny had heightened the Prussian chief-of-staff's unworthy suspicions of the good faith and soldierly qualifications of the British marshal; and it was well for the allies that Blücher was able to resume command before Napoleon had time to profit from the dissensions that would probably have arisen had Gneisenau remained in control. The casualties in the hard-fought battle of Ligny were very heavy. The Prussians lost about 12,000 men and 21 guns, and the French 8500; in Ligny more than 4000 dead lay on an area of about 400 sq.

The messenger who was sent to inform Wellington of the retreat of the Prussian army, was shot on the way; and it was not until the morning of the 17th that the Allies, at Quatre Bras, knew the result of the battle of Ligny. The Duke was ready at daybreak to take the offensive against the enemy with vigour, his whole army being by that time fully assembled. But on learning that Blucher had been defeated, a different course of action was clearly necessary.

It may be asked, what then should have been the conduct of the English General, after the battle of Ligny and the engagement of Quatre Bras? On this point posterity will not entertain two opinions: he ought, in the night between the 17th and 18th, to have crossed the forest of Soignes, by the road of Charleroi; the Prussian army ought also to have crossed it by the road of Wavres; the armies would have effected a junction by break of day in Brussels
