Grouchy’s positions June 17th, 1815

Marshal Grouchy was in Gembloux with III Corps commanded by General Vandamme and IV Corps commanded by General Gerard. The 4th Cavalry Division, commanded by Pajol, and the 21st infantry division, under Teste (from Lobau’s corps), formed the remainder of his force. Reconnaissance by Pajol's horsemen during the 17th found that the Prussians had left Namur.

Final movements June 18th 1815

At or about 6 am June 18, 1815 Grouchy reported to Napoleon that the Prussians had left Tourinnes by marching all night. He further reported that he was moving on Wavre with all haste. At 10 am Grouchy reported to Napoleon that the Prussian I, II, and III Corps were marching in the direction of Brussels, and that Prussian officers were talking of joining Wellington to offer battle to the French army. His despatch included a Prussian requisition form by way of proof. He noted that by attacking and standing at Wavre, he could block the Prussians from intervening against the rest of the French army. At 11:30, Grouchy and his corps commanders heard in the distance the noise from the Grand Battery as the Battle of Waterloo

 started. Grouchy’s corps commanders, especially Gérard, suggested that they should “march to the sound of the guns” Grouchy, however, had written and verbal orders from Napoleon to march on Wavre and to engage the Prussians there, and knew that Marshal Ney had been taken to task by Napoleon two days earlier for not following orders at the Battle of Quatre Bras

. Grouchy therefore declined to follow his subordinates' suggestions, correctly pointing out that Napoleon had more than enough force to deal with Wellington. Minutes after this conversation, Exelmans reported strong Prussian positions 5 km from Wavre. At 1 pm, elements of Exelmans' cavalry were in contact with the Prussian 14th Brigade’s rear guard. Further argument was ended by the arrival at 4pm of another order from Napoleon, repeating the instruction to Grouchy to attack the Prussians before him.

The race to the Dyle

The battle to come now hinged on control of the crossings over the river Dyle. Every passing moment would see more Prussian brigades passing through Wavre on the way to Waterloo; by 1:30 pm 7th and 8th Brigades passed through Wavre and would next be seen at 7:30 pm pushing an Imperial Guard

 battalion of the 1st Kurmark Landwehr Regiment defended the Bierge bridge by removing timbers from it under French fire and countercharging any attempt to repair it. The Kurmarkers held the right bank of the stone bridge at Wavre for some time, forcing Vandamme's troops to waste precious time taking it. Once this was done the French rushed across the bridge and straight into a vicious street fight. A battalion of the 2nd Kurmark Landwehr Regiment moved to support the 1st and threw the French back across the bridge. A renewed French assault penetrated further down the same street, only to be ambushed from side streets by the fusiliers of the 1st Kurmark Landwehr and 30th Line Infantry Regiments using point blank musketry. A bayonet charge sent the French scrambling across the bridge again. This seesaw battle would continue throughout the night. Later attacks by the French upon Wavre met with no more success. The Prussians assigned another battalion and three guns to the bridge. The bridge at Bas-Wavre had been destroyed by the Prussians. The attacks by Lefol upon the bridge of Bierges had no more success, being hampered by muddy ground and the tough defence of the Prussian 31st Line Infantry Regiment supported by the 2nd battalion of the 6th Kurmark Landwehr Regiment and a horse battery

. Three small batallions and three squadrons of cavalry under Stengel were to guard a bridge to the west at Limal.

Marshal Soult's 1 pm letter ordering Grouchy to move quickly to join Napoleon and to attack Bulow arrived after 6 pm. Grouchy at once began gathering additional divisions and headed to Limal, arriving at 11:00 pm, where he found that Pajol's cavalry had forced the bridge there. Prussian scouting cavalry noticed the strong French columns moving to Limal and the Prussian 12th Brigade moved covering forces to the area. The Prussians made a bayonet charge in an attempt to retake Limal but without success. Night closed the major actions of the battle of Wavre, although outposts fired on each other all night.

was lost as the French left, center, and right, of their positions collapsed within a few minutes of each other.

Grouchy was across the Dyle, but meanwhile the Battle of Waterloo by this time had been irrevocably lost, and the remnants of the Armėe du Nord were streaming south towards the safety of French territory.

Fighting renewed in the early hours. The forest south of Limal was forced by 9 am. Thielmann elected to retreat, as the campaign had been decided by the fighting elsewhere. The definitive report of the victory at Waterloo reached Thielmann at 10 am as the retreat started. Grouchy, watching the retreat, was beginning his planned move upon Brussels when the news reached him at 10:30 am that Napoleon had been defeated. Though in shock, Grouchy realised he was in danger of being trapped and his entire command destroyed. He at once had Exelmans move his cavalry to secure the bridges and began a retreat by forced marches that would take him back to Paris.

Conclusion

While the battle ended in a French victory, with the Prussians in retreat and Grouchy firmly athwart Prussian lines of communication to the east, this situation lasted a total of 30 minutes and thus it proved hollow. The Prussians held their ground long enough to allow Blücher’s transfer of 72,000 troops to Wellington’s aid at Waterloo. Thus to the Prussians, the battle was a strategic success, as it contributed to a decisive victory at Waterloo. In addition, the Prussian rearguard of 17,000 troops tied down 33,000 French troops that could have otherwise taken part at Waterloo.
