II Cavalry Corps (Grande Armée)

II Cavalry Corps (Grande Armée) was a French military formation during the Napoleonic Wars. It was first formed in December 1806, but only enjoyed a brief existence under Marshal Jean-Baptiste Bessières. The II Cavalry Corps was reconstituted for the French invasion of Russia in 1812 and commanded by General of Division Louis-Pierre Montbrun who was killed in battle, as was his successor a few hours later. In the War of the Sixth Coalition, General of Division Horace François Bastien Sébastiani de La Porta led the corps in 1813. General of Division Antoine-Louis Decrest de Saint-Germain directed the corps in 1814. During the Hundred Days, Napoleon raised the corps again and entrusted it to General of Division Rémi Joseph Isidore Exelmans.

1806-1807
The II Cavalry Corps was formed on 16 December 1806 at the beginning of Emperor Napoleon's campaign in Poland. Placed under the command of Marshal Jean-Baptiste Bessières, it operated with the northern wing of the French corps that advanced across the Vistula. The remainder of the army's reserve cavalry formed the I Cavalry Corps under Marshal Joachim Murat. The II Cavalry Corps included the 2nd Dragoon Division under General of Division Emmanuel Grouchy, the 4th Dragoon Division led by General of Division Louis Michel Antoine Sahuc, the 2nd Cuirassier Division commanded by General of Division Jean-Joseph Ange d'Hautpoul, and the light cavalry division of General of Division Jacques Louis François Delaistre de Tilly. The corps was dissolved on 12 January 1807. The only notable action occurred at Bieżuń on 23 December 1806. After Grouchy's division seized Bieżuń on 19 December, the Prussian commander General-Leutnant Anton Wilhelm von L'Estocq sent Major Karl Anton Stephan de La Roche-Aymon and several units to recover the town. Upon arrival, the Prussians found that the French cavalry had been reinforced by infantry and artillery. Grouchy immediately attacked and drove La Roche-Aymon toward Soldau (Działdowo). The French dragoons crowded a portion of the Prussian force against a swampy forest and forced the surrender of 500 men and five artillery pieces.

1812-1814


The Corps was reformed in 1812 for the French invasion of Russia. Commanded by General of Division Louis-Pierre Montbrun, the initial strength of the corps was 10,436 cavalry and 30 horse artillery pieces. General of Division Horace François Bastien Sébastiani de La Porta led the 2nd Light Cavalry Division, General of Division Pierre Watier directed the 2nd Heavy Cavalry Division, and General of Division Jean-Marie Defrance commanded the 4th Heavy Cavalry Division.



The corps was heavily engaged at the Battle of Borodino on 7 September 1812. Early in the morning, the corps was moved up from reserve in support of Marshal Michel Ney's III Corps attacks on the flèches. Montbrun was killed during the struggle. Around 3:00 PM, the IV Corps under Viceroy Eugène de Beauharnais mounted a frontal assault on the Great Redoubt. The II Cavalry Corps, now led by General of Division Auguste-Jean-Gabriel de Caulaincourt charged the Russian infantry lines to the south of the position. Breaking through, the cavalry wheeled to the left and galloped into the open back of the Great Redoubt just as Eugène's infantry fought their way in from the front. The four Russian infantry regiments defending the redoubt were annihilated. During the melee Caulaincourt was slain while leading the 5th Cuirassier Regiment.

After the disaster in Russia, Napoleon ordered four bodies of cavalry to be rebuilt for his army in Germany. These were the Imperial Guard cavalry, the I Cavalry Corps led by General of Division Victor de Fay de La Tour-Maubourg, the II Cavalry Corps under General of Division Horace François Bastien Sébastiani, and the III Cavalry Corps under General of Division Jean-Toussaint Arrighi de Casanova. The I and II Corps were to have three heavy and four light cavalry divisions. On April 15, the II Cavalry Corps numbered 149 officers, 3,144 troopers, and 3,581 horses. At the end of April the I Cavalry Corps had 172 officers, 3,343 men, and 3,705 horses deployed along the Elbe River. The lack of trained horses and cavalrymen was one reason for the French defeat in 1813. On 15 May, the size of the I Cavalry Corps in Napoleon's main army had been raised to 9,800 troopers in 45 to 50 squadrons. On that date, the II Cavalry Corps in Marshal Michel Ney's army numbered 3,000 horsemen in 15 squadrons. At the battles of Lützen and Bautzen Napoleon only employed the I Cavalry Corps. The II Cavalry Corps and the II Corps missed Bautzen because Napoleon was dazzled by the possibility of capturing Berlin. Belatedly, the emperor realized that the Allies were offering battle at Bautzen and giving him an opportunity to smash them. But his orders to Ney were too late for the two corps to arrive in time.

After the summer armistice, the II Cavalry Corps numbered 10,304 men in 52 squadrons, supported by 18 guns. The corps fought in the Battle of Katzbach on 26 August 1813 under the overall command of Marshal Jacques MacDonald. As the French crossed the Katzbach River the cavalry became intermixed with the infantry, slowing down the advance. Early in the action, the II Cavalry Corps was driven off by Russian cavalry. The French infantry tried to hold off the charging Prussian and Russian horsemen but were unable to fire their muskets due to the heavy rain. When the Allied infantry advanced with bayonets and clubbed muskets, the French were routed. Fleeing down to the river bank the French foot soldiers found that the stream was now swollen by the rain and difficult to cross. Thousands were captured. A few days later, Napoleon hurled abuse at Sébastiani for mishandling the cavalry, though the unfortunate general was allowed to remain in command.

At the Battle of Leipzig on 16 to 19 October 1813, General of Division Antoine-Louis Decrest de Saint-Germain led the 2nd Heavy Cavalry Division, General of Division Nicolas François Roussel d'Hurbal commanded the 2nd Light Cavalry Division, and General of Division Rémi Joseph Isidore Exelmans directed the 4th Light Cavalry Division. Altogether, the corps numbered 5,680 troopers and 12 guns. On the 16th, the corps was attached to Marshal Jacques MacDonald's XI Corps in its attempt to turn the Allied right flank. Around noon the assault began and MacDonald drove back Johann von Klenau's Austrians. At this time, Sébastiani's advance was held up by a Russian cavalry corps led by Peter von der Pahlen at the village of Klein Possna. Ultimately, Napoleon failed to smash the Allies that day and suffered the loss of Germany as a result of his defeat at Leipzig. The II Cavalry Corps played a key role at the Battle of Hanau on 30 October. Together with the Imperial Guard Cavalry, they smashed the Bavarian left flank.

Saint-Germain commanded the II Cavalry Corps at the Battle of Vauchamps on 14 February 1814. It consisted of the 2nd Heavy Cavalry Division, also led by Saint-Germain, the 2nd Light Cavalry Division under General of Division Frédéric de Berckheim, and two horse artillery batteries. Saint-Germain led the 2,600-strong corps at the Battle of Laubressel on 3 and 4 March. General of Division Antoine Maurin led the 2nd Light Cavalry Division.

1815


Napoleon reformed the II Cavalry Corps for the Waterloo Campaign and appointed Exelmans to command it. The corps comprised the 9th Cavalry Division led by General of Division Jean Baptiste Alexandre Strolz, the 10th Cavalry Division under General of Division Louis Pierre Aimé Chastel, and two horse artillery batteries. Each division was made up of two brigades and each brigade consisted of two dragoon regiments. The corps included the 4th, 5th, 12th, 13th, 14th, 15th, 17th, and 20th Dragoon Regiments. Altogether, the corps counted 2,817 horsemen, 246 artillerymen, and 12 artillery pieces. On the afternoon of 15 June 1815, Exelmans led his cavalry in a vigorous pursuit of the Prussian rear guard. His dragoons defeated the 6th Uhlan Regiment and chased an infantry battalion out of the woods near Gilly, Belgium.

Exelmans was ordered to hold the right flank during the Battle of Ligny on 16 June. On the 17th, he accurately reported the position of 20,000 Prussians at Gembloux, but he was unable to interfere with their retreat, having only 3,000 cavalry. On that day, his corps was placed under the command of Marshal Emmanuel Grouchy. On 18 and 19 June at the Battle of Wavre, Exelmans' troopers only played a small role. During the fighting on the 19th, Strolz held the extreme left flank on the west bank of the Dyle River while Chastel watched the far right flank on the east bank. There was a clash at Namur on the 20th in which the 20th Dragoon Regiment of the II Cavalry Corps was engaged.

In one of the last actions of the Napoleonic Wars, Exelmans led Strolz's division, the 2nd Cavalry Division under Hippolyte Guillaume Piré, three battalions of the 44th Line Infantry Regiment, and a half battalion of the Sèvres National Guard in hunting down Oberstleutnant Eston von Sohr's Prussian cavalry brigade. In the Battle of Rocquencourt on 1 July, the 3rd Brandenburg and 5th Pommeranian Hussar Regiments were wrecked, suffering 500 casualties out of the 750 horsemen in Sohr's brigade. French losses were negligible.
