Napoleon organized the Grande Armée the largest army assembled up to that point in European history. After a whole day of preparation by Morand and Eblé, the invasion commenced on Midsummer, 24 June 1812 with Napoleon's army crossing the river. Half of them were foreigners; Polish legions formed the largest foreign contingent); 120,000 were conscripts.[2] Within a few days, almost half a million men from this multinational army - split up into five columns - crossed the river Neman and entered the Russian Empire. The numbers mentioned below are based on estimates made by Clausewitz, in his book "On War" and not on the estimates in "History of the Consulate and the Empire" by Adolphe Thiers, who wrote that 600,000 men in total were moved but not all of them crossed the Neman.[3]
X Corps (with the Prussian Corps) (30,000) commanded by Marshal Jacques MacDonald. They crossed the Niemen at Tilsit, now Sovetsk on the 24th.[4] He moved north in Courland but did not succeed in occupying Riga. Early August he occupied Dunaburg; early September he returned to Riga with his entire force.[5] A few days after the French left Lithuania, he drew back to Königsberg, followed by Pyotr Wittgenstein. On 25 December Yorck (von Wartenburg) found himself isolated when the Russian army blocked the road during the retreat. After five days he was urged by his officers (and in the presence of Clausewitz) at least to neutralization of his troops and an armistice. According to Minard, about 6,000 men returned to Poland, according to Clausewitz 5,000 men, but Yorck's resolution had enormous consequences.[6]
Imperial Guard (33,000-56,169[9]) commanded by Marshal Jean-Baptiste Bessières (Guard Cavalry); Marshal François Joseph Lefebvre (Old Guard); Marshal Edouard Mortier (Young Guard). The Guard did not take part in the fighting, but during the retreat, the Old Guard was the only unit that retained a semblance of order. The cavalry of the Guard was almost wiped out. About 7,000 Guards succeeded to arrive at the Berezina.[10]
Attached to the Young Guard were many multinational units e.g. the Polish Legion of the Vistula under Michel Claparède (7,000), Velites of Turin and Florence, and a Spanish pioneer battalion. Only about 1,500 returned.
Grand Quartier, Headquarter's guard, Equipages, Artillery General Park, engineers and other services 14,000 (French, Swiss, Polish, Portuguese) there were attached few multinational units e.g. Portuguese chasseur à cheval, Polish Vistula Uhlan, Neuchâtel (Swiss) battalion.
I Corps (72,000-96,000) commanded by Marshal Louis-Nicolas Davout. The strongest corps left Vilnius on 1 July, occupied Minsk, beat Bagration at Mogilev and with only 20,000 men left he went to Smolensk and joined the main army. Only 1,800 arrived at the Berezina.
II Corps (37,000-42,000) commanded by Marshal Nicolas Oudinot crossed the Niemen was sent to the other side of the Viliya and expected to join with McDonald to combat Wittgenstein, who protected the road to St Petersburg. This corps left mid-October after losing the Second Battle of Polotsk; it was joined by IX corps (reserve).[11] Arriving at the Berezina before Wittgenstein they played a key role in securing the crossing of the river; Nicolas Joseph Maison took over.[12] 300 were able to leave the country?
III Corps (40,000) commanded by Marshal Michel Ney. He defended downstream the 4th pontoon bridge at Aleksotas which could be used to escape; he then went to Polotsk. During the retreat his corps was in the rear. After being cut off from the main army in the Battle of Krasnoi Ney managed to escape in heavy fog and thin ice over the Dnieper River but without his artillery.[13]
Reserve cavalry (vanguard)
Marshal Joachim Murat, his brother-in-law, under King of Naples, followed with (21,000) Napoleon to Vilnius and Vitebsk
It followed behind the central force and (81,000) crossed at Pilona and avoided Vilnius
IV Corps (46,000) commanded by General Eugène de Beauharnais, Viceroy of the Kingdom of Italy. They crossed the Niemen 20 km upstream near Pilony/Pilona.[14][15][16] Unlike the I, II and III Corps Napoleon's stepson had orders to avoid Vilnius on his way to Vitebsk; only 1,600 arrived at the Berezina.
Napoleon's brother Jérôme Bonaparte King of Westphalia (62,000) crossed the Niemen near Grodno on 1 July,[16] and moved towards Bagration's (second western) army. On the order of Napoleon Davout secretly took over the command on 6 July.[18] In the Battle of Mir Jerome let Platov escape by deploying too few of Poniatowki's troops.[19] Jérôme was sent to Slutsk but left the army after being criticised by Davout.[20] He went home at the end of July,[21] taking a battalion of guards with him.[22] Davout took over the command of Latour's cavalry, trying to prevent Bagration from moving north.
V Corps (36,000 Polish) commanded by General Józef Poniatowski. He joined Davout and went to Mogilev and Smolensk. Early November Zajączek took over the command but the corps ceased to exist after the Battle of Krasnoi; Dombrowski stayed around Minsk; 8,000 men arrived at the Berezina.
VIII Corps (17,000 Westphalians) under Vandamme. Early July Jérôme Bonaparte took over and Vandamme was sent home. Jérome resigned on 15 July when he found out Davout had been secretly given the command.[22] Early August the command was given to Junot.[23] Junot didn't take part in the Battle of Smolensk (1812) as he was sent to bypass the left flank of the Russian army, but then got lost. Junot was blamed for allowing the Russian army to retreat at the Battle of Valutino; General Rapp took over.[24] After the Battle of Borodino the corps had only 2,000 men left.[25] They were ordered to stay behind and clear up the site. At the end of the war 1,200 arrived in Poland.[26]
With French forces moving through different routes in the direction of Vitebsk, a first major engagement took place on 25 July at the Battle of Ostrowno.
Southern flank
VII Corps (17,000) commanded by General Jean Reynier. He stayed in the Grodno region to protect the Duchy of Warsaw against Tormasow; on 26 December between 5 and 11,000 arrived in Poland.[27]
XII Corps (with the Austrian Corps) (34,000) commanded by Field Marshal Karl von Schwarzenberg crossed the Bug on 2 July on a pontoon bridge to go after Bagration and Tormasow.[8][28] He was prevented from joining up with Davout. The VII corps came under his command when Reynier fell back. When Tormassov occupied Brest (Belarus) at the end of July, he was cut off from supplies.[29] On 18 September he withdrew when Pavel Chichagov arrived from the south.[30] Schwarzenberg won the Battle of Wolkowisk. He crossed the Polish border on 14 December 1812.[31] Many survived.
Reserve units in Poland and Prussia
Several units marched to Russia in the late stage of the campaign. In November, the division of Durutte assisted Reynier. In December Loison was sent to help extricate the remnants of the Grand Army in its retreat.[32] Within a few days many of Loison's unexperienced soldiers died of the extreme cold.
[33] Napoleon arrested him for not marching with his division to the front.
XI Corps (50,000) commanded by Marshal Pierre Augereau. This corps did not participate in military operations in Russia, and Augereau never left Berlin. Augereau also had at his disposal a division of 10,000 Danes under General Johann Ewald, which remained in Holstein for the duration of the campaign.[34][35]
IX Corps (30,000 French) commanded by Marshal Claude Victor-Perrin. Early August his corps was in Tilsit, at the end of September the majority arrived at Smolensk;[25] At the end of October he took over the command from St. Cyr, but lost the Battle of Chashniki and the Battle of Smoliani and unable to retake Polotsk.[11] He had orders to follow Oudinot; 3,500 arrived at the Berezina and fired the bridges behind them.
In addition, National Guard units had been conscripted for full military service defending the frontier of the Duchy of Warsaw. With these included total forces on the Russian border and in Russia came to around 685,000 men. This vast commitment of manpower severely strained the French Empire — especially considering that there were a further 220,000 French troops fighting in Iberia and over 100,000 more in Germany and Italy.
The total is 643,500 men, but at least 130,000 were auxiliary troops, involved in the supply of the army.
Anthony Joes in Journal of Conflict Studies wrote that:[40]
Figures on how many men Napoleon took into Russia and how many eventually came out vary rather widely.
Georges Lefebvre suggested that Napoleon crossed the Neman with over 600,000 soldiers, only half of whom were from France.
Felix Markham suggested that 450,000 crossed the Neman on 24/25 June 1812, of whom less than 40,000 recrossed in anything like a recognizable military formation.
Eugene Tarle suggested that 420,000 crossed with Napoleon and 150,000 eventually followed, for a grand total of 570,000.
Riehn provides the following figures: 685,000 men marched into Russia in 1812, of whom around 355,000 were French; 31,000 soldiers marched out again in some sort of military formation, with perhaps another 35,000 stragglers, for a total of less than 70,000 known survivors.
Whatever the accurate number, it is generally accepted that the overwhelming majority of this grand army, French and allied, remained, in one condition or another, inside Russia.
Minard's infographic (see below) depicts the march ingeniously by showing the size of the advancing army, overlaid on a rough map, as well as the retreating soldiers together with temperatures recorded (as much as 30 below zero on the Réaumur scale) on their return. The numbers on this chart have 422,000 crossing the Neman with Napoleon, 22,000 taking a side trip early on in the campaign, 100,000 surviving the battles en route to Moscow and returning from there; only 4,000 survive the march back, to be joined by 6,000 that survived that initial 22,000 in the feint attack northward; in the end, only 10,000 cross the Neman back out of the initial 422,000.[41]
Adam Zamoyski estimated that between 550,000 and 600,000 French and allied troops (including reinforcements) operated beyond the Niemen, of which as many as 400,000 troops died.[42]
The forces immediately facing Napoleon consisted of three armies,[43] operating around the Western Dvina, the Dnieper and the Bug (river), comprising 175–250,000 Russians and 15,000 Cossacks, with 938 guns as follows:
First Western Army under Emperor Alexander I with General of Infantry Mikhail Barclay de Tolly as a field commander numbered 104,250 men and 7,000 Cossacks with 558 guns.[44] Tolly interrupted his service for five months.
IV Infantry Corps General Lieutenant Shuvalov, since 25 August General Lieutenant Alexander Ivanovich Ostermann-Tolstoy. When retreating from the Niemen, they forgot to give Ivan Semyonovich Dorokhov, leading a cavalry, the order to withdraw. He was cut off by the enemy from the main forces but succeeded to connect with Bagration.[46]
VI Infantry Corps General Lieutenant Dmitry Dokhturov, who was stationed near Lida was cut off from the main forces of the 1st Army. He was able cutting across the advancing French army and connect;[47] involved in the Battle of Borodino and Maloyaroslavets.
Third Reserve Army of Observation General of the Cavalry Alexander Tormasov numbered 38,000 men and 4,000 Cossacks, with 164 guns.[44] His headquarters were in Lutsk.[43] When the Moldavian army arrived, he handed over the supreme command to Chichagov and took over Bagration's command of the reserve of the main army. Instead Dmitry Golitsyn was appointed.
Kaluga Reserve Corps (General of the Infantry of Mikhail Miloradovich). As governor of Kyiv he was tasked with assembling and training volunteer militia troops in the "hinterland"; he returned to action in the Battle of Borodino.
These forces, however, could count on reinforcements from the second line, which totalled 129,000 men and 8,000 Cossacks, with 434 guns and 433 rounds of ammo.
Of these, about 105,000 men were actually available for the defence against the invasion. In the third line were the 36 recruit depots and militias, which came to the total of approximately 161,000 men of various and highly disparate military values, of which about 133,000 actually took part in the defence.
Thus, the grand total of all Russian forces was 488,000 men, of which about 428,000 gradually came into action against the Grande Armée. This bottom line, however, includes more than 80,000 Cossacks and militiamen, as well as about 20,000 men who garrisoned the fortresses in the operational area.[b]
Sweden, Russia's only ally besides England, did not send supporting troops. But the alliance made it possible to withdraw part troops from the 45,000 men Russian corps Steinheil from Finland and use it in the later battles (20,000 men were sent to Riga and Polotsk).[48]
Notes
^The appointment of Wittgenstein as commander-in-chief of the united Russian and Prussian armies provoked open hostility from his new subordinates and, at the same time, from his seniors: Miloradovich, Barclay de Tolly, Langeron, Platov and Tormasov. Tormasov refused to obey Wittgenstein altogether and left the army, while Miloradovich stayed and became the "official speaker" for the opposition.[45]
