Soviet westward offensive of 1918–1919
The Soviet westward offensive of 1918–1919 was part of the campaign by the Russian Soviet Federative Socialist Republic into areas abandoned by the Ober Ost garrisons that were being withdrawn to Germany following that country's defeat in World War I. The initially successful offensive against the Republic of Estonia ignited the Estonian War of Independence which ended with the Soviet recognition of Estonia. The war against Republics of Latvia and Lithuania was more successful for the Soviets, and resulted in the Latvian Socialist Soviet Republic and Lithuanian Soviet Socialist Republics being established. In Belarus , the Belarusian People's Republic was conquered and the Socialist Soviet Republic of Byelorussia proclaimed. The campaign eventually bogged down and led to the Estonian Pskov Offensive, the White Russian Petrograd Offensives, the Lithuanian–Soviet War, the Latvian War of Independence, continuation of the Ukrainian–Soviet War and the start of the Polish-Soviet War. Soviet war aims. The newly-formed Red Army was growing in personnel, and Vladimir Lenin could gather enough strength to replace withdrawing Western curtain forces ("Западная завеса") by solid military and re-take the lands lost by Russia in 1917 by simply following the withdrawing  German army. Upon receiving the news about the German Revolution, on November 13, 1918, the Soviet government annulled the Treaty of Brest-Litovsk and issued orders to the Red Army to move in the direction of Belarus, Ukraine and the Baltic States in order to establish Soviet governments there. The newly-formed (on November 16) Western Army moved at night of November 17, 1918, into the operational vacuum created by the withdrawing Imperial German Army. This move, in the general direction of Belarus, Ukraine and Poland (parts of the latter within Imperial Russia were referred to as "Privislinsky Krai" ), according  to N. Davies, was code-named "Target-Vistula". The offensive in the Vistula River direction by the newly-formed Western Army had the aim of establishing similar Soviet governments in Belarus, Ukraine and Poland and to drive as far west as possible in order to join up with the German Revolution and to ignite the world revolution. Background. After signing the Treaty of Brest-Litovsk, Bolshevik Russia lost the European lands it annexed in the 18th and 19th centuries. Most of today's Poland, Belarus, Ukraine and the Baltic states were granted to the government of Germany, which in turn  decided to grant these states limited independence as buffer states. However, the German defeat on the Western Front and the internal dissolution of Austria-Hungary made the plans for the creation of Mitteleuropa obsolete. In November and December, the German army started a retreat westwards. Demoralised officers and mutinous soldiers abandoned their garrisons "en masse" and returned home. The areas abandoned by the Central Powers became a field of conflict between local puppet governments created by Germany as part of its plans, local nationalist governments that sprung up after the withdrawal of the German forces, Poland, and the Bolsheviks wanting  to incorporate these areas into Soviet Russia. Belarusian, Estonian, Latvian, Lithuanian, Ukrainian and even Cossack national governments were formed. Internal power struggles prevented any of the governments in Belarus from gaining lasting power. In Ukraine the situation was even more complex, with an ongoing conflict between Nestor Makhno's anarchists, communists, the White Movement, various governments of Ukraine and the reborn Polish Army. The entire region abandoned by the German forces became a gigantic free-for-all theatre, where dozens of factions competed for power. The Bolsheviks were also implementing a new strategy, "Revolution from abroad" ("Revolutsiya izvne"—literally, "revolution from  the outside"), based on an assumption that revolutionary masses desire revolution but are unable to carry it out without help from more organized and advanced Bolsheviks. Hence, as Leon Trotsky remarked, the revolution should be "brought on the bayonets" (of the Red Army), as "through Kiev leads the straight route for uniting with the Austro-Hungarian revolution, just as through Pskov and Vilnius goes the way for uniting with the German revolution. Offensive on all fronts! Offensive on the west front, offensive on the south front, offensive on the all revolutionary fronts!". The concept was developed in 1918 but officially  published under that name first in 1920 ("Wojennaja Mysl i Riewolucija", 3/1920, Mikhail Tukhachevsky. Offensives. Estonian direction. The Gdov and Yamburg Detachments of the 7th Red Army attacked the German Infanterie-Regiment Nr. 405 defending the city of Narva on 22 November 1918. The 6th Red Division captured the railway junction of Tapa from the freshly formed Estonian 4th and 5th Regiments on Christmas Eve and advanced to from the capital Tallinn. On 29 November in Narva, Estonian Bolsheviks led by Jaan Anvelt proclaimed the Commune of the Working People of Estonia (ETK). In South Estonia, the 49th Red Latvian  Rifle Regiment took the railway junction of Valga on 17 December and the city of Tartu on 24 December. The Estonian Army stopped the 7th Red Army's advance along the entire front on 2–5 January. Two days later Estonian forces began the counteroffensive to expel the Soviet forces from Estonia. A Finnish volunteer marine brigade landed in the rear of the 6th Red Division, and the 1st Estonian Division captured Narva on 18 January. Subsequently, the northeastern front stabilized along the Narva River. In South Estonia, the Estonian commando-type Tartumaa Partisan Battalion drove the Red Latvian rifle regiments  out of Valga on 31 January. The 7th Red Army was temporally forced out of the boundaries of Estonia. On 16 February the Red Army started a counteroffensive to recapture Estonia. The newly-formed Estonian Red Army gained the Setomaa, Vastseliina and Räpina Parishes by 15 March. The Estonian 2nd Division counterattacked and regained Petseri by 28 March. Similar combat took place between the Estonian Army and the Northern Group of the Latvian Red Army along the Ainaži–Strenči–Alūksne front stabilised in northern Latvia. In the positions along the Narva River, the Estonian 1st Division repelled 7th Red Army  attacks. Polish direction. The Red Army entered Polotsk on 21 November, Drissa and Rahachow on 22 November, Zhlobin on 24 November, Babruysk on 28 November, Barysaw on 3 December, Slutsk on 8 December and Igumen on 9 December. On 10 December 1918, the Red Army entered Minsk almost unopposed, putting an end to the short-lived Belarusian People's Republic. On 1 January 1919, the Socialist Soviet Republic of Byelorussia (SSRB) was proclaimed in Smolensk. On 8 January, the SSRB government relocated to Minsk. At the same time, Polish and Belarusian self-defence units sprung up across western Belarus. Ill -equipped and composed mostly of local recruits, they were determined to defend their homes from what the newspapers described as a "Red menace". Similar Bolshevik groups were operating in the sector and a series of skirmishes ensued. The Polish-Soviet struggle over Vilna in the first week of 1919 was a sign of things to come, as the Polish militia was forced to withdraw after the first organised units of the Soviet Western Army entered the city. In response, the Polish Army started sending units eastwards to help the self-defence units, while the Soviets did the same but in  the opposite direction. Open conflict seemed inevitable. On January 12 Soviet High Command declared the goal of its "Target Vistula" operation: deep scouting towards the Neman River. On February 12 that goal was updated to include the Bug river.(Davies, p. 12) On that day Jukums Vācietis ordered the new Western Command to carry out a "reconnaissance in-depth" as far as Tilsit, Brest-Litovsk, Kowel and Rivne. He also ordered the securing of main railway junctions, including those in Vilna, Lida, Baranowicze and Luninets.(Davies, p. 39) Among the aims of the Bolsheviks was to drive through eastern and central Europe  and support the Revolutions in Germany and Austria-Hungary.(Davies, p. 29) The Bolshevik forces did not anticipate serious opposition on the way and saw the states of Poland, Belarus and Lithuania as mere ephemerides, unable to defend their own "temporary" borders. However, it is unlikely that the Soviets really expected to reach the Vistula. The military orders were full of propaganda. The main goal of the operation was likely to see how much territory could be opportunistically grabbed in the chaotic governmental flux caused by the aftereffects of postwar Eastern Europe before any serious independent governing authorities arose. (Davies, p.  12 and p. 13) Finally, the first Polish-Soviet clashes happened in mid-February, in the area of the towns of Bereza Kartuska and Mosty, where both armies clashed in a series of skirmishes. The Soviet offensive came to a halt by late February and it became apparent that the Red Army would not break through the Polish lines by half-hearted attacks. Both the Soviet offensive and the Polish counterattack started at the same time, which resulted in an increasing number of troops being brought to the area. In April the Bolsheviks captured Grodno and Vilna, but were soon  pushed out by the Polish counteroffensive. Romanian direction. In early 1918, Bessarabia, a former Russian province, united with Romania after two months of independence as the Moldavian Democratic Republic. The Soviet did not accept the union and tried to retake the region by force. However, it all amounted to several sporadic attacks along the Dniester River. The Russians also attacked to support Communist Hungary, which had its own war with Romania. That was to no avail, as the region was successfully defended against Bolshevik attacks. Aftermath. The Estonian and the Polish Armies proved to be far more capable opponents than  the Red Army had assumed. The Pskov Offensive of the Estonian Petseri Battle Group destroyed the Estonian Red Army, captured Pskov and expelled Soviet forces from the territory between Estonia and the Velikaya River on 25 May. The 7th and 15th Red Armies began a counteroffensive in Ingria and in the north of Pskov in July 1919, which regained most of the lost territories of Petrograd and Pskov regions. With weapons provided by Britain and France and operational support by the Estonian Army and the Royal Navy, the White Russian Northwestern Army began Offensive White Sword on 28 September 1919  with the aim of capturing Petrograd. The Northwestern Army approached to within of the city, but the 7th Red Army repulsed the White Russian troops, driving them back into Estonia. Although the orders for the "Target Vistula" operation were never withdrawn, the Soviet plans were soon made obsolete by growing Polish resistance and eventually by the Polish counter-offensive in April. Unable to accomplish their objectives, the Red Army withdrew from their positions and started a reorganisation. The Polish-Soviet War had begun. Historiography. The best known comprehensive historical analysis of the campaign against Poland was performed by Norman Davies  in his book "White Eagle, Red Star" (1972). Davies mentioned the codename for this offensive: "Target Vistula"; however, it is not commonly used in historiography.
