The Sejny Uprising ( _pl. Powstanie sejneńskie) or Seinai Revolt refers to a 1919 uprising by Polish irregular forces, later aided by the regular Polish army, in the area of the town of Sejny (Lithuanian: "Seinai"), against Lithuanian authorities. Action began on August 23, 1919 and by September 9, 1919 Polish forces had secured the area. Control of the town changed hands several more times during the course of the following year; Sejny has remained within Poland since late 1920. The battle was part of a long-term conflict that arose in the twentieth century between Poland and Lithuania over ethnically-mixed territories in the area; the League of Nations and the Paris Peace Conference attempted to intervene in these conflicts.

The region had been occupied by Germany during World War I; after the German defeat, both Lithuanian and Polish administrative and military organizations vied for control of the town, and the uprising occurred immediately after the departure of the German occupational authorities. The town changed hands and during that time both sides used repressive measures.

The uprising damaged the plans of Polish leader Józef Piłsudski, who was planning a coup d'etat in Lithuania in order to establish a government there that would be willing to join his proposed Międzymorze federation. For that reason Piłsudski wished for the coup to be as bloodless as possible; the unplanned hostilities in Sejny further damaged Polish-Lithuanian relations, and the coup was prevented as the uprising drew the attention of Lithuanian police and intelligence forces to the activity of Polish intelligence in Lithuania.

Background

The lands surrounding the town of Suwałki had been variously part of Polish, German, and Lithuanian borderlands since the Middle Ages, and the borders in the area had shifted numerous times in the past. During the era of the Polish-Lithuanian Commonwealth, the town of Sejny itself, along with the rest of the Podlaskie Voivodeship, was part of the Kingdom of Poland since 1569 rather than the Grand Duchy of Lithuania it used to belong until then. However, the town had been controlled by Dominican friars from Vilnius. During the nineteenth century the town was part of Russian-controlled Congress Poland.pl icon [http://www.wspolnota-polska.org.pl/index.php?id=h23081919 Powstanie Sejneńskie 1919] on the pages of Association "Polish Community"] pl icon [http://www.sejny.home.pl/historia Historia] , official pages of Sejny town] According to contemporary Eduard Volter's statistics in 1889 Suwałki Governorate there were 57,8% Lithuanians, 19,1% Poles, 3,5% Belarusians.

This led to a conflict between Poland and Lithuania, as both sides claimed the area. The Germans, whose Ober-Ost administration of the former Suwałki Governorate was preparing to evacuate the area, initially supported the creation of a Polish administration in the area.pl icon cite journal | author =Tadeusz Mańczuk | year =2001 | month = | title =Z Orłem przeciw Pogoni.

thumb|right|250px|Selected lines of demarcation between Lithuania and Poland in 1919-1939.Since the Polish-Lithuanian talks in Paris were inconclusive, on July 18 1919,the Marshal of France, Ferdinand Foch, under the influence of Polish war mission in Paris and general Rozwadowski, [Makauskas, Bronius (1999)."Foch had been influenced by Polish war mission in Paris delivered favorable to Poles new administration line on July 26. //Foch under the influenced of general Rozwadowski question solved as technical rather than ethnic."] presented the new, favorable to Poles, line, which became known as the "Foch Line". The Lithuanian delegation was absent during the establishment of the demarcation line. The demarcation line ran from the German border in East Prussia, south of Lake Vištytis (with Wiżajny on the Polish side), north of Puńsk and then south of Lubowo. From there the line turned along the shores of Lake Galadusys, east of Bereźniki and along the Marycha and Igorka rivers to Neman. This left the southern part of the conflict area, incuding Suwałki and Sejny, in Polish hands, and the northern area in Lithuanian hands. The line roughly reflected the region's demographics, but still left significant minorities on both sides.

On July 26 the Foch Line was accepted by the Highest Council of the Entente as the provisional border between the two states. Under pressure from the Conference of Ambassadors, which would later become the League of Nations, both countries initially backed down on the issue; neither was satisfied, particularly as Polish forces were already in some areas up to 30 km over the line and showed no desire to retreat. Such repeated Polish violations of Foch line were protested in Paris. [http://query.nytimes.com/mem/archive-free/pdf?_r=1&res=9504E7D61F3EEF33A25755C0A96F9C946195D6CF&oref=slogin Poles Attacked By Lithuanians] . Walter Duranty, New York Times, September 6, 1920. Accessed on October 26, 2007.] Lithuanian military forces were allowed to enter the area before the German army withdrew, which led many local Poles to believe that the Lithuanians intended to capture the entire Suvalkai region, known in Lithuanian as "Suvalkija", and convince the Entente to accept this as a "fait accompli". Further, the Lithuanian forces in the disputed regions (about 1,200 strong) left Suwałki by July 7, but remained in Sejny, and formed a line on the Czarna Hańcza river - Wigry Lake, in violation of the Foch Line.

On August 12 1919, a Polish meeting in Sejny attracted over 100 delegates from neighboring Polish communities; the meeting passed a resolution that "only securing the area by Polish Army can solve the problem." On 17 August, a Lithuanian counter-demonstration was staged, whose participants in turn pronounced words of a recently issued Lithuanian volunteer army recruitment proclamation: "Citizens! Our nation is in danger! To arms! We shall leave not a single occupant on our lands!" Governments of both countries were encouraging the conflict. Prime Minister of Lithuania Mykolas Sleževičius visited Sejny and in his speech called Lithuanians to defend their lands "to the end, however they can, with axes, pitchforks and scythes".Piotr Łossowski, "Konflikt polsko-litewski 1918-1920", Książka i Wiedza, 1995, ISBN 8305127699, p.67] In turn, the Polish government - particularly the Polish chief of state, Józef Piłsudski - was supporting the secret Polish Military Organization (PMO), which was planning a coup d'etat that would topple the sovereign government of Lithuania. The Lithuanian government was not eager to cooperate with Poland, perceiving that it would lose its sovereignty under Piłsudski's Międzymorze federation scheme. Within Lithuania, the pro-Polish faction was supported by the Lithuanian general Silvestras Žukauskas and by politician Stanisław Narutowicz. The Sejny branch of the Polish Military Organization, led by Polish regular army officers Adam Rudnicki and Wacław Zawadzki, had been preparing for the uprising since August 16; PMO irregular forces numbered about 900 PMO members and local militia volunteers.

Lithuanian historian Vytautas Lesčius has stated that the coup was meant to be accompanied by a series of PMO uprisings across all of Lithuania, scheduled for August 1919. He bases this assertion on documents stolen from a safe at PMO headquarters, located in Polish-controlled Vilnius, documenting the coordination of PMO actions in Lithuania. According to the Polish historian Tadeusz Mańczuk, Piłsudski - who both historians agree was involved in planning the coup - did not want Polish-Lithuanian hostilities, and discouraged the local PMO activists from carrying out the Sejny uprising, which would have left any new Lithuanian government less receptive to Polish federative proposals. The local PMO disregarded his recommendations and launched the uprising, which while locally successful, led to the failure of the nationwide coup. A similar argument has been presented by Polish historian Katarzyna Pisarska.

Military skirmishes

The Polish uprising, led by undercover local PMO activists commanded by Polish regular army officers, began early in the morning of August 23, 1919. The date was chosen to coincide with the withdrawal of German troops from the territory. Details of the battles differ in the accounts of Lithuanian and Polish historians.

The first Polish assault was a success, and the PMO troops took Sejny and several neighboring communities and then advanced into territories within the Lithuanian side of the Foch line. The Suwałki PMO detachment had orders to capture the entire territory of the Sejny powiat up to the city of Simnas, but growing Lithuanian resistance prevented this. cite web|url=http://www.punsk.com.pl/saltinis/saltinis1_2007/5.htm" |title=Seinai – 1918-1920 metai |accessdate = 2007-09-27 |last=Paransevičius |first=Juozas Sigitas |language=Lithuanian ] On the evening of August 25 the first regular unit (41st Infantry Regiment) of the Polish army received an order to advance towards Sejny. The local Lithuanian militia and the regular army, gained an advantage over the irregular forces of PMO insurgents, and retook the city on August 26. Polish sources assert that Lithuanians there aided by a company of Germans volunteers, but Lithuanian sources assert that there are no facts supporting such findings.cite journal | last = Makauskas | first = Bronius | authorlink = | coauthors = | title = Pietinės Sūduvos lietuviai už šiaudinės administracinės linijos ir geležinės sienos (1920–1991 m.) | publisher = Voruta, No.27-30 |year=1999 | location = | pages = | quote = German participation among Lithuanian side is mentioned by Polish sources, but these claims are not supported by facts. | url = | doi = | id = ISSN 1392-0677 | isbn = ] Lithuanian forces recovered some important documents and property, freed the Lithuanian prisoners of war taken by Poles and, according to Mańczuk, executed several of the PMO fighters they found wounded. The Lithuanian forces retreated on the same day. Lesčius, who had access to Lithuanian army documents, states the retreat was motivated by a report that a Polish cavalry unit was approaching from Suwałki. Mańczuk states that the Lithuanians had received an erroneous report that a large force of Polish regular cavalry was operating in their rear, on the Lithuanian side of the Foch line - but no such regular unit existed, and the only Polish cavalry unit in the region was an irregular PMO unit under Lieutenant Rudnicki. He agrees that the Lithuanians received a report that Polish regular troops were approaching the town. Later the next day, during the afternoon of 26 August, the PMO forces in Sejny were joined by the Polish 41st Regiment.

The last Lithuanian attempt to retake the city was made on August 28, defeated by the combined forces of the Polish army and PMO volunteers. The Polish forces forced all Lithuanian troops to retreat beyond the Foch demarcation line by September 9. The Polish regular army units did not cross the Foch line, and refused to aid the PMO insurgents still operating on the Lithuanian side; these insurgents fought in some areas for two more months.

Polish sources give total casualties for the Sejny Uprising as 37; they have no numbers for Lithuanian casualties. Based on Lithuanian army reports, Lesčius states that on the heaviest day of fighting, August 25, the casualties consisted of 45 Polish soldiers and 3 officers killed (including the Sejny commandant), and 8 Lithuanian soldiers wounded.

Aftermath

After Poland acquired control of the town and its surroundings, Lithuanian schools were closed and Polish schools were opened. The Poles evicted the local Lithuanian clergy, whom they saw as a stronghold of Lithuanian nationalism in the region; the prominent seminary in the town was relocated. According to Lithuanian historian Vytautas Lesčius, the repressions directed at the Lithuanian population were even more widespread, including a ban on public use of the Lithuanian language, the closure of Lithuanian organizations numbering 1,300 members, all Lithuanian schools (with some 300 pupils) and printing presses, the confiscation of property, and the burning of Lithuanian books.cite book | last = Lesčius | first = Vytautas | authorlink = | coauthors = | title = Lietuvos kariuomenė nepriklausomybės kovose 1918-1920 | publisher = Vilnius University, Generolo Jono Žemaičio Lietuvos karo akademija |year=2004 | location = Vilnius | pages = p.278 |url = | doi = | id = | isbn = 9955423234 ] The New York Times, reporting on renewed hostilities a year later, described the 1919 Sejny events as a violent occupation, in which the Lithuanian inhabitants, teachers, and religious ministers were maltreated and expelled. [http://query.nytimes.com/mem/archive-free/pdf?_r=1&res=9504E7D61F3EEF33A25755C0A96F9C946195D6CF&oref=slogin Poles Attacked By Lithuanians] . Walter Duranty, New York Times, September 6, 1920. Accessed on October 26, 2007.] According to Juozas Sigitas Paransevičius, the uprising was a direct act of Polish government aggression against Lithuania. Polish historian Łossowski notes that both sides mistreated civilian population and exaggerated reports to gain internal and foreign support.

Polish historians - Łossowski, Mańczuk, Pisarska - agree that it contributed to the deterioration of Polish-Lithuanian relations, and that it further discouraged the antagonized Lithuanians from joining Piłsudski's proposed Międzymorze federation of states in the area.Piotr Łossowski, "Konflikt polsko-litewski 1918-1920", Książka i Wiedza, 1995, ISBN 8305127699, p.68] Piłsudski wished for the coup to be as bloodless as possible, criticized those who suggested a military action, and did not plan nor wish for the Sejny uprising to occur.Piotr Łossowski, "Konflikt polsko-litewski 1918-1920", Książka i Wiedza, 1995, ISBN 8305127699, p.66]

The Sejny uprising doomed the Polish plan to overthrow the Lithuanian government. PMO members in Lithuania stated that the Sejny uprising had damaged their reputation, and many of its former supporters rejected calls by PMO recruiters. Lithuanian police and intelligence intensified their investigation of Polish sympathizers, and the coup, originally scheduled for 28 August 1919, was delayed until September. The plans for the coup were soon uncovered by counter-intelligence, and Lithuanian Army officers moved to prevent it. The first arrests in the case were made on August 27 and continued until the end of September. During the investigations lists of PMO supporters were found, and the organisation was completely eliminated in Lithuania.cite book | last = Lesčius | first = Vytautas | authorlink = | coauthors = | title = Lietuvos kariuomenė nepriklausomybės kovose 1918-1920 | publisher = Vilnius University, Generolo Jono Žemaičio Lietuvos karo akademija |year=2004 | location = Vilnius | pages = p.259-278 |sbn = 9955423234 ]

A year later, the town was captured by Soviet Russia during the course of the Polish-Soviet War. On July 12, 1920 a Soviet-Lithuanian Treaty of 1920 was signed, granting Lithuania the right to control the Sejny area in exchange for the right of passage for Soviet forces through Lithuanian territory. As a matter of fact the terriotry was contolled by the Soviets already.Fact|date=October 2007 On July 19, 1920, the Lithuanians attacked the Polish defenders and recaptured the town. The Lithuanian authorities were once again established in the area. After the Battle of Warsaw in 1920, the Soviet forces were defeated, and the Polish Army again entered the Sejny area. The Lithuanian authorities persisted in their claim, and the town was an object of contention during the Polish-Lithuanian War. As the town was located only some 2 kilometres from the Lithuanian border, it was easily captured by Lithuanian forces. The assault was repelled and the Polish Army recaptured the town on September 9. On September 10, the last of the Lithuanian units retreated to the other side of the border, and on October 7 a cease fire agreement was signed, leaving Sejny on the Polish side of the border.
