This is off topic, but some things must be corrected.
Polish historians have their own view of war 1918-20, which is based on polemic, "personality cult" and distortion of dates, facts, as there are
some really shameful facts for them (attacks and war on allied forces). Country had a policy of expansionism and it wasn't Bolsheviks, but
neighboring countries their first targets. Heavily decimated by occupation and WWI Lithuania became one of them. 500 year old border wasn't suitable
anymore for Poland, only 700 year old with Latvia remained unchallenged, just without Lithuania in between. Surely Pilsudski was great for Poland, but
not so great as some like to portray him.
Dvina and Dvinski are in reality Daugava and Daugavpils, river and Latvian city. There were major forces from Latvia and Lithuania fighting Bolsheviks
with major victory, breaktrhough in Zarasai campaign 1919-08-26. This lead to Lithuania controlling battlefield 1919-08-30 from Dviete to Kalkuni
(part of Daugavpils on one side of the river) to Turmantas. That part became entrenched as main forces were transfered to fight Polish invasion at the
People's Commissar for Foreign Affairs of the Russian SFSR Georgy Chicherin sent out peace offers (after this campaign) to other countries, to
Estonia 1919-08-31, to Lithuania 1919-09-11. Bolsheviks signed peace treaty with Estonia 1920-02-02. Peace negotiations were proposed by Finland
1920-03-25, Latvia 1920-03-26, Poland 1920-03-27. Lithuania answered peace offer on 1920-03-31. Peace agreements signed by Lithuania 1920-07-12,
Latvia 1920-08-11, Poland (cease fire) 1920-10-12.
State of war over Vilnius or frozen conflict with Poland lasted for another few decades and prevented forming strong defensive alliance with Latvia,
Estonia as both didn't want to become involved in conflict with Poland. It became a reason of demise for all at the beginning of WWII.
Story doesn't end there, Lithuania got only part of Vilnius, Suvalkai were left for Poland. One side looks at Suvalkai, another at Vilnius, Germany
at former Prussian lands. A reason for future conflict to weaken neighboring countries? Similar schemes were used numerous times.
