Grodno was a lonely Belarusian island, protected by German troops. Polish troops were pressing in from the west and Bolshevik troops from the east. German troops were slowly retreating northward from Ukraine and Belarus. In Grodno, Polish representatives were active, striving to pull the Belarusian army to the Polish side. First Lieutenant Jan Kwiatkowski was active there, while from the beginning of 1919 Stanisław Iwanowski (brother of
Vacłaŭ Ivanoŭski), who succeeded in dragging an entire single Belarusian battalion (about 500 soldiers), which was incorporated into the Kaunas Rifle Regiment of the
Lithuanian-Belarusian Division. He also organised local branch of the
Polish Military Organisation.
February 1919 On February 5, Poland signed an agreement with Germany regulating the withdrawal of the German army from western Belarus and giving the Polish army the opportunity to march eastward. On February 14, 1919, Polish troops came into contact with the Bolshevik army near
Vawkavysk.
March The Belarusian authorities, informed by the Germans of the agreement, began to leave Grodno in March 1919. Lithuanian authorities proposed moving the army to Sejny and Suwalki, which the Belarusians rejected. They obtained a loan of 4 million marks from the
Ukrainian People's Republic, which gave them some independence. It is possible that at that time the regiment ceased to be maintained from the Lithuanian budget and began to be maintained from Belarusian funds.
April In early April, German troops began evacuating Grodno. Col. Demidov pulled the 5th company from Kaunas to reinforce his position. On April 16, 1919, the Polish Army launched a wide-ranging
offensive against the Bolsheviks from
Lida to Vilnius, and entered Grodno. Gen. took over the command of the Grodno Fortress. When the regimental commander Col.
Kastuś Jezavitaŭ was in Warsaw on a Lithuanian diplomatic mission, the then-commander of the regiment Col. Uspensky signed an agreement with the Polish command on April 23, under which the regiment was to remain an autonomous unit within the Lithuanian army, but would subordinate itself to the Polish command in the fight against the Bolsheviks. On April 24, Jezavitaŭ returned to Grodno and defied this agreement, he wanted to evacuate the regiment, but the German and Lithuanian commands ordered him to stay. In view of this, on April 27 he himself left for Kaunas, leaving the command to Col. Antonov. Same day Polish troops appeared in Grodno, and on April 28 they disarmed and arrested Belarusian hussars. On April 29, German troops completely left Grodno, which came under Polish control. Earlier, on April 19, 1919, the Polish cavalry under
Władysław Belina-Prażmowski captured Vilnius from Bolsheviks. The Lithuanian government appointed a Russian, an officer of a Belarusian regiment, Leonid Kalugin, as commander of the city of Grodno in place of Demidov, although Demidov did not resign.
May Initially, the coexistence of Polish and Belarusian troops was good. On May 3, a joint parade was held. On May 5, the hussars were dismissed and went with the 5th company to
Druskininkai and then to
Kaunas. On May 30, Falewicz handed over an order from front commander Gen.
Stanisław Szeptycki to move to Slonim. Col. Antonov refused, citing the April 23 agreement.
June 1919 Poland feared a conflict with Germany at the time, so it could not condone the stationing of an alien unit in Grodno, so they decided to disarm the regiment on June 1. Soldiers were disarmed, looted, and publicly humiliated by the Polish soldiers, who even ripped off the Belarusian
officers' insignias from their uniforms and trampled these symbols with their feet in public, because this unit refused to carry out the Polish orders and remained loyal to Lithuania. The
Lithuanian and Belarusian
flags, and signs with the Lithuanian coat of arms were torn off, with the Polish
gendarmes dragging them on the dusty streets for ridicule; instead of them, Polish signs and
flags were raised in their place everywhere in the city. 4 June 1919 report sent to the
Government of Lithuania about the 1st Belarusian Regiment military actionsOn June 3 the head of the Polish state Józef Piłsudski arrived in Grodno. On this occasion, the guard was removed from the Belarusian barracks, and soldiers were allowed to move freely around the city. Pilsudski received Col. E. Haydukevych, who was replacing the ill Antonov in the role of commander. On June 11, the Polish command separated the soldiers according to religion, Catholics were escorted to Polish barracks, while Orthodox and Jews were demobilized. Officers were offered service in the Polish army. Demidov and for a short time Antonov were arrested. Officers were not allowed to go to Kaunas, but some were allowed to go to the White Russian army of Gen.
Nikolai Yudenich. A part of the Belarusian regiment's soldiers and officers escaped to
Kaunas to continue serving Lithuania. == Organization and command ==
