and Irkutsk, from where they found safe passage to the port of Vladivostok and various ports of China and Manchuria. On June 1, 1920, the first organised group of Polish soldiers arrived to the port of Gdańsk. After three months on-board British ships, 120 officers and more than 800 soldiers and NCOs reached Poland. Some of them saw it for the first time. Polish-Bolshevik War The General Staff of the Polish Army initially wanted to demobilise all the veterans. However, all of them volunteered and were finally accepted. They were transferred to Greater Poland, where they were formed into an infantry battalion and an "Officers Legion". Soon they were joined by approximately 5 000 volunteers from Kalisz, Kutno, Łódź, Włocławek and other towns of Western Poland and the "Officers Legion" became a core of the reformed Siberian Brigade () formed on July 12, 1920. The new unit was composed of two regiments: the 1st Siberian Infantry Regiment under Franciszek Dindorf-Ankowicz and the 2nd Siberian Infantry Regiment under Józef Werobej. The brigade was put under command of one of the Siberian veterans, colonel Kazimierz Rumsza. Although the training of the new recruits was not finished, the extremely difficult situation on all fronts of the Polish-Bolshevik War forced the General Staff to transfer it to the front. The brigade was transferred to the area of the Modlin Fortress and on August 13 joined the 5th Army under general Władysław Sikorski. The Siberian Brigade became a core of the Polish defence lines in the area and managed to hold out all assaults on the fortress organised by the Red Army. After the Battle of Warsaw the brigade started a pursuit after the fleeing enemy forces and broke through the enemy front in the battles of Borków, Zawady and Joniec. Between August 22 and August 24, 1920, the Brigade fought heavy battles against the Red 4th Army and 3rd Cavalry Corps under Gay Dimitrievich Gay. Its elements took part in the later Battle of the Niemen and several skirmishes with Lithuanian forces occupying the region of Suwałki. Interbellum After the Peace of Riga had been signed the 2nd regiment was demobilised, while the 1st regiment remained in the Polish Army. On August 22, 1921, it was renamed to 82nd Siberian Infantry Regiment (). It was stationed in Brześć Litewski. In 1937 the name of Tadeusz Kościuszko, the original patron of the regiment, was added
