[1] In October 1919, the Kaunas Battalion, led by officer Edvardas Adamkavičius, fought against the Bermontians near Baisiogala, Raseiniai and Tauragė.
On 9 January 1920, a year after the formation's beginning, the battalion was transformed into a regiment, being given the name of the Samogitian Duke Butigeidis.
In addition to other Lithuanian units, the regiment took part in the Battle of Giedraičiai, where the Polish Army was heavily defeated, stopping its offensive to Kaunas.
The Lithuanians took 200 prisoners of war, 2 artillery guns, 24 HMGs, around 200 wagons, 50 horses, 250 rifles, 9 mortars and 24 field kitchens.
In 1928, the regiment was given a flag of the 3rd class of the Order of Vytautas Cross with the inscription "Meilė Lietuvos mūs žingsnius telydi" (English: Love of Lithuania guides our steps).
