ENFor the first time, researchers have published a Lithuanian insurgent march from 1831 written by an unknown author. The manuscript was found in a handwritten song collection titled Dainų rinkinys (“Song Collection,” 1870) compiled by Andrius Jonas Vištelis-Višteliauskas (1837–1912) - a poet, publicist, translator, and participant in the 1863–1864 uprising. The manuscript is preserved in the Manuscript Department of Vilnius University Library.
