Masha Rolnikaitė kept a diary from 1941 to 1945, from the beginning of the occupation of Lithuania by German troops until her liberation on March 10, 1945.
First in the Vilnius ghetto, then in labor concentration camps in Strazdenhof (Riga, Latvia) and Stutthof (Poland).
Her diary is less known, but no less significant than Anne Frank's diary.
Some parts of the diary Masha managed to write down, but most of it she kept "in her mind," memorizing it.
The complete text of the diaries was recorded by her in 1946, already in Vilnius, and was first published there, but only in 1963, during the "thaw," in Lithuanian.
