Some Bielski partisans ( but not the Bielski brothers themselves ) have been accused of war crimes against the neighboring population , particularly of involvement in the 1943 Naliboki massacre of 129 persons , committed by Soviet partisans . Though some witnesses and historians place Bielski partisans at the massacre , former members and other historians such as Bogdan Musiał dispute this , stating that the partisans did not arrive in the area until several months later . Musiał notes that some Bielski partisans stole food from the massacre 's survivors
