Bykaŭ's literary achievement lies in his sternly realistic, albeit touched by lyricism, depictions of World War II battles, typically with a small number of characters. In the ferociousness of encounter they face moral dilemmas both vis-a-vis their enemies and within their own Soviet world burdened by ideological and political constraints. This approach brought vicious accusations of "false humanism" from some Red Army generals and the Communist Party press.
