Wanda Wasilewska (Polish pronunciation: ['vanda va?i'l?fska]), also known by Russian name Vanda Lvovna Vasilevskaya (Russian: ??´??? ????´??? ??????´?????) (21 January 1905 – 29 July 1964), was a Polish and Ukrainian Soviet novelist and journalist and a left-wing political activist who became a devoted communist.
She fled the German attack on Warsaw in September 1939 and took up residence in Soviet-occupied Lviv and eventually in the Soviet Union.
She was the founder of the Union of Polish Patriots there and played an important role in the creation of the Polish 1st Tadeusz Kosciuszko Infantry Division.
The division developed into the Polish People's Army and fought on the Eastern Front during World War II.
Wasilewska was a trusted consultant to Joseph Stalin and her influence was essential to the establishment of the Polish Committee of National Liberation in July 1944, and thus to the formation of the Polish People's Republic.
