In 1940 , Nirenska learned that more than 75 members of her extended family had died in The Holocaust . Her parents and brother escaped death by fleeing to Mandatory Palestine . For the next six years , she danced extensively for military personnel and for the Polish government-in-exile , but choreographed no new pieces . Feeling that audiences had too much tension and tragedy in their lives , she only performed in light-hearted pieces during the war . She also danced in the 1942 revue '' Waltz Without End '' at the Cambridge Theatre in 1942 . Nirenska later said that she danced more frequently during the war than at any other time in her life
