Pinkhas Bokshtein was born in 1924 in Moscow. There he finished a ten-year school. Despite being only 17, Pinkhas was drafted into the Red Army on June 23, 1941, the second day of Operation Barbarossa. However, a short time later he was released and joined his parents, who had succeeded in fleeing from Moscow to eastern Kazakhstan. He was drafted for the second time in October 1942. In the first half of 1943, Pinkhas finished a course for drivers of the ZIS heavy truck and, in the summer 1943, was assigned as a military driver and car mechanic to the 8th Company of Trophy [Captured Enemy] Armaments. In this capacity he fought in Belorussia at the end of 1943 (he was wounded in the fall of that year) and in 1944, when he took part in the takeover of Lublin, Poland in July and fought in Latvia and Lithuania. In 1945, he fought in Germany. At the end of the war, Private Bokshtein was awarded the medal For Battle Merit.
During his service in the Red Army both of his parents and his grandfather died in their Kazakhstan evacuation, probably from typhus. Bokshtein blamed the Nazis for their deaths.
Pinkhas Bokshtein was demobilized from the army in 1947 and returned to Moscow, where he worked as an economist. He died in 2002.
