Following on from the outbreak of the Second World War in 1939, in June 1941 the German Army invaded the Soviet Union. German forces occupied Privolnoye for four and a half months in 1942. Gorbachev's father had joined the Red Army and fought on the frontlines; he was wrongly declared dead during the conflict and fought in the Battle of Kursk before returning to his family, injured. After Germany was defeated, Gorbachev's parents had their second son, Aleksandr, in 1947; he and Mikhail would be their only children.
