Final answer:
Acts of heroism during World War II included Irena Sendler saving 2,500 children, Oskar Schindler's protection of Jewish workers, the defiance of Loukas Karrer and Dimitar Peshev, as well as courageous military actions in key battles like Normandy and the Battle of the Bulge.
Step-by-step explanation:
Throughout World War II, there were countless acts of individual heroism by members of the Allied forces and civilians. Notable examples include Irena Sendler, a member of the Polish Underground Resistance who saved approximately 2,500 Jewish children by smuggling them out of the Warsaw ghetto. Oskar Schindler, a German industrialist and member of the Nazi Party, boldly saved the lives of over one thousand Jewish workers by employing them in his factory and protecting them from Nazi persecution. Additionally, Loukas Karrer, the mayor of Zakynthos, and Dimitar Peshev of Bulgaria displayed immense courage and defiance against the Nazis, resulting in the preservation of thousands of Jewish lives. In a military context, the heroism of troops such as those involved in the Battle of Normandy and the 761st Tank Battalion during the Battle of the Bulge were pivotal in securing victories for the Allies.
Valor on the home fronts was also significant, with figures such as Jimmie Stewart and Josephine Baker contributing both on and off the battlefield by serving in the armed forces and aiding in morale and resistance efforts respectively.
