World War II letters refer to the correspondence exchanged between soldiers, their families, and friends during the conflict from 1939 to 1945. These letters provide personal insights into the experiences of those involved, revealing their emotions, fears, and daily life during the war. They often served as a vital link between soldiers and their loved ones, offering comfort and support amid the chaos. Many of these letters have been preserved and are now valuable historical documents. They help historians and researchers understand the social and emotional impact of the war on individuals and families, as well as the broader context of events like the Holocaust and the D-Day invasion.
