Thursday June 6, 2024 is the 80th anniversary of D-Day, the day Allied forces landed on the beaches of Normandy to begin the “great and noble undertaking” of liberating Europe. We commemorate the anniversary with the words of General Dwight Eisenhower, commander of the Allied forces. The introduction that follows, and the words of Eisenhower, are from World War II: Core Documents, selected and introduced by Jennifer D. Keene.
