From Pearl Harbor to the Atomic Bomb, from D-Day to Iwo Jima, and from the Nazis to the Holocaust, World War II was the most catastrophic event of the 20th century. This series examines the roots of the war, the epic battles and key campaigns, the technology and weapons used, the military and political leaders, and the ordinary men and women who lived-and died-during these tumultuous times. Maps, quotes, and historical photos help readers understand the struggle that defined a generation and changed the face of history. Abdo & Daughters is an imprint of Abdo Publishing, a division of ABDO.
