On the morning of December 7, 1941, Imperial Japan launched a surprise attack on Pearl Harbor which left more than 2,400 American personnel dead in just 90 minutes of fighting. Seventeen ships were damaged or lost, including the USS West Virginia (top left). On the ground, 188 aircraft were destroyed and 156 damaged (top right and bottom left). Just eight pilots managed to take off during the assault, and six were credited with shooting down at least one Japanese. While the assault was an initial success, it dragged America into the Second World War and ultimately led to Japan's defeat as nuclear bombs were dropped on the cities of Nagasaki and Hiroshima.
