Yesterday, we remembered a dark day in American history and commemorated the sacrifice of more than 2,000 service members. On December 7, 1941, Japanese planes launched a surprise aerial attack on Pearl Harbor and killed over 2,000 service members, leading our nation into WWII.

The tragedy of that Sunday morning in Hawaii back in 1941 provides a solemn reminder of the risk and sacrifice our service members make — even when we're not at war.

To remember our heroes in uniform who served at Pearl Harbor and in WWII, we have created a quiz to give you a chance to learn more about this pivotal moment in history. Will you take our quiz now to test your knowledge of Pearl Harbor?

How many U.S. ships did the Japanese destroy or significantly damage during the attack on Pearl Harbor?

Thanks for taking time to learn more about this important day — and for all you do to support our heroes in uniform.
