As Dunkirk arrives in theaters, The Wall Street Journal surveys the cinematic history of the war. 

"Prior to touring the Museum vault with the curatorial staff, our class was introduced to another perspective of teaching World War II—using statistics to help strengthen or challenge an argument."
 

"Out of all the experiences we had Monday, one of the favorite lessons among the teachers was the classroom lesson from the curriculum guide using 'What would you do?' scenarios."

"The lasting lesson from this experience is that men and women throughout our history have sacrificed their lives to protect this nation and protect our freedoms and, for that, we have an obligation as educators to teach about, remember, and honor their sacrifice."

"Being here -- walking on what is sacred ground in the history of a people and a place, talking to those who want to share this with others -- has affected all of us in the most subtle of ways."
