What Have We Learned, Charlie Brown? A Tribute is the 26th prime-time animated television special based upon the comic strip Peanuts, by Charles M. Schulz, who introduced the special. It originally aired on the CBS network on May 30, 1983, Memorial Day in the United States, and one week prior to the 39th anniversary of the D-Day Invasion. It was rebroadcast on CBS on May 26, 1984 and again on May 29, 1989. Production The special directly follows the events of the 1980 theatrical feature film Bon Voyage, Charlie Brown (and Don't Come Back!!). Charlie Brown, Linus, Snoopy, Peppermint Patty, Marcie, and Woodstock are returning from their student exchange in Paris. The film was purposefully open-ended in case there could be other adventures among the characters prior to returning home. Charles Schulz said about its development, Schulz struggled with development of the storyline until shortly after his open-heart surgery in 1981. While recuperating, he was able to finalize the concept with a common line that would tie everything together, "What Have We Learned, Charlie Brown?" Plot The special opens with Charlie Brown at home and he takes a book from his shelf titled "My Trip". His younger sister, Sally, approaches and asks him what he's doing. Charlie Brown tells her that he's making a photo album with pictures he took in France when he, Linus, Peppermint Patty, Marcie, Snoopy, and Woodstock went there for a student exchange. Sally realizes that Charlie Brown never told her what happened after the fire in the chateau and how he got home and asks if he learned anything. From there, it is shown in a flashback: As they begin to head back from the chateau to the train station for the return trip to London (where they would return to America by plane), their problematic rental car (a Citroen 2CV) slows their progress, before breaking down entirely in a small French town. Renting another one from a French lady (who immediately accepts their offer after realizing Snoopy is, in fact, a World War I Flying Ace) they soon become lost and camp at a nearby beach for the night. Linus, however, wakes up shortly before daybreak and walks along the beach, realizing they are at Omaha Beach. Linus then tells of the battle of D-Day, leading the group to the nearby cemetery for all of the American soldiers. The voice of General Dwight D.
