If your knowledge of Native Americans serving in the U.S. military begins and ends with Johnny Cash’s rendition of “The Ballad of Ira Hayes,” you’ll learn more at the National Museum of the American Indian’s new exhibition. A series of placards with text and photos, Patriot Nations: Native Americans in Our Armed Forces, includes the feel-good Civil War story of Ely S. Parker, a Seneca Indian and the highest-ranking Native American in the Union Army, who drafted the terms of surrender as Ulysses S. Grant’s secretary. Another placard is devoted to Hayes, a Pima Indian serving in the U.S. Marine Corps in World War II, who was among the Marines raising the American flag over Iwo Jima in the famous Associated Press photograph.

Saturday: Carl Maria Von Weber‘s 1821 opera Der Freischütz (The Marksman, or in Virginia Opera’s version, The Magic Marksman) didn’t have the lasting power of The Ring Cycle or The Flying Dutchman or any of his proto-fascist successor’s great works, but it set the stage for a lot of them with its basis in German folklore, supernatural elements, and use of motif. It tells the story of a fool in love who unwittingly makes a deal with the devil to win a shooting contest with magic bullets, thereby securing the affection of his crush.
