Enigma Machine - Enigma Machine During World War II, the Germans used the Enigma, a cipher machine, to develop nearly unbreakable codes for sending messages. The Enigma's settings offered 150,000,000,000,000,000,000 possible solutions, yet the Allies were eventually able to crack its code. By end of the war, 10 percent of all German Enigma communications were decoded at Bletchley Park, in England, on the world’s first electromagnetic computers.
1864 American (Pennsylvania) Side drum at the Metropolitan Museum of Art, New York - From the curators' comments: "This side drum from the 1860s bears a stenciled eagle design that was typical of the thousands of instruments produced for use by the Union army during the Civil War. The eagle is painted on a blue field, which means it was used in the Infantry, and a banner held in the eagle's beak bears the words REG: U.S. INFANTRY."
