The Medford Public Library is co-sponsoring the online program “Codes and Ciphers in the American Revolutionary War” led by education coordinator for Historic New England. Codes, ciphers, and all manner of methods have been used for hundreds of years to secretly send messages. This program explores some of the devices and codes that were used during the American Revolutionary War, as well as the spies that would utilize them.
