jan 1, 1882 - The American Kriegsspiel Published
Description:
From William H. Livermore, this game notes in the beginning piece that it had changed significantly in the 13 years since it appeared. It should be noted that the English version of Kriegsspiel was not officially translated to English until 1879 so i'm unsure about this assertion.https://www.loc.gov/item/18012445/
