== Any notability to his writings? == 

    At the risk of personal embarrassment, i'll ask that someone comment on whether he is noted for what he wrote on military strategy: Is our article on him incomplete in failing to mention any titles by him?    (The embarrassment part reflects the impetus for my question:  i quote from the SF novel Ender's Shadow, p. 211 of the "First mass market edition" of Dec. 2000, where a "Command School" instructor says of the title character, one of the students, 
 : "I should have guessed. He picks up the voice of the strategists he's been reading. Or their translators. Though I don't know what will happen now that he's he's [sic] been reading Frederick and Bulow in the original  French and German...." 
 Not a WP:RS!)    The char's presumably reading Frederick the Great (master of Sanssouci) in French and Dietrich Heinrich von Bülow in German. I did find on first try  FREDERICK THE GREAT "MILITARY INSTRUCTIONS" and Frederick The Great On The Art Of War Paperback by Jay Luvaas; are Card's characters referring to French commentaries on what Fritz did, rather than any wisdom he put on paper (in French  as he would apparently have naturally chosen, rather than German)? Or should we suppose that Card is exercising literary license to imagine Fritz having left extended 1st-hand testimony for the ages?•
