Summary on the Sea Battle Tafl.
1732 Carl von Linné, Sweden, wrote down in his Lapland excursion diary the rules of the Saami tafl game Tablut.
1811 James Edward Smith, UK, translated the Latin parts of the Linné diary, like the Tablut rules, into English.

1855 Jaques of London, UK, produced the commercial game Imperial Contest, based on the Smith translation. It's identical to our Sea Battle 9x9, except that the king's moves are limited to four squares at once. (Hat tip Damian Walker.)

November 2012 Aage Nielsen (Denmark) drew the dragonship pieces for online Sea Battle tafl.
