Early predecessor of Stratego. Designed by Mademoiselle Hermance Edan, who filed a patent for a 'jeu de bataille avec pièces mobiles sur damier' (a battle game with mobile pieces on a gameboard) on 26 Nov 1908. The patent was released by the French Patent Office in 1909 (patent #396.795 [6]). Hermance Edan had given no name to her game, but a French manufacturer named "Au Jeu Retrouvé" was selling the game as L'Attaque as early as 1910."
The game is played with 36 pieces each on a 9x10 square board. Each piece has a numeric value, which is hidden from the opponent and only revealed when an attacking piece moves onto a square occupied by an opponent's piece. In most cases, the piece with the highest value wins and the losing piece is removed from the board.
Play continues until one player finds the opponent's flag piece and takes it.
