Japanese spy game (Le Jeudi de la jeunesse, Dec. 8, 1904)

Bottom right:

Game rules: This game is played by two players. One takes in hand the six pieces representing the Russians, and the other the one representing the Japanese spy (small piece on the right).
At the start of the game, the six Russians are placed in the six squares surrounding the Port-Arthur enclosure, and the Japanese spy in one of the four squares at the bottom of the game.
The aim of the spy is to enter Port Arthur, and that of the Russians is to prevent him from doing so, to surround him on all sides and make it impossible for him to leave the circle they must form around him; if the spy manages to enter Port Arthur, he has won the game; if the Russians surround him, as mentioned above, they are the winners.
The pawns can move forward, backward, to the right or to the left, as the players wish; each pawn can only move one square forward with each move.
The spy must change square with each move; also with each move, one of the Russian pawns, the one that suits the player, must change square. You move from one square to another by the sides, never by the corners.
