About Siege of Paris, from BoardGameGeek:

A game inspired by the Prussian siege of Paris. The game is played on a 12x16 grid which has a fortress in the center consisting of eight circular spaces. Thirty-six attackers, eighteen from each end of the board, attempt to immobilize the eight defenders in the fortress. The defenders win by capturing all besieging soldiers and six officers. The attackers draw by entering the fortress or win by having an officer and two or three men in the fortress.
