King Arthur, subtitled "The Battle of Stonehenge, 536", is a board wargame published by Simulations Publications, Inc. (SPI) in 1979 that simulates the fictional Battle of Camlann between the forces of King Arthur and his son Mordred.
King Arthur is a game representing King Arthur's final battle, where he leads the Knights of the Round Table, with additional mounted knights and archers, against Mordred's alliance of rebel knights, men-at-arms, archers, and slingers from throughout the British isles. The game uses the combat rules from SPI's previously published Great Medieval Battles.
In 1979, SPI published the combat wargame Great Medieval Battles, a "quadrigame" (four separate battles using the same set of rules) that simulated King Arthur's final Battle of Camlann, Robert the Bruce at Bannockburn (1314), The Black Prince at the Battle of Navarette (1367), and Tamburlaine against the Ottoman Turks at the Battle of Angorra (1402).
Later the same year, SPI republished all four of the battles as separate stand-alone games, one of them being King Arthur: The Battle of Stonehenge, 536. The boxed set was designed by Rob and Linda Mosca, with artwork by Redmond A. Simonsen.
Keith Gross reviewed King Arthur in The Space Gamer No. 29.[1] Gross commented that "The game can be fairly playable if the man-to-man combat matrix is replaced with a simple die roll. Overall, King Arthur is not a bad game, but it's not a great one either."[1]
