In 52 BC, during the Gallic Wars, the Roman army of Julius Caesar besieged the Gauls' leader Vercingetorix in the oppidum (fortified settlement) of Alesia.
The basic concept of the game is the double siege, with Roman lines facing both inwards around Alesia, and outwards against Gallic relieving forces.
[2] In his 1977 book The Comprehensive Guide to Board Wargaming, Nicholas Palmer called the original amateur edition by Robert Bradley "much admired."
He warned that despite the Gauls' huge advantage in numbers, "inspired leadership give the Romans a fair chance despite a 6–1 numerical inferiority."
"[3] In his 1980 sequel, The Best of Board Wargaming, Palmer added "One of the most original games ever designed, with a strong flavour of the tactical situation facing Julius Caesar."
Berg liked that Roman troops cannot defend everywhere at once, and noted that because of that, "the game soon becomes a fierce struggle of sudden attacks and well-thought-out strategies."
