Rome is in turmoil.
Armed mobs rule the streets.
The First Triumvirate, overseers of the last days of the Roman Republic, has disintegrated. In Italy, at the edge of the Rubicon River, word of the stalemate has reached Caesar and his XIII Legion. The great, set-piece battle of the Civil Wars is one of the most famous battles of the ancient world. With both armies virtually wedged between a river and rocky heights, Pompey not only outnumbers Caesar in legions, but his cavalry is far superior to the small mounted force Caesar can bring to bear. Both opponents have several crack legions, but Pompey is forced to use legions of dubious loyalty.
