Onslaught

AD 69: The Rhine frontier has exploded into bloody rebellion, and four centurions who once fought in the same army find themselves on opposite sides of a vicious insurrection. The rebel leader Kivilaz and his Batavi rebels have humbled the Romans in a battle they should have won. The legions must now defend their northern stronghold, the Old Camp, from the enraged tribes of Germany, knowing that they cannot be relieved until the civil war raging to the south has been resolved. Can they defend the undermanned fortress against thousands of barbarian warriors intoxicated by a charismatic priestess's vision of victory?
