Of course, many of the "barbarians" that are popularly considered inferior soldiers to the Romans challenged and defeated them in open battle on many occasions. Even Sparticus' slave revolt defeated Roman armies in pitched battle (though many of those slaves were captured warriors, so they had distinct advantages compared to most slave revolts).
