The Battle

Romanian and Serbian forces held the Cerna valley against repeated Central Powers attacks in difficult mountain terrain.

The only historical record of the siege is Trajan's Column, a controversial source primarily as an edilic-artistic work. There is also debate over whether the Romans actually fought to conquer Sarmizegetusa or whether the Dacians destroyed their capital while retreating before the advancing legions. Most historians agree, however, that a siege of Sarmizegetusa did take place. The first attack was repelled by the Dacian defenders. The Romans bombarded the city with their siege weapons and, at the same time, constructed a platform to facilitate entry into the city. They encircled the city with a circumvallation wall. Eventually, the Romans destroyed the water supply of Sarmizegetusa and forced the Dacians to surrender before setting fire to the city. Roman forces succeeded in entering the Dacian sacred area, where they hailed Trajan as emperor and then levelled (destroyed) the entire city.
