Trajan's Dacian Wars - The Second War

The Second War

Following the first war, Decebalus complied with Rome for a time, but was soon inciting revolt among tribes against them and pillaging Roman colonies across the Danube. True to his intrepid and optimistic nature, Trajan rallied his forces in AD 105 for a second war.

Like the first conflict, the second war involved several skirmishes that proved costly to the Roman military. Faced with large numbers of allied tribes, the legions struggled to attain a decisive victory, resulting in a second temporary peace. Eventually, goaded by the behavior of Decebalus and his repeated violations of the treaty, Rome again brought in reinforcements, took the offensive and prevailed in 105. The next year they gradually conquered the mountain fortress system that surrounded the Dacian capital, Sarmisegetusa. The final decisive battle took place near the walls of Sarmisegetusa, during the summer of 106, with the participation of the legions II Adiutrix and IV Flavia Felix and a detachment (vexillatio) from VI Ferrata.

The Dacians repelled the first attack, but the Romans, helped by a treacherous local nobleman, found and destroyed the water pipes of the Dacian capital. Running out of water and food the city fell and was razed. Decebalus fled, but was followed by the Roman cavalry and committed suicide rather than submit. Nevertheless, the war went on. Thanks to the treason of a confidant of the Dacian king, Bicilis, the Romans found Decebalus's treasure in the river of Sargesia/Sargetia - a fortune estimated by Jerome Carcopino at 165,500 kg of gold and 331,000 kg of silver. The last battle took place at Porolissum (Moigrad).
