Revenge and a Revolt
Contributed by David Verne
At the beginning of campaign season, Julianus leads the Roman army across the Danube into Dacia. The Roman push deep into Dacia and meet the Dacian army at the pass of Tapae, the site of their defeat two years ago. To inspire his men, Julianus orders his soldiers to paint their name and their centurion's name on their shield in order to more easily identify legionaries who distinguish themselves in combat. This incentive must have worked because the Romans smash the Dacians, and Decebalus, the Dacian king, begins to build barricades across the road leading to his capital, Sarmizegetusa. Dacian armies begin falling back to defend the capital, and the Romans set up camp for the winter and prepare to besiege the capital in the spring. The Romans were victorious but were delayed by problems on other fronts.
During the winter of 88/89 AD, the governor of the Upper Rhine, Saturninus, had launched a revolt with his two legions. He also paid the Chatti, the German tribe who Domitian had attacked, to help him in the rebellion, which took place during the winter so the Chatti could cross the frozen Rhine. Domitian orders all loyal legions to march on the rebels and crush the rebellion. An unheard of January thaw melted the Rhine and cut Saturninus off from his German allies, and the governor of the Lower Rhine, Lucius Maximus, is able to crush the revolt and execute Saturninus. News of the revolt quickly spread across the northern frontier, and many tribes took advantage of the distraction to raid Roman territory.
