Timeline of events

The size of the Roman army amassed against the rebels was much larger than that commanded by Titus sixty years earlier - nearly one third of the Roman army took part in the campaign against Bar Kokhba. It is estimated that forces from at least 10 legions participated in Severus' campaign in Judea, including Legio X Fretensis, Legio VI Ferrata, Legio III Gallica, Legio III Cyrenaica, Legio II Traiana Fortis, Legio X Gemina, cohorts of Legio V Macedonica, cohorts of Legio XI Claudia, cohorts of Legio XII Fulminata and cohorts of Legio IV Flavia Felix, along with 30–50 auxiliary units, for a total force of 60,000–120,000 Roman soldiers facing Bar Kokhba's rebels. It is plausible that Legio IX Hispana was among the legions Severus brought with him from Europe, and that its demise occurred during Severus' campaign, as its disappearance during the second century is often attributed to this war.
