Which Roman Legion crucified Jesus?

Jesus was not crucified by a Roman legion; legions were made up of 8,000 Roman soldiers that were also Roman citizens. Legions were standing armies that were mobilized in times of war. In Judea, the country in which Jesus was crucified, the Roman Empire had already handily besieged the country about 100 years prior; there were no wars being fought in the region and thus there were no legions in Judea. The armed unit that crucified Jesus was an auxiliary unit called Cohors I Sebastenorum. It should be noted that auxiliary units, otherwise known as Cohorts, were made up of 800 non-Roman soldiers who provided military support to the Legions themselves. Cohors I was an armed unit of palace guards and cavalrymen that was founded by Herod the Great, king of Judea, before his death which occurred approximately 34 years prior to Christ’s crucifixion. Pontius Pilate and his palace were protected by Cohors I which was still a functioning military unit. It is a common misperception that Cohors I was an Italian/Roman unit. The soldiers that protected the prefect were actually Samaritans from Samaria, Northern Israel, that were enlisted to protect the Prefect in Judea, Southern Israel. The practice of stationing soldiers a sizeable distance away from their hometown was done to decrease the chance of the soldiers ever revolting. Cohors I was trained in all aspects of military combat including capital punishment and crucifixions.
