Titus Labienus
Titus Labienus, the commander of the Fourth legion, which was stationed in the southern Ardennes, discovered that Indutiomarus and the Treveri were rebelling as well. The Treverian leader called for aid from the Senones and Germanic tribes east of the Rhine. The Fourth legion withstood the siege and Indutiomarus was killed after an unsuccessful attack. His relatives made their escape across the Rhine.
