The Gallic emperor besieges and captures Moguntiacum, and puts Laelianus to death, but Postumus' troops seek to sack the city.

Postumus forbids it, as it is part of his own territory, whereupon the troops, enraged and out of control, mutiny and kill him.

One Marius, elevated to imperial rank by his comrades, is the summer or autumn of 269 strangled due to private quarrel.

Postumus' colleague Marcus Piavonius Victorinus, a former tribune in the Praetorian Guard who had perhaps been joint emperor, succeeds him.
