The Franks, the Longiones, and the Vandals,…

The Franks, the Longiones, and the Vandals, despite their huge numbers, have all been defeated within two years.

At one point, Probus had captured the leader of the Longiones, called Semnon, and upon Semnon's acceptance of terms permitted his return to his homeland with his surviving people.

At one occasion during these successful campaigns, sixteen German chiefs are said to have knelt at Probus' feet.

Hostages are taken to ensure the peace and some sixteen thousand Germans are recruited into the Roman army.

In 279, the emperor sets out for Syria, desiring to reconquer Mesopotamia from Sassanid Persia.
