When Caesar defeated the Eburones, he invited all of the peoples that were interested to destroy the remainder. The Sicambri responded to Caesar's call. They took large amounts of cattle, slaves and plunder. Caesar commented that "these men are born for war and raids". "No swamp or marsh will stop them". After the raid on the Eburones they moved on against the Romans. They destroyed some of Caesar's units, in revenge for his campaign against them, and when the remains of the legion withdrew into the city of Atuatuca, the Sicambri went back across the Rhine.
