In 358 the future emperor Julian met, in Tongeren, a delegation of Salian Franks who had recently settled in Toxandria (the modern Campine region), to the north of Tongeren. They wanted peace but spoke "as if the ground they had seized were rightfully their own". Julian gave ambiguous replies and then after the meetings sent a surprise attack along the Maas or Meuse river, and "they met him with entreaties rather than with resistance, he received the submission of them and their children". They became increasingly important after this time. Zosimus reports that Julian used them as part of his forces in fights against other Germanic tribes.
