 Before 449 Aetius had signed an agreement with the Huns, allowing some of them to settle in Pannonia, along the Sava River; he also sent to Attila, the king of the Huns, a man called Constantius as a secretary.In 449, Attila was angry over an alleged theft of a golden plate, and Aetius sent him an embassy under Romulus to calm him; Attila sent him a dwarf, Zerco, as a present, whom Aetius gave back to his original owner, Aspar.However, the good terms between Romans and Huns did not last, as Attila wanted to attack Gaul; he knew that Aetius was a serious obstacle to his enterprise, and tried to have him removed, but in 451, when the Huns attacked, Aetius was still the commander of the Roman army in Gaul.
