In return for his help when Roman forces under Publius Cornelius Scipio Africanus and his brother Lucius Cornelius Scipio Asiaticus moved through Macedon and Thrace in 190 BC, the Romans forgave the remaining indemnity that he had to pay and his son Demetrius was freed.
Sebagai balasan bantuannya ketika pasukan Romawi di bawah Publius Cornelius Scipio Africanus dan saudara laki-lakinya Lucius Cornelius Scipio Asiaticus bergerak melintasi Makedonia dan Thrakia pada tahun 190 SM, orang Romawi mengampuni sisa ganti rugi yang harus dibayarnya dan putranya, Demetrius, dibebaskan.
