The army was probably sent in 552 and made landfall in June or July. Roman forces landed probably at the mouth of the Guadalete or perhaps Málaga and joined with Athanagild to defeat Agila as he marched south from Mérida towards Seville in August or September 552.[8] The war dragged on for two more years. Liberius returned to Constantinople by May 553 and it is likely that a Byzantine force from Italy, which had only recently been pacified after the Gothic War, landed at Cartagena in early March 555 and marched inland to Baza (Basti) in order to join up with their compatriots near Seville.
