 Armatus , as magister militum , was sent with all available forces in Asia Minor , to oppose the advancing army of the Isaurians , but secret messages from Zeno , who promised to give him the title of magister militum for life and to confer the rank of Caesar on his son , induced him to betray his master . Armatus avoided the road by which Zeno was advancing and marched into Isauria by another way . This betrayal decided the fate of Basiliscus .
