Servius Sulpicius Galba joined forces with Lucius Licinius Lucullus and together started to depopulate Lusitania. While Lucullus invaded the country from the east, Galba attacked it from the south. Unable to sustain a war on two fronts, the Lusitanian troops suffered several losses in engagements with the Romans. Fearing a long siege and the destruction the Roman siege engines would cause in their towns, the Lusitanians sent an embassy to Galba to negotiate a peace treaty, although for the Romans it would be perceived as the "Deditio in dicionem", the surrender. The Lusitanians hoped they could at least renew the former treaty made with Atilius. Galba received the Lusitanian embassy politely, and a peace treaty was agreed on the terms proposed by him. He commanded them to leave their homes and remain in open country. The Lusitanians probably lost their city and possessions and their land would have become "Ager Publicus". The conquest of a territory, unless it had been given special conditions, could imply the acquisition, by the Romans, of the conquered territory and all that it contained.
