Other Normans now flocked to the land of promise. Among these was a chieftain named Ranulf, who joined Sergius, Prince of Naples, a vassal of the Greeks, in his war against the Lombard prince Pandulf of Capua. In reward for his services Ranulf received one of the richest districts of the Terra di Lavoro, where he built in 1030 a town named Aversa, the first Norman settlement in Italy. [Sidenote: Foundation of Aversa, 1030.] This foundation makes a new departure in Norman policy. The Normans no longer came to Italy as isolated adventurers willing to sell their swords to the highest bidder. By much the same arts as those by which their brethren later got hold of the fairest parts of Wales and Ireland, the adventurers strove to carve feudal states for themselves out of the chaos of southern Italy. Whilst cleverly utilising the feuds that raged around them, they pursued their interests with such dexterity, courage, and clear-headed selfishness, that brilliant success soon crowned their efforts. Conrad II. sojourned at Capua in 1038, deposed Pandulf and confirmed Ranulf in the possession of Aversa, which he erected into a county owing homage to the Western Emperor. Three of the twelve sons of the Norman lord, Tancred of Hauteville, now left their scanty patrimony in the Côtentin and joined the Normans in Italy. Their names were William of the Iron Arm, Drogo, and Humphrey. [Sidenote: The sons of Tancred of Hauteville.] In 1038 they joined the Greeks under George Maniaces in an attempt to expel the Mohammedans from Sicily. Messina and Syracuse were captured, but an affront to their companion-in-arms Ardouin drove the Normans back to the mainland in the moment of victory, and led them to wreak their vengeance on the Greeks by a strange compound of violence and treachery. Ardouin their friend took the Greek pay and became governor of Melfi, the key of Apulia. He proposed to the Normans that he should deliver Melfi to them, and make that a starting-point for the conquest of Apulia, which he proposed to divide between them and himself. The northerners accepted his proposals. [Sidenote: Conquest of Apulia, 1041–2.] In 1041 Melfi was delivered into their hands, and a long war broke out between them and their former allies. By shrewdly putting Adenulfus, the Lombard Duke of Benevento at the head of their armies, the Normans got allies that were probably necessary in the early years of the struggle. But they were soon strong enough to repudiate their associate. The divisions of the Greeks further facilitated their task. In 1042 William of the Iron Arm was proclaimed lord of the Normans of Apulia, with Melfi as the centre of his power.
