, 1638|280x280px Sertorius crossed the strait at Gibraltar at Tingis in 80 BC, landing at
Baelo near the
Pillars of Hercules in the summer or fall of the year. A small fleet under an
Aurelius Cotta (specific name not known) from the coastal town of
Mellaria failed to stop him. After being reinforced by the Lusitanians he marched on Lucius Fufidius,
propraetor of Hispania Ulterior, and defeated him at the
Battle of the Baetis River, consolidating control over the province. News of Sertorius' victory spread throughout Hispania Ulterior, including a rumour that his army included fifty thousand cannibals.
Lusitania and Lacobriga The Senate learned that Sertorius had returned to Hispania, and as a result sent
Quintus Caecilius Metellus Pius, an experienced Sullan general, with a proconsular command by the Senate specifically to defeat and drive him from Hispania Ulterior. Metellus would be Sertorius' main antagonist between 80–77 BC. Prior to Metellus' arrival,
Marcus Domitius Calvinus, proconsul in Hispania Citerior, marched against Sertorius but was defeated by
Lucius Hirtuleius, Sertorius' legate. Sertorius, who referred to Metellus as "the old woman", employed guerrilla warfare effectively and outmaneuvered Metellus through rapid and relentless campaigning. Sertorius also defeated and killed
Lucius Thorius Balbus, Metellus' legate. Although initially outnumbered, Sertorius' repeated victories, along with his "uncharacteristically humane" administration impressed the native warriors, many of whom joined his cause. His character, in that he treated the natives as allies rather than subjects, may have also played a role. Sertorius organized the natives into an army and adjoined them to his core Roman forces, commanding them under Roman officers. The natives are said to have called Sertorius the "new
Hannibal" whom he resembled physically (having one eye) and, they believed, in military skill. ,

This was likely partially pragmatic, as Sertorius had to retain the goodwill of the native Iberians if he had any chance of winning the war. Sertorius' most famous strategy to this end was his white fawn, a present from one of the natives that he claimed communicated to him the advice of the goddess
Diana, who had been
syncretized with a native Iberian deity. The Iberians were greatly impressed by the fawn, who was calm in Sertorius' military camp and affectionate with him, and saw Sertorius as a divinely favoured leader. Sertorius would obscure information from military reports, claim Diana had told him of said information through the fawn in his dreams, and then act accordingly to further this belief. White animals were perceived as having oracular qualities among Germanic peoples, and in Hispania itself there existed a stag cult of
funerary and oracular nature; this cult was most popular in western Hispania and Lusitania, where Sertorius drew his most fervent followers. As a result of all of these factors, Sertorius' power and army grew exponentially in 80 and 79 BC. Sertorius gained control over both Hispanian provinces with the aid of Hirtuleius in 79 BC despite Metellus' efforts. From 78 BC onward Metellus campaigned against Sertorian cities, but Sertorius thwarted his invasions into Lusitania and Ulterior. When Sertorius learned of Metellus' intention to siege
Lacobriga, Sertorius supplied the city in response, and then prepared to meet Metellus there. When Metellus arrived and sent out foragers, Sertorius ambushed them and killed many, forcing Metellus to leave, unsuccessful. In 77 BC, Sertorius focused his attention on subduing Iberian tribes who had not yet accepted his authority in the interior. Metellus did not extensively campaign against Sertorius in the year due to the revolt in Rome of the consul
Marcus Aemilius Lepidus (father of the
triumvir). At some point during these years, Sertorius challenged Metellus to
single combat, and when Metellus declined, his soldiers mocked him. . The drawing illustrates the example Sertorius gave to his followers that in the same way a horse's tail can be picked out hair by hair but not pulled out all at once, so smaller forces could defeat the Roman armies.Sertorius made the Iberians an organized army through Roman formations and signals. He encouraged them to decorate their armaments with precious metals, thus making them more likely to retain their equipment between engagements. Many native Iberians pledged themselves to him, serving as bodyguards who would take their own lives if he perished. Famously, while organizing his armies, the natives under Sertorius' command wanted to take on the Roman legions head-on. Unable to convince them otherwise, he allowed the natives to do so in a minor engagement. Afterward, he had two horses brought in front of them, one strong, the other weak. He ordered an old man to pull hairs from the strong horses' tail one by one, and a strong youth to pull on the weak horses' tail all at once; the old man completed his task, while the youth failed. Sertorius then explained that the Roman army was similar to the horse tail, in that it could be defeated if attacked piece by piece, but if taken all at once victory was impossible.
Contrebia and Lauron In the summer of that year, with Lepidus' revolt having ended, the Roman Senate recognized a greater force was needed to defeat Sertorius, as to this point all Sullan generals had been defeated or killed and Metellus had proven to be no match for him. By the 76 BC campaigning season, Pompey had recruited a large army, some 30,000 infantry and 1,000 cavalry from his father and Sulla's veterans, its size being evidence of the threat posed by Sertorius to the Sullan Senate. His arrival in Hispania stirred up rebellious sentiments against Sertorius in the peninsula, due to Pompey's reputation as a skilled general. Sertorius paid close attention to Pompey's movements despite his open contempt toward the younger general, who he called "Sulla's pupil". Sertorius was now at the height of his power, as near all of Iberia was under his control and he had several large armies throughout the peninsula with which to combat the Roman generals. Sertorius, apparently, did not intend to march on Pompey or expect him to offer battle. In 75 BC, Perperna and Herennius were defeated at the
Battle of Valentia by Pompey. Hearing this, Sertorius left the command against Metellus with Hirtuleius and marched his army to meet Pompey. Metellus defeated Hirtuleius at the
Battle of Italica, so Sertorius sent Perperna at the head of a large army to block Metellus from coming to Pompey's aid and engaged Pompey, who, for whatever reason, chose to accept the offer of battle rather than wait for his ally, beginning the
Battle of Sucro late in the day. Each general took the right flank; Pompey faced a Sertorian legate, while Sertorius faced
Lucius Afranius. When Sertorius saw his left wing falling to Pompey, he rallied them and led a counterattack which shattered the Pompeian right, nearly capturing Pompey himself. Afranius, however, had broken the Sertorian right and was plundering their camp; Sertorius rode over and forced Afranius to depart back to Pompey. Both armies drew up again the next day, but Sertorius then heard Metellus had defeated Perperna and was now marching to aid Pompey. Unwilling to fight two armies who would outnumber him if joined, Sertorius decamped, bitterly commenting: Sertorius negotiated with King Mithridates VI of Pontus during his war, likely in the winter of 75 BC. Mithridates wanted Roman confirmation of his occupation of the Roman Province of
Asia, after relinquishing control of it to Sulla in the First Mithridatic War, along with the Kingdoms of
Bithynia and
Cappadocia. Sertorius assembled his Senate to discuss the issue, and decided that Mithridates could get Bithynia and Cappadocia (and possibly
Paphlaglonia and
Galatia as well) as they were kingdoms that "had nothing to do with the Romans". But Asia, being a Roman province, would not be allowed to be his again. Mithridates accepted these terms and sent 3,000 talents of gold and forty ships to Hispania; in return, Sertorius sent the general Marcus Marius and other soldiers to Pontus. (1849).Sertorius was eventually forced by his native troops to give battle against Metellus and Pompey, likely when Metellus marched on the Celtiberian town of Segontia. The coming
Battle of Saguntum was the last pitched battle Sertorius fought, the largest battle of the war, and probably one he had not wanted in the first place. The fighting lasted from noon until night-time and resulted in the deaths of
Gaius Memmius and Hirtuleius. Though Sertorius defeated Pompey on the wing, Metellus again defeated Perperna. The battle ultimately ended in a draw, with heavy losses for both sides. Following the battle Sertorius disbanded his army, telling them to break up and reassemble at a later location rather than organizing a concerted retreat, for fear of Metellus' pursuit. This was common for Sertorius, who "wandered about alone, and often took field again with an army... like a winter torrent, suddenly swollen".
Clunia and the final years After the battle Sertorius reverted to guerrilla warfare, having lost the heavy infantry Perperna had lent to his cause which enabled him to match the Sullan legions in the field. He retired to a strong fortress town in the mountains called
Clunia. Pompey and Metellus rushed to besiege him, and during the siege, Sertorius made many sallies against them, inflicting heavy casualties. Sertorius convinced Metellus and Pompey that he intended to remain besieged, and eventually broke through their lines, rejoined with a fresh Sertorian army, and resumed the war. The two Roman generals had pursued Sertorius into unfriendly lands and thus Sertorius regained the initiative. For the rest of the year he resumed a guerrilla campaign against them, eventually forcing Metellus and Pompey to winter out of Sertorian-aligned land due to lack of resources. During that winter, Pompey wrote to the Senate for reinforcements and funds, without which, he said, he and Metellus would be driven from Hispania. Despite being weakened, Sertorius was still perceived as a threat, as in Rome it was apparently said that he would return to Italy before Pompey did. The Senate capitulated to Pompey's demands; funds and men (two legions) were found with effort and sent to the Roman generals. With the men and materiel reinforcements from Pompey's letter, in 74–73 BC, Pompey and Metellus gained the upper hand. The two Roman generals began slowly grinding down Sertorius' rebellion via attritional warfare. Sertorius lacked the men to meet them in open combat, though he continued to harry them with guerrilla warfare. Mass defections to the Roman generals began, and Sertorius responded to this with harshness and punishments. Sertorius continued to win some victories, but it was by now clear he could not achieve complete victory. The Roman generals continued to occupy strongholds that were once under his control, and Sertorius' support among the Iberian tribes faltered as discontent among his Roman staff rose. Sertorius was in league with the
Cilician Pirates, who had bases and fleets all around the
Mediterranean. Near the end of his war he was also in communication with the insurgent
slaves of
Spartacus in Italy, who were
openly in revolt against Rome. But due to jealousies and fears among his high-ranking Roman officers a conspiracy was beginning to take form. ==Conspiracy and death==
