Santiago de Compostela campaign

The cavalry left Córdoba on 3 July accompanied by supply wagons, along the old Roman road that headed northwest, while the infantry, weapons, provisions and ammunition headed for the port city of Alcácer do Sal, where they would embark to the rendezvous point at the city of Porto, in Portuguese territory.^[3] At Coria, several counts from León joined Almanzor's army.^[4] From there, Almanzor reached Viseu, where he was joined by subjugated counts and Christian nobles exiled from their countries, such as Galindo the Galician or Froila Gonçalves, former count of Coimbra, who had preferred to side with Almanzor when he captured the city in 987.^[3][5]

Once the army and navy had gathered in the Douro River, the troops crossed it via a pontoon bridge that Almanzor had built, the first to connect its two banks.^[6] Porto was poorly fortified and offered little resistance.^[7] The campaign towards Galicia was preceded by an incursion by troops led by a brother of Froila Gonçalves, Veila Gonçalves, who lived in Terra de Santa Maria under Muslim rule and was charged with neutralising any forces that could jeopardise the advance of the Muslim army, namely those of Count Gonçalo Mendes of Portugal.^[5] Henrique Gonçalves, lord of Maia, whose castle was the main fortification in the region, colluded with Veila.^[5][8] Henrique Gonçalves also took advantage of the occasion to usurp the land of Dona Zalamiz and her son Didago.^[8] Braga was besieged with difficulty but it was ultimately sacked and destroyed.^[9][7] Brittonia, near Viana do Castelo, put up strong resistance but was sacked.^[7] At Valadares de Monção, they crossed the Minho river.^[3]

North of the Minho, the castle of San Pelaio was razed to the ground.^[3] Iria Flavia was sacked and destroyed.^[4] Throughout western Galicia, numerous towns and monasteries were destroyed.^[3]

When the first messengers reported the approach of the Cordovan army, the Bishop of Compostela, Pedro de Mezonzo, ordered the evacuation of the city and withdrew to a monastery in the interior, possibly in Sobrado, along with the saints relics on this occasion, it is assumed.^[10] Almanzor's army pitched camp outside Compostela on 10 August.^[10] The city was sacked and razed to the ground, but Almanzor decided to spare the tomb of St James the Apostle, and the guards he posted prevented it from being damaged.^[10][11] Almanzor remained in Santiago de Compostela for eight days.^[10] During his stay, he demolished the cathedral, the monastery of San Martín Pinario, the hospital founded by Sesnando II, the monastery of Antealtares and all the temples and palaces in the city.^[10]

On their way back from Santiago, the spoils were divided at Lamego among the leaders who had taken part in the campaign, both Christian and Muslim.^[7] Almanzor installed a Muslim garrison in Zamora, but the bulk of his troops remained in Toro.^[12][13] Almanzor then imposed peace terms on the Christian lords that allowed him to renounce campaigns in the north in 998, the first year this had happened since 977.^[13] Almansor's army was struck by dysentery during its march to Cordoba.^[14] Among the spoils captured in Santiago de Compostela were the bells and doors of the cathedral, carried by 4,000 captives taken during the campaign.^[15] The bells were turned into chandeliers for the great mosque of Córdoba.^[16][17]

Two years after Almanzor's attack, Bishop Pedro de Mezonzo restored the temple of Santiago.^[15] Almanzors attack in 997 had profound repercussions. Santiago de Compostela became an important international pilgrimage destination over the following century and a symbol of Christianity in the Iberian Peninsula.^[16] Santiago, in turn, was gradually adopted as the patron saint of the Reconquista with the epithet the Moor-Slayer.^[16]
