October 800 – 3 April 801 (French Wikipedia); English Wikipedia also gives 4 April 801
From 20 August 800 to April 801, Louis the Pious led the Carolingian conquest of Barcelona (Madinat Barshiluna), held for about eighty years by the Emirate of Córdoba. A considerable army from Aquitaine, Gascony, Burgundy and Gothia, with many siege engines, was divided into three corps (French/English Wikipedia): Rostany, count of Girona, invested the city from October 800; William of Gellone and Adhemar of Narbonne stood between Lleida and Zaragoza to block Córdoban relief; Louis protected the Roussillon valley. Wali Sadun al-Ruayni left to seek help, was discovered and captured (then probably sent to Aachen); Harun took over. During winter 800–801 William and Adhemar besieged and ravaged the areas of Lleida and Huesca; westwards a Pamplona revolt served as diversion. Louis arrived in February 801 for the final phase. On 3 April 801 (4 April per English Wikipedia), Harun agreed to surrender the city worn out by hunger, privation and wartime strain; the inhabitants opened the gates. Solemn entry of Louis. Bera, leader of the Gothic contingent, became the first count of Barcelona. Important correction: the strengths “non chiffré (Wikipedia) / 3–5,000” sometimes reused here are not Wikipedia primary figures and are withdrawn in favour of the sourced wording alone (“considerable army”, siege engines). French Wikipedia clarification: Sadun al-Ruayni was captured seeking relief; Harun capitulated on 3 April 801. Strengths “non chiffré (Wikipedia) / 3–5,000” not retained (not Wikipedia primary).
