The trip to Zaragoza. The army that enters through Roncesvalles and the one that comes from Pertus, passing through Barcelona, meet in Zaragoza. Here is what the sources say: coniungentes se ad supradictam civitatem ex utraque parte exercitus. (Annales Regii). The armies of both sides gathered in that city. Coniunxerunt autem se uterque exercitus ad Caesaraugustam munitissimam urben. (Annales Mettenses priores). The two armies met in Zaragoza, a solidly fortified city. Inde Hiberum amnem vado traiiciens, Caesaraugustam praecipuan illarum partium civitatem accesit. (New Annales Regii). Cross the Ebro and advance through the neighborhoods of Zaragoza. The account of the first branch of the Karl-Magnon saga mentions that after Roland had taken Nobles (=Pamplona), the Emperor of Rome besieged the town of Montgardig the following day, and that the king having come from Kordè to the aid of the latter, Charles made him flee and, having taken Montgardig, immediately seized Kordè where he killed the sovereign, and finally arrived in front of Zaragoza. Professor Aebischer comments: now, Montgardig = Montjardèn; Kordè = Cordères = Cortes, Tudela and Zaragoza. If we add to these names Tuela and Valterne, which are, without a doubt, Tudela and Valtierra (?), we have a series of clues suitable for marking out the path followed by Charlemagne Pamplona and Zaragoza. Without a doubt, we are not in history, but in legendary history, in epic legend; but who would dare maintain that the latter totally excludes the former (Textes norrois... pp. 57-58). Abadal rightly assumes that in Barcelona the Frankish expeditionaries were joined by their wal Sulaiman al-Arabi. The expedition continued along the road through Lérida to Huesca, and there they were joined by the wal of the city, Abu Thawr (Abutauro), and then together they went down to Zaragoza. The Muslim chronicler Ibn al-Athir says that Sulaiman went out to meet Charles and went with him to Zaragoza; but al-Hussain ibn Yahya al-Ansari, a descendant of Jaad ibn Obaida, overtook him in power and opposed Sulaiman.
