Ebles is probably a relative of Sancho Ramírez, King of Aragon, both descending from the Dukes of Aquitaine.

Sancho Garcés IV, the ruler of Navarre, and his neighbor, Ahmad al-Muqtadir, the ruler of Zaragoza, conclude an alliance by treaty on May 25 against the planned crusade.

For reasons unknown, the crusade never takes place, or at least leaves no record of its accomplishments, which must in any case have been meager.

According to one historian, the crusade may have been frustrated by Gerald of Ostia, Papal legate, Cardinal and Cluniac, as part of the efforts of the Abbey of Cluny to support the Kingdom of León–Castile in its rivalry with the Kingdom of Aragon.

The Papacy under Alexander and Gregory has supported the Aragones, and at least some of Alfonso VI of Castile's actions in 1073 can be seen as a response to the projected crusade.

The appointment of Gerald, a former grand prior of Cluny, and the archdeacon Raimbald as legates in Spain may have been intended originally by Alexander II to appease Alfonso VI or his predecessor, Sancho II, by assuring them that their claims on the parias of Zaragoza (which, along with allied Navarre, felt threatened by the crusade) were not in jeopardy.

Upon becoming Pope, however, Gregory had removed Gerald from this position and instated Hugh Candidus, a veteran of the crusade of Barbastro and a friend of the king of Aragon.
