"The Siege of Bayonne was launched by Alfonso the Battler, King of Aragon and Navarre, apparently against the Duke of Aquitaine, William X, and lasted from October 1130 to October 1131. The city of Bayonne was then a part of Aquitaine, nominally a part of France. The chief narrative source for the siege of Bayonne is the Chronica Adefonsi imperatoris, a contemporary account of events in Spain compiled to celebrate the feats of Alfonso VII of Le\u00F3n and Castile."@en .
