Much later, King Richard was to meet his end fighting against Aimar's successor his son Guy, when buried treasure on Limoges land was in dispute and claimed by Richard (J. Gillingham "Richard I"). The Duke was besieging the Chateau de Chalus-Chabrol, a small and scantily garrisoned castle in Limousin, France under the control of Aimar, when he was shot by a crossbow, possibly fired by a certain Pierre Basile. Richard was hit in the shoulder and died days later on April 6, 1199. Aimar is most famously known for being a fulcrum of insurrection against his liege, Richard the Lionheart, who was a noble frenchman from Anjou and rightful Duke of Aquitaine after his mother Eleanor. Aimar, like many of the fractious Aquitanian nobles, participated in sporadic rebellions against ducal authority throughout his adult life, often co-operating with Duke Richard's brothers, the Count of Angouleme and the house of Lusignan, though he was generally brought to heel.
