Oliver later reported in his chronicle, Historia Damiatina,[2] the sequence of events that followed. In the Holy Land, when King Andrew of Hungary broke off from the crusade in 1218 and returned to Europe, Oliver's Akkon Canton Frisian contingent, which had circumnavigated the Iberian Peninsula and just arrived, persuaded him to continue the crusade by attacking Damietta on Egypt's Nile Delta. In August 1218 the Friesian crusaders distinguished themselves by their success in destroying Damietta's upstream tower, located in the middle of the Nile.
