For a few years, the Fatimids continued to launch attacks from Barqa into Egypt: in 922 and 928, Fatimid troops fought Abbasid troops at Dhat al-Himam, some 60 kilometres (37 mi) west of Alexandria, while in 923, another Fatimid commander raided one of the oases of the Western Desert (likely Dakhla Oasis) and laid waste to it, before the outbreak of a disease forced him to retreat.[24]
