 The Mobile Column in the south , consisting of the Imperial Camel Brigade , the 11th Light Horse , and the mounted City of London Yeomanry Regiments ( less two squadrons ) , advanced from Ferdan and the <unk> railhead to attack the German and Ottoman left flank , working through Bir El Mageibra , Bir El <unk> and Hod El Bayud . They found Mageibra evacuated on 5 August . After camping there for the night , they fought strong hostile forces between Bayud and Mageibra the following day , but could make no impression . Some days later , on 8 August , the Mobile Column did succeed in getting round the Ottoman flank , but was too weak to have any effect and retired to Bir Bayud .
