 It became apparent that the German and Ottoman right column , ( 31st Infantry Regiment ) was attempting a frontal attack on redoubts held by infantry in the 52nd ( Lowland ) Division . The defenders were able to hold on , but were subjected to severe artillery shelling during the day . <unk> attacks began with heavy German or Austrian fire by their artillery which attempted to breach the infantry defensive line . About 08 : 00 , attacks were being made on Numbers 4 and 5 redoubts which began with heavy artillery fire , but the attacks broke completely when the 31st Ottoman Infantry Regiment were within 150 yards ( 140 m ) of No. 4 <unk> ; subsequent attempts were less successful . At about 10 : 00 , Chauvel contacted Brigadier General E. S. Girdwood , commanding 156th Infantry Brigade , requesting his brigade temporarily relieve the light horse brigades until they had watered their horses in preparation for a mounted counterattack . Girdwood refused because his brigade was being held in reserve to support an intended attack eastward by infantry in the 52nd ( Lowland ) Division .
