Trench warfare now set in for the summer, while the EEF was reorganised under new command and intensive training was carried out behind the lines. On 20 October 158th Bde moved up to the concentration area for the new offensive (the Third Battle of Gaza), taking over the front line and reconnoitring the ground over which they were to attack. On 25 October the brigade moved into No man's land and established an outpost line.On 27 October the division advanced to take over a line of hills already occupied by the Yeomanry of the 8th Mounted Brigade, the movement being covered by 1/5th RWF. Later the battalion was sent with a field artillery battery to occupy Hill 630 on the left. When the battalion was still away the Yeomanry outpost on the hill was overwhelmed by a Turkish attack. The Turks then had perfect observation over the plain where 1/5th RWF was moving up, followed by the rest of 158th Bde and then 160th Bde, and began shelling the concentration of troops. Once the division was re-organised for an attack, the Turks slipped away and the line of hills was easily reoccupied. The main attack, a turning movement (the Battle of Beersheba), began on 31 October; 53rd (W) Division on the left flank was hardly engaged, though part of 158th Bde in 'Smith's Group' made a demonstration with 1/5th RWF advancing to keep touch with the attacking troops to the right. The battalion engaged the enemy with long-range machine gun fire, and ended the day on outpost duty.
