During this fighting, the 3rd Light Horse Brigade had been sent to reinforce the Anzac Mounted Division, while the 5th Mounted Brigade remained in corps reserve armed with swords. With all brigades of both mounted divisions already committed to the battle, the only brigade available was the 4th Light Horse Brigade, which was ordered to capture Beersheba. These swordless mounted infantrymen galloped over the plain, riding towards the town and a redoubt supported by entrenchments on a mound of Tel es Saba south-east of Beersheba. The 4th Light Horse Regiment on the right jumped trenches before turning to make a dismounted attack on the Ottoman infantry in the trenches, gun pits, and redoubts. Most of the 12th Light Horse Regiment on the left rode on across the face of the main redoubt to find a gap in the Ottoman defenses, crossing the railway line into Beersheba to complete the first step of an offensive which culminated in the EEF's capturing Jerusalem six weeks later.
