After his divisional headquarters moved north, during his take over of the mounted screen, Hodgson discovered that he had lost contact with the 5th Mounted Brigade. It was nearly dark when, at 17:30, a gap occurred in the line between the 6th Mounted Brigade and Imperial Camel Brigade at Kh er Reseim. Fortunately, hostile soldiers did not attempt to investigate the area before Chauvel sent back his last divisional reserve, the 10th Light Horse Regiment (3rd Light Horse Brigade), to fill the gap. In the growing darkness the light horse regiment succeeded in reaching its position.
