• While the ground to the north, south and west of the position dropped to the river where the Reit Valley opened towards Zeerust away, the ground to the east of the farm rose towards a high point which came to be known as Cossack Post Hill and which was used by the garrison defending the post to send messages to Rustenburg  away  using a heliograph.
• The Imperial Camel Corps Brigade was stopped north-west of Umm esh Shert when confronted by strong opposition west of the river which may have included the Cossack posts dislodged by the light horse advance which had fallen back to Mafid Jozele north of Umm esh Shert and the garrison from Red Hill ( about half way between Umm esh Shert and Mafid Jozele ) which had been forced off by the 1st Light Horse Regiment ( 1st Light Horse Brigade ).
