ZEREBA AT ABU-KLEA

"A stone breastwork was rapidly thrown up in the
fading daylight by the Guards Camel Regiment on the
plateau in front of that on which the camels had been
halted and tied down. It was about fifteen feet higher
than the latter and divided from it by a narrow depression
in which the horses of the Hussars were picketed.

A breastwork of camel saddles and boxes was also
immediately constructed on the right face with wire
entanglements in front. The left face was defended only
by a few straggling mimosa branches over which the
Engineers stretched a single wire to represent an entanglement.
The front breastwork was held by the Heavies, who
lay two deep behind it with the Guards in their rear ; the
right left face by Company G of the Royal Sussex, with
only one man to every four feet of ground allotted to
the detachment. Another company of this regiment
occupied a hill in rear of the zereba during the night.
The right front was defended by the Mounted Infantry.
The three screw guns were placed at the right front
corner."
