Developments at Mersa Matruh in 1941

In September 1941, Mersa Matruh was occupied by considerable force. The 1st South African Division manned the perimeter and were supported by a machine-gun battalion. The machine gunners happened to be Australians. They had some artillery: "three field artillery regiments and two anti-tank batteries". The artillery commander was from the 9th Australian Division, a brigadier. In the usual ironic situation, the 9th Australian Division was sent to Cyrenaica to train, as the conventional wisdom at that date was that this was a back-water location where nothing much could be expected to happen. The conventional wisdom did not acknowledge the presence of General Rommel, who upended everyone's calculations, even the Germans and Italians. Tje 9th Australian Division, since they did not expect any action, had left their artillery at their base. While this frustrated the gunners, this saved them from being caught up in the chaos in Cyrenaica when Rommel first attacked, and besides, the gunners were lacking equipment. The 9th Australian Division was forced to depend on British artillery located in Cyrenaica.
The changing situation soon left the Australian gunners providing the second and third lines of defense for Egypt. After that happened, the British were sufficiently motivated to find vehicles and guns to equip the Australians. They were given old guns, such as 18pdrs and 4.5in howitzers. The Australians received their equipment near Alexandria. They got a taste of the desert environment before being sent to Mersa Matruh. Two regiments arrived at Mersa Matruh, but the 2/12th Field Regiment was sent to Tobruk.
Two British field regiments were covering the coastal area. They initially moved up guns in the dark so that they could reach the Halfaya area. They figured out a better plan, which was to to move one gun up on the sand dunes and shoot at whatever movement that they could observe. This usually drew a disproportionate amount of return fire. They reported results as if it were a cricket score. For example: "195 for 10" meant that they had fired ten rounds and caused the enemy to fire 195 rounds. An Australian officer was permitted to command the operation for 23 July 1941. His gun fired 28 rounds at a "working party", vehicles traversing Halfaya Pass, and probably destroyed a staff car.
When the Australian gunners had arrived at Mersa Matruh, they realized that they needed to improve and expand the artillery positions. One important point that they realized was that the defensive perimeter needed to be expanded to enclose the high ground that dominated the site and harbor. They did not want to provide the enemy with access to the position which overlooked the site. This is based on the account in Vol.III of the Australian Official History.
