important innovation in the getting of water, which enabled the mounted units to operate more effectively over wide areas of rocky desert areas and sand dunes on reconnaissance, was the Spear Point, developed by Australian Engineers designed to be attached to a pump: A 2 ½ inch pipe was pointed, perforated and covered with a sheet of fine perforated brass. This was driven down into the water area by means of a small pulley bar and monkey, or by a sledge–hammer; and additional lengths of pipe were added if necessary. The ordinary General Service "Lift and Force Pump" was then attached. This arrangement proved so efficient that "Spear Points" were issued to every Squadron in the Division, and the RE Troops carried a number of them. Our men were thus enabled to get water at any of the hods in the desert in a very short space of time. Once the brackish water was found, a medical officer assessed it as either drinking water, horse water or not fit for horses, and signs were erected. In June, the 1st Light Horse Brigade carried out reconnaissances to Bir Bayud, Sagia and Oghratina, to Bir el Abd, Hod el Ge'eila, Hod um el Dhauanin and Hod el Mushalfat. Another routine reconnaissance by 2nd Light Horse Brigade took place on 9 July to El Salmana. Just ten days later, El Salmana was occupied by Ottoman Army units as they concentrated for the Battle of Romani. In the middle of June the No. 1 Squadron, Australian Flying Corps began active service with "B" Flight at Suez doing reconnaissance work and on 9 July "A" Flight was stationed at Sherika in Upper Egypt with "C" Flight based at Kantara. Battle of Romani The battle of Romani took place near the Egyptian town of that name east of the Suez Canal, from shortly after midnight on 3/4 August until the invading force retired during the late morning and afternoon of 5 August. The Central Powers force of Austrians, Germans and Ottomans, led by Kress von Kressenstein, sought to stop the British Empire reclaiming the Egyptian territory of the Sinai Peninsula and cut the Suez Canal by bringing it within artillery range. It numbered 12,000, mainly from the 3rd Infantry Division, with Bedouin irregulars, German machine-gunners and Austrian artillery from Pasha 1. Romani was defended by the 52nd (Lowland) Division, and the 1st, and 2nd Light Horse
