on the wells, the water wells and pumping equipment at Jifjafa. They captured an Austrian engineer officer and 33 men, four of whom were wounded, and killed six Ottoman soldiers. On 9 June 1916 units from No. 2 Section of the Canal Defences formed the Mukhsheib column, consisting of part of the 3rd Light Horse Brigade, 900 camels, non-fighting units and camel transport escorted by one squadron of 9th Light Horse Regiment and 10 Bikaner Camel Corps. The engineers drained pools and cisterns of five million gallons of water in the Wadi Mukhsheib, sealed the cisterns to prevent them refilling during next season's rains and returned on 14 June. At the same time a detachment of Middlesex Yeomanry advanced to Moiya Harab.

Until the railway and water pipeline to Pelusium Station and Romani were built, all water, food (mainly bully beef and biscuits, as packing and transport methods did not allow fresh meat and vegetables), shelters, other equipment and ammunition had to be carried to this position by the Egyptian Camel Transport Corps. With flies attracted to horse litter, etc., provision of safe sanitation was a constant battle. Incinerators were
