Companies of the Egyptian Labour Corps were supplied to work on construction of railways and roads. They worked to manage sanitation, were employed as stevedores and on wharf construction. They loaded and unloaded lighters, carried stores for supply depots and loaded lorries for the
ASC. They laid the pipelines, built the railway
embankments and helped lay the track, loaded and unloaded the trains, manned the
surf boats, stowed or discharged the cargoes of surf boats from supply and store ships, and were employed everywhere on conservancy duties. The corps constructed the duplication of the
Zagazig to
Ismailia section of the railway from
Cairo to the
Suez Canal, built
metalled roads out into the
Sinai desert and laid water pipelines. About of railway, road and pipelines were laid in a few weeks for the forward defence of the Suez Canal before it was extended eastwards into the Sinai. They also assisted in horse and camel hospitals, and travelled to
Akaba to assist
Lawrence in his work for the
Arab Revolt. Beside the pipelines and the railway, hundreds of miles of
wire netting roads were laid across the sand and pegged down, and great reservoirs, to hold huge quantities of water supplied by filters at a rate of a day, were constructed. At the beginning of December 1916, the
Egyptian Expeditionary Force had a strength of 150,000 British, Australian and New Zealand and 6,000 Indian troops, and 13,000 Egyptian labourers. Rail was laid at the rate of a month and the pipeline construction eventually caught up with the railway at
El Arish in February 1917. At this time General
Harry Chauvel ordered aerial counter-attacks on German and Ottoman positions to stop as retaliation against German aerial attacks on the Egyptian Labour Corps, which stopped the railway gangs from continuing the strategically vital railway on to
Rafah. Under the supervision of administrative officers of corps, divisions and sanitary sections, troops worked alongside the Egyptian Labour Corps in the fight against pests in the
Jordan Valley. This involved, among other strategies, draining swamps, and constructing hard horse standings. Near
Jericho in 1918 a 600-strong company of the Egyptian Labour Corps worked for two months to suppress mosquitoes breeding in the overflow from the
Ain es Sultan spring. ==Recruitment==
