AND WATER SERVICE The operations of army engineer troops within the army area will be directed by the Chief Engineer. First Army. SUPPLIES An army park is at Souhesmes. and it will be operated by army engineer troops. The following corps dumps are established and will be operated by army engineer troops: Right corps - Dombasle Center corps - Aubreville Left corps - Les Islettes Divisional dumps will be established in advance and operated by divisional engineer troops. under direction of chief engineer. corps. at such places as will be selected by them. Chief engineers. corps. will arrange to establish forward dumps by salvage from captured German dumps and to keep their divisional engineers advised of the location of such dumps. LIGHT RAILWAYS In the American sectors the light railways will be extended and maintained by army engineer troops. Immediately after the advance the light railways lines will be extended to connect with the German system along the following lines: Aubreville---Neuvilly---Varennes (double track) Le Triangle---La Barricade---Cheppy Esnes---Bois de Malancourt---Montfaucon Due to the impossibility of familiarizing new personnel with the light railway system in the time available. arrangements have been made whereby the French personnel now operating this system will continue to function. HIGHWAYS Divisions are responsible for the construction. repair and maintenance of roads in the immediate rear of the line. corps are responsible for construction and maintenance in rear - 106 - of divisions and within their corps sectors in advance of the national route: Les Islettes ---Clermont---Dombasle---Verdun. Army road troops wili repair and maintain highways in rear of the paints above mentioned. As the advance progresses, army troops will take over additional area as the Chief Engineer, Army, may designate, until such time as new limits are defined. Chief engineers, corps, will be responsible for work within above designated limits. Tnere will be held ready in each corps, trucks loaded with road material for repair of roads. Advance dumps for road material are established at the following points: Right corps - Esnes Center COqJS - Foret de Hesse Left corps - N euvilly ELECTRICAL AND MECHANICAL WORK Army electrical and mechanical troops will assist in the installation and operation of water points, and will supply and operate lighting plants for divisional and higher headquarters, and for evacuation hospitals. They will operate a shop at Souilly for repairs to electrical plant. Headquarters of these companies will be established as follows: One company near Clermont One company near Les Islettes CAMOUFlAGE Army camouflage troops are assigned to each divisional sector, and will operate under the direction of division engineers. A detachment has been assigned to the army artillery and will operate under the direction of the Commanding General, Army Artillery. Corps commanders will call on divisional camouflage officers for necessary work for corps artillery. Camouflage dumps are established at convenient points, probably at all engineer corps dumps, though these points have not yet been decided upon. WATER SUPPLY The army water supply troops will supply water to water points, from which organizations will supply themselves. The attention of all organizations is called to the fact that the potable water supply will be exceedingly limited and every possible measure to suppress waste must be applied. Corps engineers will be supplied with information as to water paints available during concentration. Water points in addition to those already existing will be established in rear of the present lines, to which organization transport will go for re-filling. As the advance progresses advanced water paints will be established and supplied by army water transport. Information as to location of these points will be given to chief engineers of corps by the army water supply officer, and to diviSion engineers by the water supply officers operating in their sectors. In general, streams will be utilized by mobile purification units for water points at which sterilized water will be fUrnished. Organization water carts must be accompanied by necessary personnel for operating hand pumps, as this will be necessary in many cases. In addition to the water points above mentioned there are many others in each area. Each town has a water supply, suffiCient for its normal needs, and other paints have been established not in towns or villages. - 107 - All horse watering parties should be in charge of an officer or non-cormnissioned officer who will be responsible for orderly and expeditious watering. Such parties must have sufficient extra personnel for operating hand pumps where necessary. Water pOints are under the control of the Army Water Supply Service. Representatives of this service. including water guards. are empowered to control the use of water pOints. Water guards will wear on the left am1 a brassard with the letters W. S. on white cloth, to be supplied by Water Supply Service. MINING The mining troops available will be used in conjunction with the water supply troops. Responsibility for the destruction of bridges, in case of a reverse, is with corps commanders, and such construction will be effected upon the order of the General commanding the American First Army, or of the officer to whom he may delegate such authority, unless the situation demands immediate action, in which case the corps cormnanders will use their discretion. ENGINEER OPERATION IN FRENCH SECTORS The operations of French Army engineer troops, in First Army area, will be directed by the Chief Engineer, First Army, who will consult with the appropriate French cormnand to effect this result.
