- 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.
