PRINCIPLES OF WAR

Although, the principle of Sustainability is normally
thought of in the context of an offensive or defensive
action, in the case of OVERLORD, looking at the logistical
and engineering efforts that were undertaken to be able to
ultimately achieve and sustain mass provides an interesting
study. The purpose of sustainability is to concentrate the
effects of combat power at the most advantageous place
and time to achieve decisive results.

Due to limited landing craft (enough built for five divisions),
numerous obstacles along the beach and heavy defences
of the Atlantic Wall, achieving sustainability under fire on
the beaches of Normandy on D-Day would be difficult.
Achieving and sustaining the build-up without adequate
ports or secure airfields in enemy territory would be a
paramount undertaking. To begin with, massive supplies,
personnel, and equipment would have to be pre-positioned
in England in preparation for OVERLORD. These efforts
were complimented by the development of innovative
engineering concepts and supporting specialised
equipment.

Logisticians faced unprecedented challenges during the
build-up in preparation for the cross-channel invasion.
They started production planning two years in advance of
D-Day, the build-up of supplies in England a year ahead and
planning of detailed logistical support six months before
the landings.

Offensive Action

Military forces take offensive action to gain and retain the initiative.
In most circumstances, such action is essential to the achievement of
victory. When offensive action is required, it must be swift, decisive and
should be directed towards the achievement of the end state. Offensive
action is not limited to the application of force but encompasses the
