INTROOOCTION

During

peacetime the United

States

Army

has for

a long

time applied the science of geology

engineering

and con

struction

problems.

Geologists

are

emp oyed

both

in

the Office

of

the

Chief of

Engineers in Washington

D c. , and in the

Engi

neer Distr icts

throughout

the country and overseas. They provide

the

necessary

geologic

services with respect

to the

multi

-

million

dol la r

civi l

and

military construct

·

ion

programs carried

out by

the Army

each

year. The .

design of major construction

projects i s

not

star ted

without

this

geologic

service

.

On

the

other hand i t took two World Wars t .o realize

the

ful l value of applying ·

the

science of geology to military prob

lems

in the Theater of

Operations. In order

for an

army to be

victorious t must control the land; and, in order to control

the

land

i t must take

advantage of a l

l available information

concern

ing

the land . Geology provides military planners with information

concerning the properties

of the ground over which

the army must ·

move

,

shoot

and communicate.

The purpose of this paper

is

to discuss various direct

applications of

geol ogy to the solution

of

military

problems.

Greatest

emphasis

is

pl aced on

the

use of geology during World

War II for i t was in ·this

war

that t'he science .of geology gained

a

permanent

place as

a

useful

tool

in

military

operations

. A

brief history of military geology

is

included as background to

portray the evol ution . of military ~ o l o y to the

present

state

of- the -art .

HISTORY OF MILITARY GEOLOGY

BEFORE WORLD W R

. Before Worid

War I

In

the

years preceding

World

War

I

there

are

scant

t

references

to the value

of applying geology

to m il i tary

problems.

This

was

because geology

was

s t i l l

a

relatively new science

and

was neither

fu

l

ly appreciated nor being extensively applied by

the engineering sciences.

Major

General J.

E.

Portluck of the

British

Royal Engineers ,

appears

to be

the

f i r s t professional

soldier to recognize

that a knowledge

of

geoiogy

wou

l d

be an

aid

1

in

war. General

Portluck

p ~ l i s h e d

a

rudimentary

t reat ise on

geology

in 1868, discussing

the

various

~ p p l i c t i o n s

of the

science

to military problems.

Major A.

Marga, a French

engineer

off icer ,

published

a

t reat ise in

1885

in which

he

recognized

the

influence

of ·

geology

in the matter of controlling troop

movements

by i t s determination

of

the physical

character of

.

soil . He recognized

that:

The

character

of

the

soil ,

which

is known

by

the geology,

greatly in

-

f l

uei_l.ces

the passability of a

region

and the.refore indicates

the

difficul t ies

which

armies

must overcome

in their marches.

between

1897 -19 8

at the school

of

at Fontainbleau.3

a r r ~

placed

a great

deal

of emphasis on geology

in

his physiographic

treatment

of

to

pography.

His

principal work

predicted with

a

remarkable

degree

of accuracy the

control exercised

by physiography

on

the military

operations of

World

War I .

During the decades prior to

World

War

I

the

French

clearly

established themselves as the leaders in the

fields

of military

topography, the relationships

between

topography

and

geology,

and

the

influence

of

topography

on

strategy

and

tact ics -

particular ly

in Central Europe.

Although

geology received l i t t l e recognition in military

textbooks

i t was

by

no means ignored in

the

t ra ining

of

officers.

Geology was

s t i

l l an embryonic

science

when i t was

introduced

into

the

curriculum at the

United

States

Milita

r y Academy in

1823,

the

Academy

being

one

of the

f i

rs t educationa

l

ins t i t

ut ions

in this

country to introduce

a formal

course of instruction in geology.

This

was

apparently given for the purpose of general culture,

with

.

l i t t l e or

no

re9ognition

of

i t s application

to war. Both

British

and

French officers received instruction in geology

Lt Colonel Charles Cooper King

gave

a

course

in military geology

to

Brit ish officers

a t the

Camberly

Staff College.4 Another

course

was

offered at

the Chatham

Engineer School

.

Both of these

courses

were abandoned many

years

befors

Wor

l d

War

I .

Colonel

King

seems

to

be tpe

f i r s t professional soldier to recognize the

wide application

of

geology

in

military

problems

- except

in the

f i

eld of

military topography .

Lit t le

attention was

paid,

however,

.

to his

pioneer

work in the field .

The

f i r s t practical

use of

geology in direct connection with

military operations dates

from. the Russo-

Japanese Wa

r (1904-

1905 ,

in which

the Russian

Army

used a number of

geologists primari

l y

as

advisers

in

constructing

for t if ications.5 Duri ng this same

war

Japan made a geologic survey of Korea and i t

is believed

l ikely

that

some of

the

results

may

have been

~ u to

immediate use . 6

Another earl y application of geology to military

problems

was made by

the

French military geographers or

mi

l i tary topog

raphers.7

The

definite systematic

relationship

between the to

pography and

geologic

s t r u c t u r ~

of

France coupled

with

numerous

wars

throughout the

centuries,

provided the French military

stu

dents with many

examples

of the control of military

movement

by

the h i g h l n d s ~

scarps,

and water courses of

France.

These ex

amples

represented

a

trend toward

presently

used in

planning

wars of

movement.

But

th is trend was

abruptly

al tered

by the

posit ion

or trench warfare of

World

ar

I .

Shortly before the outbreak of

World

ar I

Captain al

ther

Kranz of

t he Corps

of

Fort if icat ion Engineers

of the

German Army, .

call ed attention to the

use

of geology in war. Captain Kranz who

was himself a trained geol ogist br ief ly sketched

several

f ie lds

of usefulness of military geology in an art icle which

he

published

in Berlin

in

1913.B

Kranz advocated

that

military geology

be rec -

ognized

as

a

special profession and that

selected

officers

be

s p e c i l ~ y

trained

as

professional military

geology

officers.

Kranz ' s recommendations at t ract.ed  l i t t l e attention until af ter

the

o u t b ~ e k

of World

ar

I. Then

such

c9ntrov

ers

i

es

arose as to

the

best

military

use

of geology that

public

discussion i n technical

journals and

the press

was stopped by

mi

l i ta r y censorship in 1916.

During

World ar I.

Although

geol ogy was

d e f i n i t ~ l y

recognized by the

principal

contending

armies during

World

ar I

i t s

ful l usefulness

was

by

\

no means realized.9 Relatively few officers in

the

hi gh

command

of the

armies t

hat

employed

geologists

appreciated their valu

able

services. Consequently they failed

to

seek

·

the

advice of the

geologist on problems

that

clearly lay within his f ield. Geology

was regarded by m ny as a

speculative

and abstract, rather than as

a

practical

and concrete science.10 

In

the early

part

of the war

there

are

numerous examples of projects o r . o p e r ~ t i o n s involving

great

loss

of

time

.,

energy,

and l i fe whi ch could have been

avoided

by the application of a basic knowledge

of

geology.

During

the great Batt le

of Verdun,

an order was given

for

a

body of troops to

dig in

on the high plateau of the

Cotes

de

Meuse which ended

in disaster

and

needless

loss of l i fe . A casual

glance at the available geologic m p would have shown that the

plateau

was

underlain

by hard limestone

with

less

than

a

foot

of

soil cover. The

material

could

not be

excavated

with the l ight

tools furnished or

even

with

proper

equipment

in

the time

available. l l

Front l ine

dugouts and trenches, located without any con-

sideration

of the ground water conditions, were rendered useless

by

f i l l ing with

water. Numerous tunnels for attack

galleries

were

star ted

only to be abandoned after a great expenditure of time

and

labor when crossed by hard igneous rocks or hard

sandstone.

Road

metal

was transported from England

to

France in

ignorance

of the

fact that a geologist was

able

to designate

readily

accessible

sources in the Theater of Operations. The witch-hazel stick was

being used

to

locate

sources of

ground

water and hundreds of

wells

were driven that provided no water. Hospitals and a i r f i e l d ~ were

water.

·

Many other

similar

mistakes could be

cited

that clear ly

emphasized the

need for basic

geologic i n t e l l i g ~ n c e on

or

near

the

front.

As the war progressed and stabil ized into s t t ic

trench

war -

fare greater

use was

made

of the

geologic information available

.

The

geologic staffs

of the

various

armies were

increased;

and in

certain

of

the a ~ i e s particular operations

were

not undertaken

without f i r s t

since

\

the

the

The principal contributions of the

during the war were the provision

si t ing of field

fortifications,

and

locating sources

of construction

principally road metal. Although

the

employment of

developed

usefulness, i t s

contributions were

widely recognized.

After the war the Chiefs of Engineers of both the

In

Germany i t was believed that

the lack

of

understanding of

geology

in m ili tary circles , and the lack of

understanding

of

military problems in

geologic circles,

had

limited the

use

of

g e o l ~ g y

in World War

I

I t was proposea that for the future there

should be a specially trained body of professional military geolo-

gists

who

would have

broad responsibilities

in many phases of

military operations . Plans for a comprehensive training program

were

developed

to make military

geology

a part or the regular

university training of a l l geology students. Those

students

specializtng in military geology

would receive military

training

in

the

Cotps of Engineers after which they would

be

commissioned.

Training in geology was also

to

be

included

in.

the

curricula of

a l l military c ~ d e m i e s and officer training schools . I t is be-

l ieved that this

plan

was implemented, a t least in part, prior

to

the

mobilization

of

the

new German rmy that entered World

War

I I

27

Between 1932 and 1939 many papers on

military

geology were \

written by

German scholars ,

but despite this

interest the govern -

ing

concept of

military

geology continued to be that of

sta t ic

warfare conceived

during

World War I .

2

prevailed

among military geologists until as la te

as

1941. Even

though

the

military

thinking

lacked

continued interest in

the

subject led

to the re -

establishment

, in

1935,

of

the

11

Wehrgeologie

11

or

German

Arm.y geologic organization.29 

In

the

USSR, geologywas made a part of the regular education

of army

officers

. Functions of

military

geology were performed by

geologists organized into

11

hy

drotechnical

divisions,

operating

under

the

Army General

Staff

. These div

isions were

given respon

sibi l i ty

f?r

l l matters

pertaining to

water supply and sanitation,

and construction of maps showing geology, h y d r ~ l o g y

road

and

transport routes,

deposits of road metal and ball ast , and

the re

sults of seismic surveys . 3° 

The application of geology to the military

arts

and science

did

not fare too well in the United

States during this period.

This should not be too disconcerting, however, for t

only

ref lects

the general att i tude

that

prevailed toward the mili tary profes

sion. Who could think about geology when

the

Army was conducting

maneuvers

as

la te

as

1939

with

wooden

r i f les

and mock

tanks? We

were extremely fortunate

in

another sense,

however,

for great

str ides were made in

the

practical applications of geology

to

l l

other branches of engineering, and geology came to be

widely recog-

nized

as

a

concrete

and practical science . 3

I t should

be

speculated that

mi.

l i tary geology was considered

by

other

countries and in particular by Japan . For a long time

the Japanese were open- handed

with

geologic data on their

home

land

; but

in

1937,

they

stopped exchangirlg

this data with other

countries . Japan's

pride in i t s botanical

accomplishments, how

ever,

tended

to defeat th is censorship in geology. They invited

botanists from many countries to vis i t their islands to observe

the ir

botanical feats.

The

botanical information

thus

obtained

proved

important in geologic

warfare;

for

plants

can

be a

guide

Despite

the recommendations

of

the Chief

of Engineers based

on

our

World War I

experience

concerning the i ~ p o r t n c e of geology

entered

World War

I I

with

no

for

including military geologists as an organic

part

of an:y troop unit

or

The awareness

among

the

the

use of

geology and

the geologist was

almost nonexistent. Shortly

after the

United

entered

the war

i t

became

apparent to

the Chief

U.

that

the

Army

was

not

equipped

to

fUrnish

the

geologic information necessary concerning prospective areas

of

had developed into a war of

movement in contrast to the position warfare of World

for

and military

construction projects within the United

i t s organization

could

not

tackle the gigantic problem

of providing

for the

There was

not sufficient

time

available

for

the

Corps of Engineers to

build

a geologic

reference l ibrary of

the

requisite

size

to

conduct the

needed geologic investigations. The means by which this problem

was solve.d

exhibits

an

outstanding

example of cooperation between

as an important scientif ic

in

the

as

to

in the solution

of

a large variety of practical problems . Yne

civil ian

make

the

Military Geology

Unit

does not appear

to have been a great handicap to

the

successful completion of

i t s mission . H ~ w e v e r a basic

understanding of military

sci

ence and

military

engineering problems by the members of i t s

s taff would have

faci l i tated the

work of

the unit.

From our

wartime

experience evolved, however, a fundamental

requirement

for geologically trained

officers

in the Corps of Engineers

to

give military direction to

our

civil ian

military geology

organization.

Also

i t

was made

apparent

that

a

regular

Engineer Table of Organization

and Equipment Unit which

would

include

a military geologist should

be

organized within

the

Army structure to serve in the Theater of Operations to

provide

geologic

services .

The Challenge.

The

application of geology to

problems

was

not

forgotten after World War I I as i t was during the period fol

lowing World War I There have been major organizational

changes

in our military structure

but the

basic

mi

functions

have remained

- including

the

function of

provid

our

is

that in

the

the most important

services rendered by geologists was locating sources

of potable

water

for

our troops

in the

f ield

. Furnishing an

adequate

water supply is

always a major

responsibility of

the

Engineers

and

in

most

regions

the

water

supply provided for

civi l ian

consumption i s not sufficient for military needs . When

wa

t

er

cannot be obtained from

surface

sources  

i t

is a primary

duty

.

·

of

the geologist

to

locate

sources

of

ground

water

from sub-

surface water bearing

s t rata

that

can

be obtained t feasible

depths from new wells and bore

holes

.

Our

military forces

presently deployed overseas have

won

much

favorable comment in

helping certain

emerging

nations

develop sources of

potable

water •

In

areas l ike

the Greenland ice .cap unique methods

have

been devised to

pro

vi

de

water

.

One of the

most

productive

methods is to dri l l many feet into the ice cap and use steam

to

melt

the

ice . The resultant water is then pumped to the

surface

for

subsequent use

. The

water obtained

is

reported to

be as

pure

as dist i l led water purchased from

the

corner drug

store .

General construction. Construction problems which

can

best be handled by military geologists

include

1. The selection

of favorable

sites for

airf ields

.

2 . The

selection

of favorable routes

of

The location

of

sheltered harbors and morrings •

4.

The inspection

of

mines and the

 

selection of other

favorable

for

hangers, munition dumps) storage, etc .

5.

The selection

of

favorable si tes for fort if icat ions ,

gun emplacements, and other heavy structures .

6. The

location and

rehabilitation

of

existing .

quarries,

and

the

location

and

development

of

accessible

new

deposits

of

building stone, gravel,

road

metal, and sand for

use in

general

construction work .

7. The study

of

drainage problems with a view to the con-

struction

of

dams, levees, and canals for the purpose

of

either

drainage

or

flooding to create obstacles.

8pecial

problems

.

Military

geologists

are

frequently

called in

as

consultants on a

variety of

engineering and scien-

t i f i c

problems

which affect

military operations.

ome of

these

special

problems include

the

following

:

1. Reports on the

dist r ibut ion

and

effect of magnetic

ironbearing

rocks on compasses and other direction finding

stations, radio propagation, mine d e ~ e c t i n g etc .

2. Selection

of key

mineral and fuel oi l production cen-

te rs in

enemy

te r r i tory

which

are vulnerable

to bombing.

3. Evaluation of mineral and oi l deposits

in

occupied

te r r i tory which may be

of

use to occupying forces.

i s

continuing to

provide

those

addition,

the recommendation

that

the

has resulted in

the organization

of

such a unit .

Mi

prepared by the unit

during

the war were hampered

by

shortcomings

in

geologic and so.i l s

data in

foreign

areas

especially some of

the

areas in

the

Pacific

.

Immediately

after the war the

overseas

teams

in occupied areas

conducted field   sur.veys

to evaluate the

accuracy

of

the

studies

prepared by the

unit.

n

example of thiS type of work was the Report

of Recon-

naissance of Coronet Operation

Area,

1-2

March

1946.54

One

year

after

Operation Coronet,

11

the code

name

for

the

invasion

of

Japan, was to have taken

place,

a reconnaissance

of

the

proposed

landing

beaches

was made.

~ n s

reconnaissance

was

to

compare

the intell igence

upon

which

plans

for

the

landings

were

based with actual conditions vThich would

have

confron:ted

tb e

invasion

forces . t was found that the sand on one of the

beaches contained sufficient magnetite to destroy the

effec

tiveness of magnetic mine detectors . This characteristic had

not been mentioned

in

the

study

. I t was

further

found

that

on

another

of

the beaches the

gra

in size

and

moisture content

of

the sand would have made vehicular t raff ic from the water 's

·edg

difficul t or

impossible.

I n September 1948, as the result

of

a reorganization

within the

U

S. Geological Survey,_ the Military Geology Uni t

was

upgraded

to

section

status

and

a few months l a te r V as

ele

vated to branch level . The

official

name is now the Military

As

previous

l y

mentioned

the

Un

was one

of our f i r s t

educational

ins t i

t

utions to provide

a

c

ourse

i n geology; but

that

course

wh

i ch was

discontinued in

1917,

was primarily

cultural

. From

then unt i l about 196 there

was very l i t t l e mention

of

geology

in

the

curr

i cu l um t the

Academy

except

for guest

lecturer

presentations . In 196 there

was a broad

curriculum re

- ev al

uation

t

the

Academy which re

sulted in

new

subjects such as

physical

geography world

geog

raphy

,

astronomy

and

astronautics being

added

to the curriculum

.

The Academy

now

has

a 30

hour course

in

physical

geogr

aphy

which

includes geology and related earth sciences . The applications

of these sciences to military probl ems is stressed.

Many Corps

of

Engineers officers pursue graduate

studies

t civi

l

ian col

l

eges

and un i vers i t ies

for the purpose

of

ob

taining advanced degrees

. Geology is among

the subjects studied

t s9me

of

these insti tutions

which

further increases the Army   s

base of

geologic

know

l edge. Many more

office

r s have become

aware

of

how

the applicatio

n of geology

can

be a

valuable aid

in solving certain

of

our

mil

problems.

CONCIDSION

Geology

has

in

solvi ng numerous

pr

of

was made apparent i n

the

relearn the

lesson

during

World

War I I

The

reliance

on a

civil ian organization to provide the Army with the greatest

portion

of

the geologic information required has

not

been

any

great h

inderance in the provision

of

th is servi

 ce but empha

sizes the feas ib i l i ty

of

cooperation between the various

governmental

agencies.

I t is

expected

that

th is type of

_

·cooperation wil l further increase with the

application

of

nu

cle

ar

power and weapons and

our

advancements

into space.

The requirement for the

Army

to have

organic uni ts

capable of

providing geologic

services

in

th

e

f ield

is

also

appare

nt

and

such units have been

organized

and are presently operating

in

the

f ield .

The

Army has also emphasized the

·

need for geologic t rain

-

in

g

of

i t s personnel

not

only in i t s own

mi l

i tary schools but

in

civil ian

ins t i tut ions as well.

A

course in Military

Geology,

offered as

a

part

of

the regular undergraduate instruction

open

to a l l

geo

logy

students

in our leading

universi t ies

would

further extend the

awa

reness in th is

important

f ield . A

greater

understanding on the part

of

geologists and military

men

alike will

go

fa

r

in

improving

future

applications of

g

eolo

gy to the

military

science . Only the

his to

ry

of

the

future

can re la te

the as yet unforeseen

applications

of

geol

ogy to the military

science.
