Its
August
7,
1942,
in
the
middle
of
World
War
Ⅱ.
A
huge
battle(战斗)
is
going
on
on
Guadalcanal
Island
in
the
Pacific
Ocean.
Hidden
in
the
wet
forest,
two
Japanese
soldiers
watch
American
soldiers
roling
out
wire(电线)
from
one
battle
patrol(巡逻队)
to
the
next.
The
wire
wil
carry
telephone
signals,
alowing
different
units
to
talk
to
each
other
and
to
the
base
command(指挥部).
In
the
distance,
gunfire
sounds
and
bombs
explode(爆炸).
When
the
Americans
are
gone,
the
Japanese
soldiers
come
out
quietly
and
put
headphones
onto
the
newly
laid
line
to
hear
something.
Both
speak
English.
They
hope
to
know
what
the
Americans
are
planning
again.
The
first
Japanese
soldier
listens.
A
look
of
surprise
crosses
his
face.
He
hears
a
sing-song
mumble
and
some
strange
gurgles
and
clicks.
The
second
soldier
also
listens.
Its
like
nothing
theyve
ever
heard
before.
Do
the
Americans
have
some
new
kind
of
voice
code?
After
listening
for
a
while,
they
give
up
and
return
to
their
army.
What
were
they
hearing?
They
were
hearing
that
two
soldiers
from
the
Navajo
nation
were
talking
in
their
native
language.
These
special
soldiers
had
the
job
of
sending
secret
messages
over
the
radio
and
the
telephone
by
translating
them
into
Navajo,
then
back
into
English
at
the
other
end.
They
were
known
as
the
code
talkers.
Native
American
code
talkers
let
the
American
forces
share
orders
and
information
quickly
and
secretly
in
the
heat
of
battle.
With
a
code
talker,
there
was
no
need
