1, The Gnemy, having occupied the area in.the vicinity of

Yamagata, is awaiting the arriva l, of reserves andw ill pro

bably launch an attack.' The.main enemy pos ition is not

cle ar, but, judging bythe relat ion between tho enemy.streng

th and the terra in of the Yamagata area as well as the sec

tors occupied by both main forces, i t i s l ike ly to be in

the aroa south of Tendo and north of Yamagata, while a

strong element w il l probably occupy the Tendo area,

2, In view of i t s miss ion, the d iv is ion must quickly crush

the enemy in the Yamagata area before he can be reinforced.

Therefore, taking into accouiit the condition of its elements

and the d is tance to i t s objective , the d iv is ion

for the d ivis ion , in order to fac i l i ta t e subsequent opera

t i ons ,

to take as i t s immediate objective a l ine connecting

Kawayoke, Midaragawa-mura, and Michiman, There are three

.roads which can be used for th is operation: the Kawashima

Nagatoro-Hanyu-Narifu road, the Koshu Highway, and the

Tateoka-Higashine-Harazaki road. In tho event of combat it

would be advantageous to secure a foothold onthe h il l to

-the, .east. Therefore, a strong force must be moved on the

last named road; the main strength, of tho division, to keep

its, movement unhampered, must move on the Koshu Highway,

which is a good road5 and a small, element must move along

. the f i rs t named road to protect our r ight
