Yu Chi Chan (Guerrilla Warfare) only enemy. Japan is unable to employ her entire strength in the attack on China; she cannot, at most, spare more than a million men for this purpose, as she must hold any in excess of that number for use against other possible opponents. Because of these important primary considerations, the invading Japanese bandits can hope neither to be victorious in a protracted struggle nor to conquer a vast area. Their strategy must be one of lightning war and speedy decision. If we can hold out for three or more years, it will be most difficult for Japan to bear up under the strain.

In the war, the Japanese brigands must depend upon lines of communication linking the principal cities as routes for the transport of war materials. The most important considerations for her are that her rear be stable and peaceful and that her lines of communication be intact. It is not to her advantage to wage war over a vast area with disrupted lines of communication. She cannot disperse her strength and fight in a number of places, and her greatest fears are thus eruptions in her rear and disruption of her lines of communication. If she can maintain communications, she will be able at will to concentrate powerful forces speedily at strategic points to engage our organized units in decisive battle.
