that is, until July 1944. From experience I know that if the commander does not issue any
instructions concerning this or that report addressed to him, this means he agrees with the
measures advanced in the document.

Such was also the case in this instance. Umezu regarded this method of employing
bacteriological weapons in a war against the U.S.S.R. to be the most effective.

In July 1944, when General Yamada Otozoo took up the post of Commander-in-Chief of
the Kwantung Army, his predecessor Umezu acquainted him with this document and with the
activity of Ishii's detachment, and when this report came to me for custody, Yamada Otozoo
did not give any instructions either, which meant that he also agreed with the measures
advanced in the report concerning the employment of bacteriological weapons by dropping,
from aircraft, special porcelain bombs charged with germs.

Since at that time Detachment 731 was not able to supply the Kwantung Army with
sufficient bacteriological weapons, with Yamada's advent to the post' of Commander of the
Army, Detachment 731 was expanded considerably in the light of instructions from the
Japanese War Ministry to increase the output ^>f bacteriological weapons; the detachment
received new laboratory equipment, and consequently, the manufacture of bacteriological
weapons was increased. It is not accidental that in August 1944, soon after his arrival in
Manchuria, Yamada visited and inspected Detachment 731.

Question: When were the instructions received from the War Ministry to increase the
output of bacteriological weapons?

Answer: The instructions from the War Ministry to increase the output of bacteriological
weapons were received by the Kwantung Army Headquarters, in the month of May, 1944,
that is, before Yamada's arrival, and it seems to me, although I cannot affirm this, that the
Ministry's instructions had in mind the ensuring of bacteriological weapons not only for the
Kwantung Army but also for the army in the Pacific. Question: Who of the leading personnel
of the Kwantung Army Headquarters visited Detachment 731, and for what purpose?

Answer: Commander of the Kwantung Army Yamada and staff officer Lieutenant Colonel
Miyata visited Detachment 731; concerning the purpose of their visits I have testified above. .
. .

Question: Did the Commander's order which was issued on August 9 or 10, 1945, speak
only about the destruction of Detachment 731, or did it include other matters relating to this
detachment?

Answer: In addition to the destruction of Detachment 731 and Detachment 100 by blasting,
the order of the Commander of the Kwantung Army, General Yamada, of August 9 or 10,
1945, also provided for the evacuation of the personnel and valuable equipment of both
detachments to South Korea. In line with the same order the topographical detachment of the
Kwantung Army was evacuated deep into the rear.

Question: Why was the valuable equipment of detachments 731 and 100 shipped precisely
