The Japanese Ministry for Foreign Affairs to the American Embassy in Japan
His Excellency the American Ambassador, in an aide-mémoire of September 1st, 1937, conveyed the request of the American Government for the discontinuance of such bombing operations over Nanking of Japanese forces as might result in the destruction of property of non-military character and in the wounding and death of civilians, and also for their abstinence from attacks upon defenceless cities, hospitals, trains, motor-cars, et cetera, with a view to preventing danger to the American citizens who are still scattered in the interior of China.[Page 498]
As His Excellency is aware, Nanking is the pivotal base wherein are planned and originated all Chinese hostile operations against the Japanese forces. In view of the fact that the city is defended by many forts; is possessed of numerous other military organs and establishments in and around it, it is quite proper that against these, the Japanese should carry out bombing operations. It should be stated definitely that the objectives of their bombing are limited, from the standpoint of humanity, strictly to those military organs and establishments, and absolutely in no instance non-military property and civilians are ever made the direct objectives of attacks. That, in spite of all such caution exercised on our part, non-combatants should sometimes be made victims of the hostilities and suffer unforeseen disasters in respect of their lives and property, is also regretted deeply by the Japanese Government. That, however, has been an inevitable concomitant of hostile operations in all ages. In order to ensure, as far as possible, the safety of non-combatants in the present case, it is believed that, in parallel to the caution exercised by the Japanese as above stated, the Chinese on their part should take appropriate measures, such as the evacuation of non-combatants from the neighborhood of their military organs and establishments.
The Japanese Government, as has repeatedly been made known, are most solicitous of the security of the lives and property of the nationals of third countries, including American citizens, in China, and are prepared to do whatever lies in their power to facilitate their withdrawal to places of safety and to afford protection to their property. And they wish to assure Your Exellency that nothing is farther from the thought of the Japanese forces than to make attacks, such as are referred to in the American aide-mémoire, upon defenceless cities, hospitals, trains, and motor-cars, which are not used by the Chinese for military purposes.
