Crimes against humanity. Frank S. TavennerMr. Roy Morgan19 June 1946 Chief, Investigative Division 1.Following our conversation with Mr. Williams of several days ago, I am giving you a short memorandum as requested regarding the use of thousands of coolies in the construction of fortifications along the Manchukian-Siberian border and a harbor near Teintsin. 2.Mr. Idu of the Chinese Section will be able to furnish the approximate date of the transportation of coolie labor in sealed box cars to Manchuria and may be able to furnish eh names of witnesses to this fact. I understand that no satisfactory proof can be presented that these thousands of coolies did not return. It is stated that the bodies of the dead coolies were seen floating in the river below the place where the fortifications were being constructed, but I doubt that any reliable evidence to this fact can be developed. 3.The situation is virtually the same with regard to the use of coolie labor in the construction of a harbor near Teintsin. 4.It is not known whether the Russian Section has any information regarding the former incident. We discussed the possibility of developing the case from the inside by locating and interviewing members of the Japanese units who were serving in the particular areas at the time the events occurred.
