I don’t have the book handy but I don’t recall seeing what he gave as a source. I think CougarGA7 has said that he was not very thorough in documenting his work.

It's been ages since I read that book and I no longer have it in my possession. Knowing Toland, my question was more rhetorical than anything else.

Toland wasn't very thorough on his sourcing. It's one of the reasons I don't use "Rising Sun" as an academic source, even though I found it to be a good book personally. Here is the citation for the section of the book in question. Now keep in mind that there is no numbered citation, only notes for the chapter (17 pages long in this case) to cover anything said in that section:

11 "To Show them Mercy Is to Prolong the War"

Jones, Clifford Bluemel, Takeo Imai, Akira Nara, and Carlos Romulo; Colonels Susumu Nishiura, Takushiro Hattori, Kumao Imoto and Nobuhiko Jimbo; Antonio Aquino; Roy Castleberry and numerous survivors of the Bataan Death March; corresponence with Captain John Bulkeley and Mark Wohlfeld; "A Strange Order Received at the Bataan Battle Front," an unpublished article by Lieutenant General Takeo Imai; "Dawn of the Philippines," privately printed pamphlet by Nobuhiko Jimbo; "Bataan Death March," doctoral thesis of Stanley Lawrence Falk; the Homma Diary (unpublished); documents for the defense at General Homma's trial; MORTON: I Saw the Fall of the Philippines, by Carlos Romulo; MacArthur: His Rendezvous with History, by Courtney Whitney; They Were Expendable, by W.L.
