The above account, including the assumption that Mongol sources criticized the crime (still questionable), was described in Jack Weatherford's 2011 book "The Secret History of the Mongol Queens: How the Daughters of Genghis Khan Rescued His Empire". Weatherford calls it "the most horrendous crime of his twelve-year reign and one of the worst Mongol atrocities recorded". A more recent book in Mongol historiography "Women and the Making of the Mongol Empire" (2018) by Anne F. Broadbridge links the "infamous alleged mass rape of Oirat girls" to Ögedei's requisitioning of girls from his uncle Temüge Otchigin's territories without Temüge's approval. Broadbridge notes however that "with all the evidence suppressed, this can only be a surmise". The History of the Yuan or "Yuanshi" (YS 2, 35) and Secret History of the Mongols (SHM 281) speak of a forceful requisitioning of women by Ögedei from the "left wing" and "uncle Otchigin's domain" respectively but do not mention a rape (De Rachewiltz 2004). In the Secret History Ögedei expresses remorse for his act stating "as to my second fault, to listen to the word of a woman without principle, and to have the girls of my uncle Otchigin's domain brought to me was surely a mistake" but De Rachewiltz notes that the entire paragraph listing four good deeds and four mistakes may be a posthumous assessment (De Rachewiltz 2004).
