Looking for a quote from Johannes Bronkhorst

I recall, years ago, reading about Buddhist treatises on rebirth, composed some long time after the Buddhas death. It was a very brief reference of Johannes Bronkhorst's, probably in a footnote. I've searched various of his big works looking for it, and numerous papers. If anyone happens across a likely candidate, would you please let me know? It seemed to indicate there was a period in which one faction was trying to convince another that the Buddha taught rebirth. I'm interested in learning anything I can about how far back the debate that lives on today goes. Thanks for any and all help.
