GAW-
It has been a long time since I’ve read that period of history, but the first thing that comes to mind is Kol Chotzev, the biography of R’ Sholom Schwadron. In that book his description of the situation betwen the zionists and the Yemenites is documented, as well as his efforts on the Yemenites’ behalf. I am sure I have read about it in other similar works.
Not that I’m trying to help, but be fair. Ignorance of the facts does not change the facts.
