In Gittin 56a-b, we read how the sages warned the Zealots (a.k.a. the Biryonim) to not wage war with the Romans who were holding Jerusalem under seige, but that the Biryonim set fire to the store houses, making war inevitable. Thereafter, Yochanan ben Zakkai faked his death and negotiated with Vespasian, the Roman General and future Caesar, to spare the city of Yavneh and to spare the line of Nesiim -- the family of Rabban Gamliel. Were the sages united in opposing the Biryonim's tactics? Or were there some well-known rabbanim who were known to have fought and died with the destruction of Jerusalem?
