Oh, ok, I actually had no problem with your Messada comment, it was all of that singing... lol

anyway, I don't remeber the exact year it happened, it happened between 70-80 A.D., it was I believe after the Temple in Jerusalem had already been destroyed, Messada was the last stance against the Romans, and when they saw the Romans starting to climb up, they understood they had no chance, and commited mass suicide.
