They had now challenged the king’s authority, and troops joined the mob outside, where they were pelted with stones from the castle walls by the besieged Jews.
Friday 16 March coincided with Shabbat Hagadol, the ‘Great Sabbath’ before the Jewish festival of Pesach or Passover. According to several accounts, the Jews realised that they could not hold out against their attackers, and rather than waiting to be killed or forcibly baptised, decided to meet death together. The father of each family killed his wife and children, before taking his own life.
Just before their deaths, they also set fire to the possessions they had brought with them; this fire consumed the timber tower. It is not clear how many Jews were present – estimates range from 20 to 40 families, and a later account in Hebrew suggests about 150 people.
