THE ROMAN SIEGE OF JERUSALEM during the first Jewish revolt against Rome (66-70 CE) is the subject of an article by J.E. Lendon reprinted on the HistoryNet website:

Roman Siege of Jerusalem
The prosecution of one of the greatest sieges in ancient history offers a chance to assess the nature of Rome's military discipline and its importance to the success of the imperial army.

I don't have time to read it all, but it looks interesting. Here's more on the piece and the author:
