Thanks for reminding me that we're not in ask historians, and thus have a bit more leeway in our cites:

>Sieges against Antioch had a history of costly failure. It was well known that the complicated instructions and long deployment time of their weaponry made Antioch's military an ineffective field force. At home, however, these disadvantages were irrelevant; with time for a careful, deliberate deployment, their "holy" hand grenades proved decisive against invaders, human and animal alike.
