"The fall of Byzantium was one of the great events in history, there is no doubt to that. But what is remarkable is not that Byzantium fell, but that it had lasted so long. Though beseiged many a-times, it still managed to survive. Some attribute this completely to Byzantium's famous Greek Fire. First off, how did the Byzantines gain access to this deadly substance, or even gained the knowledge to use it?"

The secret weapon was invented by Calinicus prior to the Arab invasions.
The Military Board is a suitable place to discuss such matters.

Roderick, that input is great and funny to, so many relics of the 'True Cross' to make the Spanish Armada!
