First Hand History of Medieval Greek Fire
The Memoirs of the Lord of Joinville provides a fascinating description of Medieval Greek Fire. Born in 1225, John, Lord of Joinville, Seneschal of Champagne was only twenty-three when he joined the French King Louis in the disastrous Seventh Crusade when Medieval Greek Fire was used by the Saracens.
"... the tail of fire that trailed behind it was as big as a great spear; and it made such a noise as it came, that it sounded like the thunder of heaven. It looked like a dragon flying through the air. Such a bright light did it cast, that one could see all over the camp as though it were day, by reason of the great mass of fire, and the brilliance of the light that it shed.”
His companion, Lord Walter of Cureil wrote:
"Sirs, we are in the greatest peril that we have ever yet been in. For, if they set fire to our turrets and shelters, we are lost and burnt; and if, again, we desert our defences which have been entrusted to us, we are disgraced; so none can deliver us from this peril save God alone. My opinion and advice therefor is: that every time they hurl the fire at us, we go down on our elbows and knees, and beseech Our Lord to save us from this danger."
Medieval Greek Fire fighters stated:
"We put out the fire, and before we had got it under, we were covered from head to foot with the fire-darts that the Saracens shot across the river."
The devastation caused by the use of Medieval Greek Fire is well illustrated in the above fascinating descriptions and first hand history of Medieval Greek Fire by John, Lord of Joinville.
