Greek Fire: The Byzantine Empire's Secret Weapon the Ancient World Feared
The year was AD 678, 46 years after the death of the prophet Mohammed. Now the Mohammedans, determined to bring the light of Islam to Arabia and beyond, were streaking across the whole of the Middle East like a comet. Their statecraft, as it turned out, was as basic and unyielding as their faith. Those who would not answer the call of the muezzin would be treated, instead, to the sword.
For years, the Muslims had successfully managed to nibble at the borders of the Byzantine Empire. In turn, first Lebanon, and then Syria were lost, absorbed forever into the Arab world. By the early 670s they were ready to start westward. Working their way across the Anatolian peninsula in what is now Turkey, the Arab forces were relentless, insatiable, and seemingly unstoppable. With their sights firmly fixed on the West, the Saracens (from the Greek Sarakenoi, a corruption of the Arabic word Sharqiyun, meaning “Easterners”) began gobbling up bits and pieces of territory, as they edged ever closer to the real prize: Constantinople.
Flush with visions of victory, the enormous Saracen fleet hoisted anchor and set sail from Kyzikos. Moving across the water like a seaborne dagger, they hugged the coast and were soon within sight of their goal, heading directly toward the storied walls of Constantinople. With the rays of the eastern Mediterranean sun shining and the glistening towers of the fabled fortress-city beckoning before them like a mirage, it must have seemed to the Saracens as if Allah himself was smiling down upon them, ready to reward their zeal with the heavenly seal of victory. Before the sun would set that day, however, many a Muslim soul must have wished that they had never left the harbor.
Streams of Liquid Fire
Catching sight of the numerically inferior Byzantine navy, which could now be seen gamely sailing out to meet this threat, the men of the mighty Islamic armada must have been convinced that this jihad was going to be a cakewalk. If indeed any of them even noticed the single bronze tubes jutting out from the prows of each of the Byzantine ships, they paid them no mind. They were about to receive the surprise of their lives.
As the Byzantine ships drew closer and closer, looking like nothing so much as sheep coming to the slaughter, the Saracens, far from being concerned, drew themselves up and prepared, no doubt with great relish, to pound the tiny flotilla into splinters. Then, something extraordinary happened, something never before seen in the history of warfare, for it was the Saracens, and not the Byzantines, who went to the slaughter.
Suddenly, from out of the mouths of those innocuous-looking bronze tubes came the dragon’s own breath, pressurized jets of liquid fire that shot across the water in short, volcanic bursts, immolating soldier, sailor, and ship’s timber alike. The flames, which literally engulfed everything they came into contact with, could not be extinguished. Like modern napalm, these flames stuck to everything they touched. The hapless Saracens ran about the flaming decks burning like Roman candles. Those who fell overboard, or in their unspeakable agony threw themselves over the side, found that even this was not enough to staunch the flames. Instead, the afflicted men continued to burn in the water, their blackened bodies bobbing around in the sea like so many cloves of burned garlic.
As the Byzantines directed the blasts of liquid fire onto the surface of the water, the sea itself caught fire, erupting into sheets of flame that roasted men alive, even as they swam for their lives in mortal terror. For the Saracen fleet, there was neither victory nor escape as one by one their ships were transformed into floating bonfires, burning hulks that slipped, smoldering, beneath the waves. To the Saracen host who died that day, it must have felt as if the very fires of Hell had been unleashed against them. God, it seemed, was not on their side after all.
This was Islam’s—and the world’s—first introduction to that most awesome and mysterious weapon of the Byzantines: Greek Fire.
The Atomic Bomb of the Ancient World
In and of itself, of course, the many destructive ways in which fire can be put to use was actually nothing new, even to the world of ad 678. Its use is as old as war itself. Scenes depicting fire in battle have been found on Assyrian bas-reliefs. The Egyptians also used fire, as did the ancient Greeks and the Romans. Over the centuries, a variety of concoctions containing some combination of sulfur, bitumen, rosin, naphtha, pitch, charcoal, tallow, turpentine, saltpeter, and crude antimony would all make their appearance on the battlefield. In naval warfare, wooden and clay pots filled with these volatile mixtures were set alight and either thrown or catapulted onto the decks of enemy ships. True Greek Fire, however, as the Saracens discovered in 678 and again in ad 718, when a second massive invasion fleet met the same grisly fate as the first, was an entirely different animal altogether.
True Greek Fire was a “wet fire” that could be concentrated, controlled, and directed at will with all the destructive force of a modern flamethrower of the sort used by American marines in the South Pacific during World War II. For the warriors of the 7th century, however, and of the next several hundred years, the awesome destructive power of Greek Fire—and of its psychological impact on the enemies of Byzantium—would have been equivalent to that of a modern atomic bomb.
