when were hand grenades first used in war
Grenade Rudimentary incendiary grenades appeared in the Eastern Roman (Byzantine) Empire, not long after the reign of Leo III (717–741).[4] Byzantine soldiers learned that Greek fire, a Byzantine invention of the previous century, could not only be thrown by flamethrowers at the enemy, but also in stone and ceramic jars.[4] Later, glass containers were employed. The use of Greek fire spread to Muslim armies in the Near East, from where it reached China by the 10th century.[4]
