Bandon was a term used in the Byzantine Empire, which was a long time ago in a place called Constantinople. The Byzantine Empire had a big army, made up of different groups of soldiers. One of these groups was called the "bandoi", which means "bands" in Greek.
The Bandon were highly-trained soldiers who were organized into small teams or "bands". Each bandon had a leader, who was called a "bandon leader", and they worked closely together to protect their empire from enemies. They were like the superheroes of the Byzantine Empire!
These soldiers were known for their discipline, bravery, and loyalty. They would often fight in close formation with heavy weapons, like swords and spears. They were trained to fight in all kinds of conditions, from hot sun to freezing cold.
The Bandon were also very important because they were one of the main ways that the emperor kept control over the army. The leader of the Bandon was often the one who decided which soldiers would be promoted, and who would be punished if they didn't do a good job.
So, in short, the Bandon were a group of highly-trained soldiers who worked in small teams to protect the Byzantine Empire. They were strong, brave, and disciplined, and they played a very important role in maintaining order and protecting their empire from harm.
