Elfwine: Thank you. I was trying to create an army that could credibly pose a very serious threat to Timur, like the OTL Ottoman army. And I really like your last line.
Welcome.
Personally, I would say in all seriousness that the Byzantines have a very good chance assuming capable leadership. They have a well trained, well disciplined army made up of all arms and a good sense of the value of archery (especially horse archery), including knowing how to counter enemy horse archery.
But Timur is being built up to being a tough foe, and the Byzantines are getting over (or not) some very ugly politics, so the complications from those will seriously undermine an abstract calculation of the odds.
Still, if you want the Byzantines to win, it would be very plausible. And if they lose, there are very plausible scenarios for that.
Thus my last line. Not to mention that this kind of battle is inevitably going to be bloody - win or lose, this is going to be one of those rare and avoided-for-good-reason (you've probably studied Byzantine history enough to know why) Decisive Battles.
So, very intriguing.
By the way, one doctor for every 20 soldiers? That's a lot of doctors. Someone has obviously been working hard on this.
Good thing too, but very impressive. As is the economy to support 90,000 men like this.
The Byzantium we know and adore. Its like a 19th century state with medieval technology.
No cannons yet, I see. Or are those still in the Sluggish Siege Machine category that the field army drags with it only when needing that much firepower (given that trebuchets are usually sufficiently nasty)?
