(Hey there, newcomer here. If the following question isn't suited for worldbuilding, please let me know!)
So, I have the following situation:
There is a untouched, natural forest shaped as a circle with a diameter of a mile with some kind of invisible barrier around it. This is set in late spring / early summer with a temperature of 20°C. The forest contains everything a hunter could want to survive. Water sources, fire inflictint material and everything you can think of, that could be found in the nature. The forest contains normal wildlife. Rabbits, foxes, deer and so on.
In this forest are 100 equipped archers. 50 of them from the ~12th century, the other 50 coming from nowadays. All persons have the best archer equipment available at their time, but no other weapons besides a bow and some kind of dagger, which could be used for skinning animals and stuff like this.
All of the 12th century guys perfectly know the area, as if they hunted their whole life in this area.
The 21st century equipment, which would require satellites and other stuff that didn't existed in the 12th century doesn't work. So no GPS for example. And, of course, they don't know the area. They DO have a map of the area from our time, but it has most probably change in the last ~900 years. For example the water sources moved etc.
All 100 persons are on top of their hunter efficiency and, of course, trained archers. Just assume they are the best of the world at their respective time. All of them have a basic grip on surviving for multiple days in the wild. All 50 people coming from the same age work as a team.
All of them know, that they are in some kind of deathmatch. They can only leave the area, if all 50 persons of the other century are dead. After 28 days of "fight", all of them are going to die. It has to be settled until then.
All of them speak the same language, so no problems in this regard.
Everything above in short:
The 12th century guys know the area perfectly, while the 21st century guys (probably) have better, more modern equipment.
Here's my question: which side would be more likely to survive / kill the other?
Don't think about the number of arrows, just assume all of them have access to more than they can use.
Edit (because asked in the comments):
The 50 people were chosen based on being the most efficient for the task of killing the others. So, there are different types of people. For example: Hunters, which just hunted all their life in order to feed their families, as well as soldiers, which even have fought in medieval warfares.
At the start of the deathmatch, all 100 persons "spawn" randomly inside the area. The teams do NOT start as a group at one point. Thus, while the 12th c. guys perfectly know the area and can immediately search good places to hide and start to hunt the 21st c. guys down, they - the 21st guys - do not know the area (besides their map, which they haven't studied yet).
