There are three boxing rings on the larger maps (Vatican / Gizeh / Sukhothai), each with three opponents. To enter a boxing ring, you need the correct disguise, which you can find on the map. (below more) - I was playing on moderate setting, just as information.
Some general tips for boxing:- Try to create a save with full health close to the boxing ring; reload is faster as the animation + heal yourself after each boxing fail. Around each boxing ring are save spots (Vatican in the passageway to the main square, Gizeh left and right on the street before the boxing house, Sukhothai when you leave the boat mostly).
- Each boxing ring has unlimited bandages; even if you do not want to fight, you can heal yourself there for free.
- Boxing is NOT button smashing; don't do this or you lose very quickly.
- The best strategy is parry + punch (1-3 hits depending on the opponent) and repeat.
- To replenish your stamina during fights, you simply have to parry your opponent's blows without hitting or countering them.
- With medicine bottles, you can purchase books for my stamina and health, which makes fighting a lot easier. You can also purchase books in the boxing rings to combine two health bars into one, which provides better regeneration (not fully depleted health bars regenerate).
Vatican
1 = Boxing Ring Location, 2 = Blackshirt Disguise Location
Disguise (Blackshirt):You can get the Blackshirt disguise at the earliest after you have met Gina for the first time in the game. After the cutscene, you will find yourself in the area where the disguise is located. Unfortunately, there can be a slight misunderstanding here; the developers want you to use the zipline that is in front of you but have forgotten that it is easy to overlook, and many players go back the way they came, which means that the area with the disguise is not unlocked by the player (after the zipline, you go through a door that can only be opened from the side).
The solution to this is that you have to go back to the cutscene point yourself to use the zipline and unlock the area/door. In spoiler below is a video how you can do this.
Fights:As mentioned at the beginning, the key to victory is always parrying when the opponent strikes and countering with subsequent strikes. With the first opponent, you can do 3-4 hits after parrying and then wait for him to strike again. The same with the second opponent. In the third fight you have to pay attention to your stamina (if you don't have any upgrades). The opponent will do more damage, and you will have to parry and strike perfectly more often.
Video:If needed, there is my video; it shows the disguise location and all three fights.
Gizeh
1 = Boxing Ring Location, 2 = Wehrmacht Disguise Location
Disguise (Wehrmacht):The area where the disguise is located is unlocked automatically during the story in Gizeh. The disguise is located in the watchtower. Climb up the watchtower on the left, then climb over to the right, enter through the window, subdue an enemy, and climb down the ladder, where you will find the disguise on the table.
Boxing Ring Location:From the vendor where you have to buy the lighter (part of the story), you can see a staircase to your left. Go there, follow the small path to your right, and you will see a door with two people standing in front of it; that's the boxing ring.
Fights:The fights here are more difficult, and you need to be good at parrying. Of course, the process is the same again: you wait until your opponent strikes, parry the blow, counterattack, and strike 1-2 blows yourself. Then repeat the process.
The third fight only worked for me if I only struck once after parrying; otherwise, the opponent just beat me up. So if you have problems, parry, counterattack, and strike at most once and then wait again.
Video:If needed, there is my video; it shows the disguise location and all three fights.
Sukhothai
1 = Boxing Ring Location, 2 = Royal Army Disguise Location
Disguise (Royal Army):The disguise is located in Voss' Camp, which is in the north of the map. You do not need any story progress. At the beginning of the story, the game takes you to the camp to loot Voss's vault, so it would be a good idea to take the disguise with you once you are there
Boxing Ring Location:The boxing ring is located in the east above the village and cannot be missed with the boat.
Fights:For the last three fights, I recommend that you level up your stamina and health to the maximum with the medicine bottles / books; otherwise, the battles will be almost impossible. The enemies hit super hard.
In the first two fights, as always, parry, counter, and hit back a maximum of 2-3.
Fight three is also the same BUT you need patience and a nearly perfect parrying! Don't try to end the fight as quickly as possible. Instead, parry several times, regenerate your stamina, and then strike back after parrying again. Very importantly, the opponent is super fast when it comes to surprising you while you strike. Again, attack a maximum of 2 times after parrying and then prepare to parry again. If you attack more often, the opponent will usually knock you down directly with a three-hit combo. Avoid this!

Medicine Bottles
As mentioned at the beginning, you can increase your stamina and health with the help of the medicine bottles. You can exchange the bottles for books in all three large areas. If needed, here are my collectibles videos for the bottles.
