its not absurd to think of a knight retinue. While the game is not direct talk about them it would make no sense to gnore this reality.
Full armor is impossible to use on your own. You do need squires and people to take care of all that stuff. Armor, oil, taking care of the horse, making food, etc.
And they would also help the knight and where the people he could trust above any other to deliver message, give orders, etc.
So a single knight is usually 2 to 10 people plus a horse or two. As more people you bring more food/stuff you need.
if you get your king to go to battle you can be sure he can have up to 100 persons tending to him, his armor, weapons, tent, horses, etc.
Keeping his status, even during a march or battle was kind of necessary to keep all the myth about him being above the others.
