No, knighthood isn’t automatic for the nobility. There are accounts of kings knighting dozens or hundreds of young nobles just before the big battle. All the nobility were eligible for knighthood, though, even if they never got knighted.
From an unknown source: It’s quite simple; you have two sides, one out in the field, one in. Each man on the side that’s in goes out, and when he’s out he comes in and the next man goes in until he’s out. When they’re all out, the side that’s been out in the field comes in, and the side that’s been in goes out and tries to get out those coming in. If the side that’s in declares, you get men still in not out. Then when both sides have been in and out including not outs, twice, that’s the end of the match. Now do you see?
I had a cat who shed in solid sheets of fur. Come spring, the old fur was pushed out by the new fur, moving further and further from his body. It made him armor plated until it was far enough from his body for me to snip it free with scissors, very carefully.
