We actually sometimes get paid for participating in events (just a small sum to make it cheaper for us). Cavalrypeople usually get some money to pay for their horses too. From what I understand this is often about 1/3 of what you pay in total, and sometimes even more. Sometimes you get nothing, of course. But yeah, I never heard of an event where you had to pay to get in. And of cours we get powder. U jelly?
I know surrendering is fun, and I tried to do it a few times but people always just ignore or kill you. :/
These men (of the video) portray the Chasseurs-au-cheval de la garde imperiale, and they are one of the best cavarlyregiments in Europa. They and their horses (they always bring their own) are trained to a fantastic level. They even shoot from horseback in full gallop, which is (In NW re-enactment) rather uncommon. My group, for example, doesn't; simply because our rental horses aren't trained to do that, but it is actually not even known if Boreel did or did not have carbines during the Waterloo campaign.
