UK: Cavalry at Sandhurst

Tent pegging is a race, usually a team race or relay, where a rider and horse aim to knock down a peg with a stick, or pick up a peg on a lance, as fast as possible. This historically emerged from the attacks by Arabian Muslim cavaliers on enemy camps at dawn or late night, where they would gallop to their tents and pluck out the pegs of their tents and setting them alight, so that these would collapse on them, thus causing havoc and terror in the camp.
