The National School started the sport of polocrosse, as an exercise for its young riders. The game was played indoors with two players per side, with sticks made from old polo sticks with the mallet end replaced with a squash racket head with a net. To score a goal you had to scoop the ball up from the field and drop it in the goal. The game was brought to Australia in 1938, and the Australians picked it up and ran with it, as you can see in the video at the end of the piece. Here in England, matters remained much more sedate. The National School of Equitation's first attempts at advertising the new sport in March 1938 were a tad stilted: none of those ponies look to have moved for at least the last half an hour.
It's such grand fun everyone's been petrified. Things did improve, and by May 1938, there was a little more action:
Polocrosse now looks like this clip below - before you watch it, all horses and riders do survive, though the video is quite alarming at times! Apologies for the fact this video slipped off the first draft. Not quite sure what happened there.
