battue

https://books.google.com/books?id=GoQCAAAAYAAJ&pg=PA203 page 203 In battue, whenever a hen rises, the signal "ware hen!" is called out by the sportsman or beater who is nearest it: meaning thereby "beware of the hen;" or, literally, "do not shoot the hen pheasant." In most places where game is very strictly preserved, and the rules of sporting firmly adhered to, a fine is imposed on any one who kills a hen pheasant in battue. […] https://books.google.com/books?id=GoQCAAAAYAAJ&pg=PA204 page 204 No dogs need be used in battue, but beaters only: and it should be remembered that pheasants always run to the end or side of the cover before taking flight, unless they are much pressed: consequently the best sport always comes at the extreme end of the wood.

The battues have nothing whatever to do with the poaching, and once sufficiently grand battue would put an end to poaching altogether, by destroying all the game. The evil of which the chancellor should have spoken, is the excessive game preserving which allows of battues, or great massacres. The game is preserved till it swarms, and then it is slaughtered in swarms; but it is clearly not the massacre which provokes the poaching, but the temptation of the extraordinary abundance of game.
