In the UK an Europe there was an is a lot of covert shooting. This means following the dog into thick stuff. No driven game at one time, no battues.
A sportsman had to dress for this thick and prickly stuff, and had to carry his own game most of the time, unlike field shooting, where horses were used for "charging the coveys" as Hawker would say.
In open country the game could be picked up and put in the game cart on larger shoots, but many gentlemen shot on their own, or in a friends company, and had to carry what they shot.
Hunk of cheese and bread, and a raw onion in the pocket for a mid day respite.... all good sport!
