What did they do to spies in the Revolutionary War as torture?

The British received harsh treatment from the Patriots in many ways. One way is that the Patriots covered the British soldiers in hot tar and then goose feathers. They burned British townsfolk's houses down because they honored King George the third. They also threw rocks at his picture because they dispised him so much. Lastly, they made effigies (dummies) of him and burned them. They were not as cruel as you think that they were. You can be surprised sometimes.
