birched

The victims had first to go out into the woods to gather the branches with which later they were to be birched.

The three boys wandered away as far as Acle, eleven miles from Norwich, whence they were ignominiously brought back and birched. 

They say his head was shaved; he was birched like a schoolboy by Morse's peons; he was branded, tarred and feathered, and turned contemptuously adrift.

He did not get the reception he expected, for, in dire wrath at the imputation that he was deaf, Mr. Quirk birched the informant soundly.

If they did something wrong they would be publicly birched -- a collection of birch branches tied together would be used.
