‘I hardly minded the pain,’ he says. ‘We have all had, saving you sir, as much if not worse from our fathers.’
‘True,’ he says. ‘My father beat me as if I were a sheet of metal.’
‘It was that he laid my flesh bare. And the women looking on. Dame Alice. The young girls. I thought one of them might speak up for me, but when they saw me unbreached, I only disgusted them. It made them laugh. While the fellow was whipping me, they were laughing.’
— Wolf Hall by Hilary Mantel
What is the meaning of "unbreached"? In the dictionary it says "not breached; intact", but I can't work it out in the sentence.
