“A half-million?” Honor repeated, and Mayhew nodded.

“At least,” he repeated. “Remember that they’ve been dumping what they considered to be their real hard cases here for eighty T-years, My Lady. We’ve got fairly hard numbers on the military POWs they’ve sent here. Most of them are from the various star systems the Peeps picked off early on, from Tambourine to Trevor’s Star. You had to be a pretty dangerous fellow to get sent to Hell, of course—sort of the cream of the crop, the kind of people who were likely to start building resistance cells if you were left to your own devices. Of course, if State Security had been running things at that point, they probably would’ve just shot the potential troublemakers where they were and saved themselves the bother of shipping them out here.

“At any rate, there weren’t very many additions to the POW population for about ten years before they attacked the Alliance, and the nature of the POWs sent here since the war started is a bit different from what I’d expected.” Honor raised an eyebrow, and he shrugged. “If I were StateSec, and I had a prison whose security I felt absolutely confident about, that’s where I’d send the prisoners I figured had really sensitive information. I could take my time getting it out of them, and I’d have complete physical security while I went about it—they couldn’t escape, no one could break them out, and for that matter, no one could even know that was where I had them, since the location of the system itself was classified. But StateSec apparently prefers to do its interrogating closer to the center of the Republic, probably on Haven itself. Instead of using Hell as a holding area for prize prisoners, they’ve been using it as a dumping ground. People who make trouble in other camps get sent here, where they can’t get into any more mischief.”

“What sort of ‘mischief’ were they getting into?” McKeon asked in an interested tone.

“Just about anything you can think of, Sir,” Mayhew replied. “Escape attempts, for a lot of them… or else they were guilty of being the kinds of officers and noncoms who’d insist on maintaining discipline and unit cohesion even in a prison camp. The troublemakers.”

“And they’ve been skimming them off and dumping them here, have they?” Honor murmured, and there was a wicked gleam in her good eye. “You could almost say they’ve been distilling them out of the rest of their prison population, couldn’t you?”

“Yes, My Lady, you could,” Mayhew agreed. “According to the best numbers Scotty and I could come up with, we figure there are between a hundred eighty and two hundred thousand military prisoners down here. It could run as high as two hundred and fifty, but that’s a maximum figure. The other three or four hundred thousand are civilians. About a third of those were shipped out after various civilian resistance groups from conquered planets were broken up, but most are the more usual run of political prisoners.”
