In both the AWI and the ACW the "rebels" had an advantage on POW treatment in that during the early days of the conflict they were successful in obtaining a number of POWs that could be held as hostages, thus insuring that their own POWs would be treated as POWs rather than as traitors.
I think that prison camps in America preceded Burgoyne's surrender. A great many American POWs were kept in hulks in NY harbor, and the Americans kept a fair number of Brits and their supporters in various facilities throughout the country. As for the ACW, the conditions on both sides, while never ideal, deteriorated significantly after Grant stopped the POW exchanges.
No problem, Brian...
As I wrote I don't feel resposable for what italians did years before my birht! And I'm not just talking about the last war: I coud go back to the colonial wars too, and the piedmontese "invasion" of southern Italy, down to romans and etruscans!!
There is an italian "core" in all the people who lived this country in the past, but I don't agree with anything they did of course; they're not "me" so I don't feel hungry if someone offends them.
Useless to say that that anyone should understand that later italians are different from the former... just like in any country!!
