I thought Thomas Wilkinson made a great Cornwallis in Mel Gibson's "The Patriot." His begrudging quote delivered at Yorktown said everything about the founding of the USA...
"Everything will change. Everything has changed."
Could not agree more...whenever I see Cornwallis' name, I think of him...
And in a similar vein, when the surrender was presented at Saratoga, the Brit band played "The World Turned Upside Down."
