"A Dirty, Trifling Piece of Business: Volume 1: The Revolutionary War as Waged from Canada in 1781" by Gavin K. Watt is about the English/Tory/Native American offensives in New York and New England during 1781.
Gavin Watt is a Canadian historian who has written extensively about Canada in the American Revolution. I have been very impressed with his writings and endeavor to read his books when I have a chance. I find his writing quite readable and his works thoughtful, well considered and, when I have looked, quite accurate. Additionally, he writes from the perspective of the English side, which to this US reader is rarely encountered. I highly recommend his work.
I brought his book on St Leger's Campaign with me when I walked the Oriskany battlefield. The National Park Ranger there and I discussed Watt's observations and how they related to the current view of where the battle occurred. The ranger seemed to feel that certain of Mr Watt's observations deserved further investigation.
I would highly recommend this book to anyone interested in learning about what happened in the western areas of New York and New England during the campaign of 1781. And I would highly recommend all of his works to anyone interested in the American Revolutionary War in New York and New England.
