The Year of the Hangman (1777) ended in the first third of this very dry book. While true that the Iroquois' semi-alliance with the British started this year, the main focus of this book is the Battle of Wyoming (1778) and the punitive Sullivan Expedition (1779) that followed. While the latter was under George Washington's orders, I hardly agree with the cover subtitle "George Washington's Campaign Against the Iroquois".
The text was factually complete but very dry, illustrations (always on the upper right hand page) inserted sparsely, and the chapters unbroken except into paragraphs. Further breaking into sections (even one blank line) would have facilitated transitions between the British and Continental points of view, which were difficult to follow - especially since each side had Butlers and Clintons. Maps were unremarkable and scarce.
I would not recommend this book to anyone.
