A firsthand military journal and assembled wartime documents that follow a Continental regiment's operations during General Sullivan's 1779 campaign against western Indigenous settlements. The volume presents daily entries recording marches, camp life, combat actions such as the Newtown engagement and the Groveland ambuscade, logistical details, and lists of destroyed towns, accompanied by maps, a biographical sketch of the diarist, copious historical notes, and appended journals from other officers. The editorial apparatus contextualizes movements and battles while preserving original spellings and transcriber's notes for readers of primary-source material.
