"Diary of the American War: A Hessian Journal" by Johann Ewald (often rendered in older English editions as “Captain Johann Ewald”) is a first-hand memoir describing the experience of a German officer serving in North America during the American Revolutionary War.
The work is based on Ewald’s contemporaneous journal entries while serving as an officer in troops drawn from the Landgraviate of Hesse-Kassel, which were employed by Great Britain under subsidy agreements. It provides a detailed eyewitness account of campaigns, marches, battles, and daily military life.
A central focus is the operational experience of light infantry and rifle units, including reconnaissance, skirmishing, and irregular warfare tactics used in the varied terrain of North America. Ewald describes engagements in theaters such as New York, New Jersey, the southern colonies, and later stages of the war.
The journal also highlights the practical realities of campaigning, including logistics, discipline, supply shortages, weather, and the challenges of coordinating with British command structures across a vast and unfamiliar continent.
Another key theme is the perspective of a professional German officer serving abroad, offering insight into military culture, training, and the adaptation of European troops to colonial warfare conditions.
