This translation of Johann Ewald's classic essay, Abhandlung Uber den kleinen Krieg, published in 1785, describes light infantry tactics in an era of heavy infantry formations. Robert Selig and David Skaggs comment on Ewald's treatise on partisan warfare and its relevance to current military doctrine. They also provide extensive scholarly notations with the text, explaining people, places, and events during the Seven Years' War and the American Revolution, where Ewald had extensive experience as a company commander in the Hessian Field Jaeger Corps. This first English translation should be of real interest to historians of American Revolution and pre-Napoleonic warfare and of special use to military professionals today in the Army and Marine Corps. Captain Ewald, eventually a Major General in the Danish Army, describes the recruiting and training of light infantry troops, and discusses their use both in the Seven Years' War and the American Revolution at length. He provides illuminating insights into light infantry tactics and doctrine.
