War of Independence: 18th Century Warfare (1976)

From the preface:

These rules have been written as a companion set to the "Napoleonic, American Civil War and Colonial Warfare Rules" published by Leicester Micro Models. They are primarily aimed to reproduce the warfare of the American War of Independence in this bicentennial year and a section on Army Organisation for that period is included. They may equally well be used or European battles of the Seven Years War, or for the French and Indian War.
