The Defence of Duffer's Drift
In the 100 years since The Defence of Duffer's Drift was first published in Great Britain, the face of modern warfare has changed dramatically. But what have not changed very much are the concepts of small unit tactics: Ground is held, buildings are searched, and individual enemy combatants are killed or captured by men with rifles. And those same men are led by small unit leaders. The Defence of Duffer's Drift is a fictional account of a young, inexperienced British officer, who is tasked with holding a river crossing with 50 troops against a larger enemy force. His initial failures and eventual victory serve as an entertaining and instructive vehicle to convey the principles of small unit tactics. Because it deals with principles, this definitive work has endured to this day and is on the Commandant's reading list. This book causes you to think about tactical situations from a different point of view and question everything you do. Focus on the basics. Every Marine should read this at least once.

Major General Sir Earnest D. Swinton, K.B.E., C.B., D.S.O., was a noted English soldier, author and professor. Considered by Field Marshal Earl Wavell as one of the most far-sighted officers the British Army has produced, he wrote before World War I on the effects of air warfare, mining and of psychological warfare. In 1914, Sir Swinton completely revolutionized warfare by his invention of the tank; he, more than anyone else, was responsible for its introduction and development.
He served as Professor of Military History at Oxford from 1925 to 1939, and later as Commandant of the Royal Tank Corps from 1934 to 1938 - earning the rank of Major General.
As a Captain, shortly after service in the Boer War, he wrote "The Defence of Duffer's Drift," using the pseudonym, Lieutenant Backsight Forethought, or BF. Duffer's Drift has become a military classic on minor tactics in this century. In addition to Duffer's Drift, and contributing to many journals, he authored The Green Curve in 1909 and The Great Tab Dope in 1915, under the pseudonym O'le Luk-Oie (Olaf shut-eye). His other works include The Study Of War in 1926 and his final publication, An Eastern Odyssey written in 1935.
An electronic copy of the Defense of Duffer's Drift can be found on the U.S. Army Command and General Staff website.
