Excerpt from Aircraft in Warfare: The Dawn of the Fourth ArmThe subject of "Aircraft in Warfare," with which Mr. Lanchester deals, is, and for some time will be, highly controversial. In each of its three aspects, the scientific, the military, and the material or manufacturing, it is still in the stage of experiment and speculation. The results obtained cannot always be made available for the information of the general public, and those which are available have usually been set forth in terms so technical, either in a scientific or a military sense, as to be somewhat difficult for the general reader to understand. Very little trustworthy information, therefore, has been disseminated, and the uninstructed public, hungry for information on a novel and alluring subject, of which the national importance is evident, has fallen an easy prey to the imposter. Any plausible rogue, gifted with sufficient assurance, and aided by a ready pen or supple tongue, has been able to pose as an "aeronautical expert," and to find some kind of following.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

From Scientific American F. W. Lanchester was one of the pioneers of the circulation theory of lift and for that reason is one of the most respected figures in aviation.
From The New Yorker F. W. Lanchester is an important figure in the history of science of military strategy. His equations of combat described in this book are the foundations of the science of Operations Research (OR). Lanchester is also honored by the annual Lanchester Prize awarded by the Operations Society of America
Review F. W. Lanchester is an important figure in the history and science of military strategy. His equations of combat described in this book are the foundations of the science of Operations Research (OR). Lanchester is also honored by the annual Lanchester Prize awarded by the Operations Research Society of America. -- Dr. J. G. Taylor, Professor of Operations Research, Naval Postgraduate School, Monterey, CaliforniaF. W. Lanchester was one of the pioneers of the circulation theory of lift, and for that reason is one of the most respected figures in aviation. -- Dr. John Anderson, Department of Aerospace Engineering, University of MarylandSuch was the genius of F. W. Lanchester that his work was often too far-reaching for his contemporaries to fully understand. Indeed, his profound first principles of flight in the early 1980s led to his being advised most strongly that, should he publish those theories, his reputation as a sane engineer would be ruined. Thankfully his work lives on today as this new edition of his legendary "Aircraft in Warfare." -- C. S. Clark, Lanchester Historian, Author of the Lanchester Legacy, Volume 1 and 2, on the life, times and inventions of F. W. Lanchester and his brothers

It goes like this. There is a battle between two armies, one with A soldiers and one with B soldiers. Each army has a constant efficiency coefficient (determined by weaponry, training, etc.): a side A soldier takes out a enemies per unit time while a side B soldier takes out b enemies per unit time. The battle is then described by the differential equations dA/dt=-bB and dB/dt=-aA. Dividing the first by the second gives aAda = bBdb, which we integrate to get aA^2-bB^2=constant. (Lanchester avoids mentioning integration and uses a direct infinitesimal argument.) The sign of this constant determines the outcome of the battle, since if, for example, there are side A troops still standing when B reaches zero then the constant must be positive (indeed we see that the number of side A troops surviving the battle can be calculated by setting B=0 and solving for A). Also, the fact that the strength of an army is proportional to the square of its size has an important strategical implication: never divide your forces. For example, assuming equal efficiency a=b=1, an army of 5000 could handle an army of 7000 split into two, 5000^2=4000^2+3000^2, but if the 5000 army faced the full 7000 army at once it would be destroyed after having killed only about 2100 enemies, 7000^2-5000^2=4900^2.

Revolutionary for its time By David Christhilf This historical book (1917) documents revolutionary insight for its time into how to make effective use of aircraft in warfare. Although hardware capabilities and operational tactics have changed over the years, many observations about the strategic importance of aircraft are still valid today. The "Lanchester Equations" for battlefield attrition are based on a model that damage between opposing forces occurs primarily along lines of contact rather than in depth, which was representative of warfare when the book was written. Modeling combat using differential equations continues to be an aspect for theater level simulations in modern warfare. The analysis in the book represents a considerable improvement over the prevailing views at the time concerning the limited importance of aircraft in warfare.

Here Lanchester advances his N-Square Law, which has become what we now refer to as Lanchester Equations. The interest of the book is its historical value, as better presentations are to be found elsewhere. There are other interesting portions of the book beyond the mathematics, such as "aeroplane versus dirigible." The book's value is as a historical record of both the advent of military aviation and military operations research.
