Encyclopedia of Military History

Long before the internet, people used to write (and read) encyclopedias. I still have a few in my house, including a Funk & Wagnalls (as in “look that up in your Funk & Wagnalls”). Just saw a twitter post yesterday that referenced Dupuy & Dupuy’s Encyclopedia of Military History: Paul Poast on X: “To identify war outcomes, Stam’s study drew on military histories, notably the encyclopedic volume by Dupuy & Dupuy (cc @dupuyinstitute). https://t.co/oGJR4ZZuNQ” / X (twitter.com)

This was apparently part of a thread Dr. Paul Poast had on coding victories. As he notes, in a “pioneering work on war outcomes by Alan Stam” (Paul Poast on X: “This can be seen by considering the pioneering work on war outcomes by Alan Stam. https://t.co/8R6IY1JQOd” / X (twitter.com)), he drew heavily on Dupuy & Dupuy’s Encyclopedia of Military History. Now, that is gratifying. I am not familiar with Allan C. Stam and his work. In fact, this is the first I have heard of it (I do not get out much). It was first published in 1996. But, as they are referencing Trevor Dupuy’s work, I figured I should at least mention it in a blog post.
