12) Military Operations Macedonia: From the Outbreak of War to Spring 1917, by Captain Cyril Falls

Wonderful that the Imperial War museum has reprinted this volume (originally published in 1931), though it’s a shame that we lose out on the full-colour maps. Certainly the most comprehensive guide you’ll find, yet very dense – I might well have given up on my little research project (to be written up in more detail later) if I had started here instead of with Wakefield/Moody, Palmer and Price.
