B.H. Liddell Hart1941
A classic book on strategy. While its main message can be stated in one sentence – always approach your goal indirectly – it's a combination of historical military analysis and a distillation of key ideas that can be applied both militarily and beyond. The discussion of First World War strategy is especially strong; the discussion of Hitler's strategy is interesting because it was written while the issue was still in doubt, and so can be criticised for its unreality (making a rational argument to Hitler's henchmen against their achieving final victory), but at least was not shy of making definite and supported suggestions.
I can't recommend this edition of the book, however. The typography and quality of the layout are terrible.
3/5. Finished 20 February 2019.
