Well, as for one element of your question, Britian didn't have a military education to offer to officers!
Welly trained in France, at Angiers, I think it was. (Someone will correct the city, if I've got it wrong.) In fact, a number of British officers, or officers-to-be, got a bit of training in Europe as a part of their early education. The Royal Military College (eventually to become Sandhurst) was not established (and after an up-hill struggle) until the French Revolutionary and Napoleonic Wars (turning to a Frenchman to fill the key teaching post). But it was very small, and really had only the capacity for an annual handful of graduates each year. There were other, technical schools, for the artillery, for example, but for general military education for a British officer, it was self-directed study, or the Continent!
But I agree, it would be interesting to know the list of books he took :o)
