If I had time and anything like your ability to study war, I think I should concentrate almost entirely on the “actualities of war”—the effects of tiredness, hunger, fear, lack of sleep, weather…. The principles of strategy and tactics, and the logistics of war are really absurdly simple: it is the actualities that make war so complicated and so difficult, and are usually so neglected by historians. —Field Marshal Lord Wavell, in a letter to Liddell Hart
