They skirmished in open formation, and attacked in great masses. They developed efficient mobile artillery that could support infantry at all phases of combat. They broke armies up into smaller units that could operate more flexibly and independently. And they solved the problem of supplying huge armies by getting soldiers to live off the land. Napoleon became the master of initiative, concentration and surprise.
Every war is the product of deliberate, calculated decision.
No war is ever conducted without political purpose. Men do not fight because they are of a particular culture or sex, but because they are the instruments of reasoned and deliberate policy. If you want to understand war, look at politics. The Enlightenment belief that war was a rational human activity has been superseded by the twentieth-century prejudice that war is guided by the inhuman and the insane. It is not hard to understand why modern theorists want to deny the deliberate character of modern warfare.
