IIRC (if I recall Clausewitz), the context of war is important: what political/diplomatic goals are at stake? What is the terrain? What specific forces are available, what is the quality of their leadership, and how is their overall morale? etc. In the abstract, only questions like “what happens when a dragon uses a breath attack against a tank?” can be asked, and since this is imaginary, the answer is: whatever you want.
