In any battle, great or small, the most insignificant of terrain and the most worthless of ground can for minutes, or perhaps hours, become so valuable that the blood of heroes and the wealth of an army's supply does not outweigh it. The true general knows when such a price is worth spending, and when the butcher's bill is sheer folly to pay.[1]
