Discourses on Livy

Whether when invasion is imminent it is better to anticipate or to await it.

I have often heard it disputed by men well versed in military affairs, whether, when there are two princes of nearly equal strength, and the bolder of the two proclaims war upon the other, it is better for that other to await attack within his own frontier, or to march into the enemy's country and fight him there; and I have heard reasons given in favour of each of these courses.
