History of the Peloponnesian War

‘Peloponnesians and allies, our fathers made many campaigns both within and without Peloponnese, and the elder men among us here are not without experience in war. Yet we have never set out with a larger force than the present; and if our numbers and efficiency are remarkable, so also is the power of the state against which we march.

We ought not then to show ourselves inferior to our ancestors, or unequal to our own reputation. For the hopes and attention of all Hellas are bent upon the present effort, and its sympathy is with the enemy of the hated Athens.

Therefore, numerous as the invading army may appear to be, and certain as some may think it that our adversary will not meet us in the field, this is no sort of justification for the least negligence upon the march; but the officers and men of each particular city should always be prepared for the advent of danger in their own quarters.
