History of the Peloponnesian War

Nor are you so behind the enemy in experience as you are ahead of him in courage; and although the science of your opponents would, if valor accompanied it, have also the presence of mind to carry out at an emergency the lesson it has learnt, yet a faint heart will make all art powerless in the face of danger. For fear takes away presence of mind, and without valor art is useless.

Against their superior experience set your superior daring, and against the fear induced by defeat the fact of your having been then unprepared;

remember, too, that you have always the advantage of superior numbers, and of engaging off your own coast, supported by your heavy infantry; and as a rule, numbers and equipment give victory.
