Niccolò Machiavelli,
The Art of War — Book 6
(1675)
“ There is nothing more imprudent or more perilous to a Captain than to wage war in winter, and more dangerous to him who brings it, than to him who awaits it. The reason is this: all the industry used in military discipline, is used in order to be organized to undertake an engagement with your enemy, as this is the end toward which a Captain must aim, for the engagement makes you win or lose a war. Therefore, whoever know how to organize it better, and who has his army better disciplined, has the greater advantage in this, and can hope more to win it. ”
