In a battle, as in a siege, the art consists in concentrating very heavy fire on a particular point. The line of battle once established, the one who has the ability to concentrate an unlooked for mass of artillery suddenly and unexpectedly on one of these points is sure to carry the day.
In war, as in politics, no evil - even if it is permissible under the rules - is excusable unless it is absolutely necessary. Everything beyond that is a crime.
What is the future? What is the past? What are we? What is the magic fluid that surrounds us and conceals the things we most need to know? We live and die in the midst of marvels.
