As for the virtuous poor, one can pity them, of course, but one cannot possibly admire them. They have made private terms with the enemy, and sold their birthright for very bad pottage. They must also be extraordinarily stupid.
It is sufficient to estimate the enemy situation correctly and to concentrate your strength to capture him. There is no more to it than this. He who lacks foresight and underestimates his enemy will surely be captured by him.
