Be audacious and cunning in your plans, firm and persevering in their execution, determined to find a glorious end.
Carl von ClausewitzTo be practical, any plan must take account of the enemy's power to frustrate it.
Carl von ClausewitzIf we do not learn to regard a war, and the separate campaigns of which it is composed, as a chain of linked engagements each leading to the next, but instead succumb to the idea that the capture of certain geographical points or the seizure of undefended provinces are of value in themselves, we are liable to regard them as windfall profits.
