Great ambition is the passion of a great character. Those endowed with it may perform very good or very bad acts. All depends on the principles which direct them.
The keys of a fortress are always well worth the retirement of the garrison when it is resolved to yield only on those conditions. On this principle it is always wiser to grant an honorable capitulation to a garrison which has made a vigorous resistance than to risk an assault.
Unity of command is essential to the economy of time. Warfare in the field was like a siege: by directing all one's force to a single point a breach might be made, and the equilibrium of opposition destroyed.
