"An advocate, by the sacred duty which he owes his client, knows in the discharge of that office but one person in the world, that client and none other. To save that client by all expedient means, to protect that client at all hazard and costs, to all others, and among others, to himself, is the highest and most unquestioned of his duties; and he must not regard the alarm, the suffering, the torment, the destruction which he may bring upon any other. Nay, separating even the duties of the patriot from those of an advocate, and casting them, if need be, to the wind, he must go on reckless of the consequences, if his fate it should unhappily be to involve his country in confusion for his client's protection."  *
