"It is this common danger which ought always to be kept in view as the true basis of the alliance, and which ought to preclude defection from the common cause. It must be represented to the Allies that having determined to deliver themselves from the vengeance of the conqueror by their collective strength, if collectively they fail, they are separately lost. He never will again trust any one of them with the means of self-defence—their only rational policy then is inseparable union—to make the contest that of their respective nations, to persevere under every disaster, and to be satisfied that to end the contest safely the enemy must be compelled to treat with them collectively, whilst the best chance of an early peace is at once to satisfy the enemy that a separate negotiation is unattainable."
