"There must be unity of purpose. There can be no success without it. I earnestly entreat you, be in no doubt upon that point. I am not. If I cannot have your wholehearted support, it is wrong for me to assume the terrible responsibility of leadership in these times. I am willing to go on, if you make it possible for me still to serve you. But if there is anyone better able to do so, I shall gladly make way for him. And it is your duty to yourselves to support him, and not me. Your country’s future is at stake. This is no time to indulge your personal prejudices or fancies. Carefully and calmly, look well into the situation, then pick the man and the policy best fitted to deal with it, and resolutely back that man and that policy. The nation should range itself behind them. In war you fought as one; fight now again as one, for the task ahead demands your war-time resolution and your war-time unity."
