"I was very troubled at that time," he said, "for Saruman was hindering all my plans. I knew that Sauron had arisen again and would soon declare himself, and I knew that he was preparing for a great war. How would he begin? Would he try first to re-occupy Mordor, or would he first attack the chief strongholds of his enemies? I thought then, and I am sure now, that to attack Lórien and Rivendell, as soon as he was strong enough was his original plan. It would have been a much better plan for him, and much worse for us.
"You may think that Rivendell was out of his reach, but I did not think so. The state of things in the North was very bad. The Kingdom under the Mountain and the strong Men of Dale were no more. To resist any force that Sauron might send to regain the northern passes in the mountains and the old lands of Angmar there were only the Dwarves of the Iron Hills, and behind them lay a desolation and a Dragon. The Dragon Sauron might use with terrible effect. Often I said to myself: "I must find some means of dealing with Smaug. But a direct stroke against Dol Guldur is needed still more. We must disturb Sauron's plans. I must make the Council see that.'
