Pippin awakes from a “swift moving dream in which he had been wrapped so long since the great ride began”. Shadowfax, the mightiest of horses, is rushing through Anórien, the most northerly region of the land of Gondor, bearing Gandalf and Pippin towards Minas Tirith and towards war. It is the third night since Pippin looked into the Stone of Orthanc and so was forced to endure the gaze of Sauron. Now the Dark Lord believes that a hobbit is at Isengard. He gloats ravenously at him. Is this the one who has the Ring?
Sauron is so overcome by his own anticipation that he does not wait to ask further questions. He has servants who can reach Isengard swiftly and bring the prize to him. When he has the Ring there will be no further need for questions and ample time to punish the creature who has kept it from him.
And so by a lack of curiosity Sauron gives his foes just a little time for action. Gandalf siezes the time, removing Pippin from the palantir and from the place that the Dark Lord believes him to be, and rushing as fast as possible towards the place of crisis where the battle must be fought. So too do Aragorn, Legolas and Gimli; they must find their way to Minas Tirith as quickly as they can. And so too must the hosts of Rohan and messages are sent far and wide by Théoden, their king, calling them to gather at Dunharrow. All must reach Minas Tirith in time for if the city of Gondor falls then even if Frodo is able to succeed in his mission and the Ring is unmade in the fires of Mount Doom there will be nothing to save and Frodo can go no faster than his feet can carry him and his burden will permit him. On the night on which Pippin gazes at the moon setting in the west Frodo watches it from the refuge of Henneth Anûn. He has far yet to go.
Wisdom trains us, through life and hard experience, that there are times when we can do nothing but wait; times when we must labour patiently, perhaps hoping against hope; times when we must get up again after failure and defeat; and then there times when we must grasp the slimmest of chances as swiftly as we can when they are presented to us. Gandalf has known all of these. He has laboured over two thousand years, bearing Narya, the Ring of Fire, to keep hope alive in the hearts of the free peoples of Middle-earth and in all that time he has been forced to wait as Sauron has grown in power. He has been the captive of Saruman in Orthanc, watching helplessly as the Nazgûl seek for the Ring. He has been a beggar at the gates of Théoden, forced to endure the humiliations of Wormtongue. He has even journeyed through death after the battle with the Balrog of Moria. Now there is a moment, just the briefest of moments, when he can act and even now it may be too late.
We must live our lives with our eyes open, watching for moments of opportunity. It may be given to a few to know that these are of great significance in the history of an age. They are like Simeon and Anna in the temple in Jerusalem looking for the coming of the Messiah. But all of us are called to be people of hope like them and while we wait for the dawning of the day we are called to do the acts of mercy in the knowledge that each one of them brings that dawn nearer. And we must do them most of all when it seems that the night is darkest.
