Sam had just wits enough left to thrust the phial back into his breast. 'Run, Mr. Frodo!' he cried. 'No, not that way! There's a sheer drop over the wall. Follow me!'
Down the road from the gate they fled. In fifty paces, with a swift bend round a jutting bastion of the cliff, it took them out of sight from the Tower. They had escaped for the moment. Cowering back against the rock they drew breath, and then they clutched at their hearts. Perching now on the wall beside the ruined gate the Nazg?l sent out its deadly cries. All the cliffs echoed.
In terror they stumbled on. Soon the road bent sharply eastward again and exposed them for a dreadful moment to view from the Tower. As they flitted across they glanced back and saw the great black shape upon the battlement; then they plunged down between high rock-walls in a cutting that fell steeply to join the Morgul-road. They came to the way-meeting. There was still no sign of orcs, nor of an answer to the cry of the Nazg?l; but they knew that the silence would not last long. At any moment now the hunt would begin.
'This won't do, Sam,' said Frodo. 'If we were real orcs, we ought to be dashing back to the Tower, not running away. The first enemy we meet will know us. We must get off this road somehow.'
'But we can't,' said Sam, 'not without wings.'
The eastern faces of the Ephel Dúath were sheer, falling in cliff and precipice to the black trough that lay between them and the inner ridge. A short way beyond the way-meeting, after another steep incline, a flying bridge of stone leapt over the chasm and bore the road across into the tumbled slopes and glens of the Morgai. With a desperate spurt Frodo and Sam dashed along the bridge; but they had hardly reached its further end when they heard the hue and cry begin. Away behind them, now high above on the mountain-side, loomed the Tower of Cirith Ungol, its stones glowing dully. Suddenly its harsh bell clanged again, and then broke into a shattering peal. Horns sounded. And now from beyond the bridge-end came answering cries. Down in the dark trough, cut off from the dying glare of Orodruin, Frodo and Sam could not see ahead, but already they heard the tramp of iron-shod feet, and upon the road there rang the swift clatter of hoofs.
'Quick, Sam! Over we go!' cried Frodo. They scrambled on to the low parapet of the bridge. Fortunately there was no longer any dreadful drop into the gulf, for the slopes of the Morgai had already risen almost to the level of the road; but it was too dark for them to guess the depth of the fall.
'Well, here goes, Mr. Frodo,' said Sam. 'Good-bye!'
He let go. Frodo followed. And even as they fell they heard the rush of horsemen sweeping over the bridge and the rattle of orc-feet running up behind. But Sam would have laughed, if he had dared. Half fearing a breaking plunge down on to unseen rocks the hobbits landed, in a drop of no more than a dozen feet, with a thud and a crunch into the last thing that they had expected: a tangle of thorny bushes. There Sam lay still, softly sucking a scratched hand.
