The Riders of Rohan arrive, Merry is with them

When the dark shadow at the Gate withdrew Gandalf still sat motinless.

But Pippin rose to his feet, as if a great weight had been lifted from him;

and he stood listening to the horns,

and it seemed to him that they would break his heart with joy.

And never in after years could he hear a horn blown in the distance

without tears starting in his eyes.
