Into the empty space left by her leaving came the sound of horses and men's voices.

There was a sound of horses, and a commotion outside.

Another time it seemed to him that he heard the sound of horses rushing toward them, very near.

In the distance he heard the sound of horses, traveling fast.

After the last sound of horses faded, he tried to get his small party moving again.

She stopped frequently to listen for voices or the sound of horses.

The sound of men and horses not very far away broke the spell.

Far up the pass behind them they heard the sound of horses.

There was a sound of horses moving off and then silence.

All round her she heard the sounds of horses and men, an army on the march.
