Hard by a castle 'gainst whose square, grey towers,
Machicolated, mossed, in forest bowers,
Full many a siege had beat and onset rushed:
A forest fortress, old and deep-imbushed
In wild and woody hills. And then one wound
A hoarse slug-horn, and at the savage sound
The drawbridge rumbled moatward, clanking, and
Into a paved court rode that little band.
