The hum of either army stilly sounds, That the fix'd sentinels almost receive The secret whispers of each other’s watch. Fire answers fire, and through their paly flames Each battle sees the other’s umber'd face: Steed threatens steed, in high and boastful neighs Piercing the night’s dull ear; and from the tents, The armourers, accomplishing the knights, With busy hammers closing rivets up, Give dreadful note of preparation.
