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 armorers, accomplishing the knights, With busy hammers closing rivets up, Give dreadful note of preparation.
