The Goblin Horde

"Halt!" cried Gandalf, who appeared suddenly, and stood alone, with arms uplifted, between the advancing dwarves and the ranks awaiting them.

"Halt!" he called in a voice like thunder, and his staff blazed forth with a flash like the lightning. "Dread has come upon you all! Alas! it has come more swiftly that I guessed. The Goblins are upon you! Bolg of the North is coming, O Dain! whose father you slew in Moria. Behold! the bats are above his army like a sea of locusts. They ride upon wolves and Wargs are in their train!" 

Amazement and confusion fell upon them all. Even as Gandalf had been speaking the darkness grew. The dwarves halted and gazed at the sky. The elves cried out with many voices. 

"Come!" called Gandalf. "There is yet time for council. Let Dain son of Nain come swiftly to us!"
