|The Two Towers chapters|
Treebeard is the fourth chapter of the third book in The Two Towers.
The Hobbits ran as fast as they could into the forest, finally stopping for a drink of water. They came upon a sort of rock wall and climbed up natural stairs, where they meet an Ent, or Treebeard, as he called himself. Treebeard was the oldest living creature in Middle-earth, a fourteen-foot guardian of Fangorn Forest. He took the Hobbits to an Ent house and gave them drink and shelter. He knew Gandalf and asked the Hobbits for news of the outside world. When he came to know about Saruman and how he had tamed Orcs to serve him, he was angry. He decided to gather all the Ents and march to Isengard. Treebeard told the Hobbits that there weren't many Ents left because all the Entmaidens and Entwives had gone away and the Ents could not find them. Due to no new Entings being born and the Ents growing old, the population was dwindling.
The next day Treebeard took the Hobbits to a meeting of ents at Entmoot. Two dozen Ents were gathered and more came. The next day they marched to Isengard. The ents were angry at Saruman, their neighbor, who cut down their trees and burned them without reason and who also trained Orcs not to be afraid of Fangorn. Pippin looked behind and saw the whole forest moving. The trees had awakened and were marching towards Nan Curunír, the valley of Saruman.
