Their dim hope of catching their friends grows even fainter.
The Uruk-hai.
Pippin and Merry, in the custody of the Orcs, lie captive awaiting their fates. By listening to the conversation, Pippin learns that there are two groups of Orcs. In the course of taking the captives, the two groups have fought one another. Pippin gets hold of a knife and cuts his bonds, tying a loose knot around his wrists. .
The prisoners are picked up and after another short journey, the Orc's messenger tells them that a single horseman was seen nearby. This time Merry and Pippin are made to walk instead of being carried. Pippin manages to break free, but is caught. Fortunately before he is caught, he manages to lose his cloak pin, a broach. He loses consciousness and only regains it when the Orcs stop. Eomer and his men attack the Orcs and Merry and Pippin manage to escape into Fangorn.
Treebeard.
The Hobbits run as fast as they can into the forest, finally stopping for a drink of water. They come upon a sort of rock wall and climb up natural stairs, where they meet an ent, or Treebeard, as he calls himself. Treebeard is the oldest living creature in Middle-earth, a fourteen-foot guardian of Fangorn forest. He takes the Hobbits to an ent house and gives them drink and shelter. He knows Gandalf and asks the Hobbits for news of the outside world. When he comes to know about Saruman and how he has tamed Orcs to serve him, he is angry. He decides to gather all the ents and march to Isengard. Treebeard tells the Hobbits that there aren't many ents left because all the entmaidens and entwines have gone away and the ents cannot find them. Due to no new entings being born and the ents growing old, the population is dwindling. .
The next day Treebeard takes the Hobbits to a meeting of ents at entmoot. Two dozen ents are gathered and more come. The next day they march to Isengard. The ents are angry with Saruman, their neighbor, who cuts down their trees and burns them without reason and who also trains Orcs not to be afraid of Fangorn.
