Gríma (voiceover): "Helm's Deep has but one weakness. It's outer wall is solid rock for except for a small culvert in space, which is little more than a drain."

[Saruman pours explosives into a metallic ball.]

Gríma: "How? How can fire undo stone? What kind of device can break down a wall?"

[Gríma moves a candle close to the ball, but it stopped by Saruman.]

Saruman: "If the wall is breached, Helm's Deep will fall."

Gríma: "Even if it is breached, it would take a number beyond reckoning — thousands — to storm the keep."

Saruman: "Tens of thousands."

Gríma: "But my lord there is no such force."

[They walk to the balcony of the tower Orthanc and Gríma looks in awe at the sheer number of Uruk-hai warriors. A horn sounds and the army cheers.]

Saruman: "A new power is rising. Its victory is at hand."

[The warriors cheer.]

Saruman: "This night, the land will be stained with the blood of Rohan! March to Helm's Deep! Leave none alive!"

Saruman: "To war!"

Saruman: "There will be no dawn for Men."

[Merry and Pippin and Treebeard are moving past Isengard.]

Pippin: "Look! There's smoke to the south!"

Treebeard: "There is always smoke rising up from Isengard these days."

Merry: "Isengard?"

Treebeard: "There was a time, when Saruman would walk in my woods, but now, he has a mind of metal and wheels."

[The hobbits climb higher to get a view of Isengard.]

Treebeard: "He no longer cares for growing things."

[The hobbits spot the Uruk army.]

Pippin: "What is it?"

Merry: "It's Saruman's army! The war has started."
