For all of us who need it, some exam mojo

...[King Théoden] sat upon Snowmane, motionless, gazing upon the agony of Minas Tirith, as if stricken suddenly by anguish, or by dread. He seemed to shrink down, cowed by age. Merry himself felt as if a great weight of horror and doubt had settled on him. His heart beat slowly. Time seemed poised in uncertainty. They were too late! Too late was worse than never! Perhaps Théoden would quail, bow his old head, turn, slink away to hide in the hills.

Then suddenly Merry felt it at last, beyond doubt: a change. Wind was in his face! Light was glimmering. Far, far away, in the South the clouds could be dimly seen as remote grey shapes, rolling up, drifting: morning lay beyond them.
But at that same moment there was a flash, as if lightning had sprung from the earth beneath the City. For a searing second it stood dazzling far off in black and white, its topmost tower like a glittering needle; and then as the darkness closed again there came rolling over the fields a great boom.
At that sound the bent shape of the king sprang suddenly erect. Tall and proud he seemed again; and rising in his stirrups he cried in a loud voice, more clear that any there had ever heard a mortal man achieve before:

Arise, arise, Riders of Théoden!
Fell deeds awake: fire and slaughter!
Spear shall be shaken, shield be splintered,
A sword day, a red day, ere the sun rises!
Ride now, ride now! Ride to Gondor!

With that he seized the great horn from Guthláf his banner-bearer, and he blew such a blast upon it that it burst asunder. And straightaway all the horns in the host were lifted up in music, and the blowing of the horns of Rohan in that hour was like a storm upon the plain and a thunder in the mountains.

Ride now, ride now! Ride to Gondor!
