Read the full text of Henry VI Part 3 Act 2 Scene 5 with a side-by-side translation HERE.
On a hill, Henry watches the battle and wonders which side is winning. Then he goes all philosopher on us and thinks about the life of a king.
Henry's life is full of sadness. It would have been much, much better if he were a simple shepherd. If he were a shepherd, he wouldn't have the deep worries that he has as king.
As Henry's talking, he notices a soldier carrying a dead soldier. The soldier searches the dead man for gold coins or anything valuable that he can pawn off.
Then the live soldier removes the dead soldier's helmet. Oh, no—"[I]t is my father's face," he proclaims. The soldier has gone and killed his own father in the battle. He weeps.
Henry watches and thinks about how these civil wars are really bloody.
Just then, another soldier enters and does the same thing as the first—searches for loot on a dead guy's body. Then he realizes he's killed his own son. How will he tell his wife the news? How will he go on living?
Henry says to himself that it's all the nobles' fault. They're fighting over a crown and riches when regular folk are losing their sons and fathers. The soldiers leave, and Henry feels super depressed.
Things go from bad to worse when first Prince Edward and then Margaret enter and tell Henry to run. Warwick is winning, and they've got to get out of there.
