William Wallace: Yes, I've heard! Kills men by the hundreds. And if he were here, he'd consume the English with fireballs from his eyes, and bolts of lightning from his arse!
(the Scottish army laughs)
William Wallace:I am William Wallace! And I see a whole army of my countrymen here in defiance of tyranny! You've come to fight as free men. And free men you are... What will you do with that freedom? (beat) Will you fight?!
Scottish Army: No! No!
Old soldier: Against that?! No! We will run. And we will live.
William Wallace: Aye. Fight and you may die. Run, and you'll live... At least a while. And dying in your beds, many years from now, would you be willing to trade ALL the days, from this day to that, for one chance, JUST ONE CHANCE, to come back here, and tell our enemies... that they make take our lives... BUT THEY'LL NEVER TAKE... OUR FREEDOM!!!!
(the Scottish army cheers)
William Wallace: ALBA GU BRATH!!! note SCOTLAND FOREVER!!!
The scene where the assembled English army gets mooned by THE ENTIRE NATION OF SCOTLAND.
To round up the Battle of Stirling. Wallace is charged by Hugh Cressingham on horseback. Does William try and avoid the armoured knight bearing down on him? Not a chance. He takes his blood-soaked claymore in both hands... And hews the Earl of Surrey's mount out from under him while it's bearing down on him at full tilt. Followed by taking his head clean off with a second back swing.
Wallace: "Bastard!!! COME ON!!!! ARRRRGGGGHHHH!!!!!"
The final scene, when Robert the Bruce forgoes a losers peace to lead his army against the English at Bannockburn.
"You have bled with Wallace. Now bleed with me."
Made all the more poignant by the tiny shift in Hamish's expression; a narrowing of the eyes, a shift of the jaw, telling you that the mood has, in that one line, gone from bitter resignation to undisputed CMOA.
And as he does so, he hurls Wallace's sword across the field, before they charge towards the English.
Especially poignant if you're familiar with the song the line references, Scottish patriotic song Scots Wha Hae'
Scots wha hae with Wallace bled
Scots wham Bruce has aften led
When Wallace is being executed, he is offered the chance to cry "mercy" and have the torture stop. When he finally speaks, having remained silent throughout, he only yells "FREEEEEDOOOOOOOOM."
It had a widespread effect to everyone that heard it, including shocking Longshanks enough to induce him a heart attack.
Later, Wallace personally getting back at the nobles who betrayed him.
Queen Isabella gets a couple. First, when she goes to see Wallace and the guards give her a hard time. "The King will be dead in a month and his son is a weakling. Who do you think will rule this country?" And the next scene, when she whispers in Longshanks' ear.
