How To Foil Your Enemies And Win Battles

I'm on a Tolkien rampage right now, so I put on ROTK in my laptop while I browse Pinterest looking at Stuff. The movie is minimized, so I'm only getting the audio. When the battle part came, this is what I heard: 

NARGH-BAGH-♪-PSHHH-HEEE-EHHHH-♪-BAUGH-BRGHSHHHH-BAAAH-EEEEEE-♪-BAGHHH-PSHHHHH-♪-EHHHH-GAAAAAH-BRGHSH-♪-BRGHSH-PAUGH-GAHH-♪-RETREAT!!!!!!

At one point I thought I heard somebody saying "Victory!!!" But it was the battle at Osgiliath, so that wasn't right. But it got me thinking, what would happen if you were having a battle-not you personally, just somebody, not anybody in particular-and your soldiers were getting beaten to banana mush, and then out of the blue, you shouted "Victory!! We have victory!!" for no reason? 

This is what I think would happen:

Random Soldier: Victory!! We have victory!!

Badguy 1: DIE! Wait, what??

Badguy 2: He said they have victory. 

Badguy 1: Hang on, we were completely dominating them a minute ago! Are we losing now?

Badguy 2: I dunno, let me check. Hey, Chief Badguy, are we winning or losing right now?

Chief Badguy: We're winning, doofus.

Badguy 1: That's what I thought, but that bloke over there said they have victory.

Chief Badguy: What?? Lemme see about that. 

[walks over to Random Soldier]

Chief Badguy: Hey, bub, we're winning. You're losing. You can't say "victory" if you're losing.

Random Soldier: Victory!!!!

Chief Badguy: What the hell, man? 

Random Soldier: VICTORY!!!!! [kills Chief Badguy]

Badguy 2: Hey, he just killed our leader! We are leaderless! We have no-one to lead us! 

Badguy 1: Nooooooo!

Badguy 2: We're going to die!

Badguy 1: Retreat!

Badguy 2: Run for your lives!

Badguys: Aaaaaaaaaaaugh!!!! 

The Badguys run screaming, and we celebrate. Everybody's happy and there's jam for tea.
