How Many Men Would Survive?

"LOOK OUT BEHIND YOU!"
Your men turn around and see the 10 enemies behind them and they prepair for the battle they'll have.
2 of your men go for the one on the far left. The enemie gets hit by one but was able to throw his dagger at the other so now its 10 vs 19.
But before the eneime dies he's able to crush the head of the one stabbed him so its 9 vs 18.
Next 5 of your men go up against 2 of the enemies but out of now where someone that looks like the enemies sends an icy blast towards your enemies and destroys them so now its
4 vs 18 and everyone is confused but you...
