In a sense. I can see how it would fit in there. The "300" movie was actually based on a comic book called "300" by Frank Miller, which was based on the actual historical battle of Thermopylae- but definitely highly dramatized with some other fictional things put in along with the actual historical details. So you can imagine how much the movie hyped up the comic book from there.
Not to mention the fantastical creatures.

Of course, an even cooler battle was the one Gideon and the Israelites fought against the Midianites. God took 300 Israelites to soundly defeat an army that was "thick as locusts", whose "camels could no more be counted than the sand on the seashore." You can read about that in Judges 6-8.
