A battle does not a war make.
The Persia War lasted 50 years 499-449 BCE. It comprised many battles over the 50 years. Some names are: Lade, Marathon, Salamis, Plataia, Mykale, Eurymedon, Cyprus.
I call it the First Persian War, but something tells me that Marathon may be the answer you seek. There was fighting elsewhere, but the battle on the Plain of Marathon in 490 BC was the only significant battle of the First Persian War, whereas the Second Persian War had three significant battles (Thermopylae, Salamis, Plataea). Ergo, Marathon and the First Persian War may be synonymous in some applications.
We call it today the Persian War.
Thermopylai was a battle in the Persian War.
Plataea of the last battle in the Persian war.
It was called the Persian War.
First define the Second Persian War. The Persian War ran 499-449 BCE - it had several phases - Ionian Revolt, Persian punitive expedition against Eretria and Athens, Persian invasion of mainland Greece, Greek counter-offensive. Which among this are supposed to be 'First Persian War', Second Persian War' and 'Third Persian War' ?
The first major battle of the American Civil War was the First Battle of Bull Run or the First Battle of Manasas (they are the same battle but with a different name)
Greece. There were two Persian Wars. The First Persian War in 490 BC had only one major battle (Marathon). The Second Persian War in 480-479 BC had three major battles (Thermopylae, Salamis, Plataea). Salamis was a sea battle. The sites can be found on a map of ancient Greece, and possibly even on a map of modern Greece.
