Bingo! The 300 Spartans hold up the Persian army long enough for the Greek city states to get organized and eventually leads to victory.
I figured it was that war, so I just guessed the only battle I know of it. Ah well. [edit] I'm wrong. I don't know anything of that battle. The one I know about was Koniggratz where one of the armies didn't get a telegraph and so showed up late to the engagement. That really tickles me for some reason.
Did this battle take place on the water with many ironclads? If it is I don't remember the name and I don't want to take the fun out of it by googling.
20th Century, Far East. Without Increased Joy, and with the Red Castle in flames, a lone Flying Dragon battled through the afternoon, until slain.
Perhaps another hint then.... Only the second battle of its kind. 5 out of 7 of this type of ship were sunk.
Aircraft carriers in the South Pacific, U.S. v Japan. Lemme look that shit up in my history book.... Battle of the Coral Sea? No... only two carriers total were lost. Maybe Midway?
