|"Because even though his army was outnumbered, he cleverly calculated his advantages. The enemy was downwind and there was a drought. Their defenses burned to a crisp in minutes."|
|— Azula explaining how Fire Lord Sozin won the battle.|
The Battle of Han Tui was an early conflict in the Hundred Year War between the Fire Nation and the Earth Kingdom. The Fire Nation forces were commanded by Fire Lord Sozin, and although they were outnumbered, they emerged victorious due to Sozin's military advantages and tactical prowess.
The city of Han Tui was besieged by Fire Lord Sozin's army. Despite his forces being outnumbered, Sozin carefully calculated his advantages; a prolonged drought had both limited the supplies of the defenders and created ideal conditions for a wildfire, and Han Tui's position downwind of the Fire Nation Army meant that the flames would spread toward the city. With the defenses completely obliterated in minutes, Sozin's forces converged on the city and won the battle.
- The Battle of Han Tui bears resemblance to the Battle of the Red Cliffs during the Three Kingdoms period, when warlord Sun Quan scored a decisive victory against Cao Cao's fleet. He attacked using fire against the enemy, which was in the opposite direction of the wind.
