Warsong Gulch is a 10v10 capture-the-flag style battleground that traces the conflict between the Silverwing Sentinels seeking revenge on the orcs that chopped down the Ashenvale forest during the Third War. A faction wins when they have returned three enemy flags within 25 minutes, or if they have returned the most flags (or capped last if a tie) when the timer runs out. The longer a flag carrier holds onto a flag, the more damage the player will take.

Each base has a long tunnel with several floors and platforms that can only be accessed via certain routes. A common technique is for the flag carrier to hop between floor levels while the attacking team tries to figure out which floor the FC is hidden on, or jump away from melee attackers.

For a long time, this was the only battleground available to level 10 players, making it the only battleground for twinks.
