The wicked shall be turned into hell, and all the nations that forget God.
The title refers to the tune itself, not some historical victory, the disputes over which battle David celebrates here are pointless. Yes, he gives thanks for God's power, but read the whole psalm as prayer: he recalls former deliverances to lift his heart toward confidence that God will do the same against these new enemies rising before him.

Commenting on Psalm 9:1-20
The justice which has punished the wicked, and preserved the righteous, remains the same, and therefore in days to come, retribution will surely be meted out. How solemn is the seventeenth verse, especially in its warning to forgetters of God.
Those who truly praise God desire that others praise Him too and labor to bring them to it. Sing praises to the Lord who dwells in Zion, in the assemblies of His people, there He meets them with His promises and expects their praises in return. Tell the nations what He has done; let them know the justice of God against those who shed innocent blood.
