The easy way to do this scene is to get a couple of weapons, especially the explosives. Then get detected and run back to the gate you came into the village from. If you fight them from this narrow path, they can only come 2 at a time. Wait until theres a swarm of them together and nuke them with the grenade/explosives. Wii version much easier for one shot kills too, so snipe em before they get in attacking range.
It was by far one of the hardest parts of the game thus far. After I beat Zelda, Im going back and finishing this game.
