The battle of Amthau was a small battle between a small band of rouge Jedi and a squadron of storm troopers. Ahsoka Tano was the only survivor of this short lived battle and has forever remained alone.
Video of Ahsoka and Anakin in a lightsaber fight against a Battle droid. This is a scene of season 1, I found it on youtube created oleh clonewarsexperience.
