The Seventh Battle of Ruusan was the final major engagement of the conflict known as the New Sith Wars. There were actually seven prior battles on the world during the last days of the war, but the pivotal and last battle is the one most remembered, due to the use of the thought bomb, it is usually referred to just as the Battle of Ruusan. This was also the event that would lead to the Ruusan Reformation of the Galactic Republic.
