After the major Republic victory at Sasquatch, and simultaneously winning the Battle Of Commenor, the CIS was forced into retreating into the Outer Rim systems. Almost every Republic ship then engaged in what became known as the Outer Rim Sieges, bombarding every CIS planet known in order to hopefully get Count Dooku and General Grievous to surrender.
Boz Pity became the staging ground for these Sieges.
Even after Anakin Skywalker and Obi-Wan Kenobi rescued Palpatine from Grievous, and killed Dooku in the course of doind so, the Sieges continued. Immediately after Grievous' death, Order 66 was issued and all Clonetroopers turned on their Jedi Generals. This effectively ended not only the Sieges but the Clone Wars as well.
