The Dauntless, a Venator-class Star Destroyer, saw its construction finalized at a shipyard situated on Allanteen Six amidst the backdrop of the Clone Wars.
Its construction concluded in 22 BBY, coinciding with the completion of fellow _Venator_s, the Resolute and Pioneer. These three vessels were then grouped together to form a cohesive battle group, with their inaugural assignment placing them under the leadership of Jedi General Anakin Skywalker.
The Dauntless, in conjunction with its sister ships, received orders to proceed to Bothawui with the mission of defending it against the forces of General Grievous. During their journey to Bothawui, the fleet engaged in several smaller engagements with Grievous's forces, successfully arriving at their destination before Grievous himself. It played a role in the Battle of Bothawui, which commenced when Grievous's fleet finally made its presence known.
