As the war erupted with the attack on the Republic Navy depot at Foerost, Terep seized control of Wrangler for himself when the warship's captain hesitated upon learning of the mission's parameters. For the next three years of the conflict Terep operated independently, placing his ship along contested galactic hyperlanes in order to interdict passing convoys. However, his attempts met with limited success, often forcing him to withdraw from battle. These actions culminated in a skirmish in the Upestis system against a small Republic force led by Padawan Bastila Shan and her battle meditation. In the wake of this battle Terep began attacking his crew in frustration, eventually succumbing to a mutiny led by Josef Farfax and Secar Dunnigal, two of Wranger's senior officers.
