Battle of Tibrin / Legends The Battle of Tibrin of 22 BBY was a failed Galactic Republic attempt to oust the Confederacy of Independent Systems ' military presence from the planet Tibrin during the Clone Wars . The native Ishi Tib populace had previously welcomed the arrival of Separatist leader Count Dooku and his cadre of Dark Acolyte s , who executed Suribran Tu — the planet ' s unpopular , pro - Republic premier — and overthrew his totalitarian regime . Consequently , the Ishi Tib aided the Confederacy when Jedi and clone troopers from the Grand Army of the Republic came to retake Tibrin . The result was a catastrophic Republic defeat , with Tibrin retaining its Separatist ties . Many of the clone soldiers who survived the battle , including Commander Gree of the 41st Elite Corps , adopted a hairstyle called the double stripe to honor their fallen comrades . Prelude . Since the outbreak of the Clone Wars in the year 22 BBY , the native Ishi Tib inhabitants of the Mid Rim planet Tibrin clamored to join the Confederacy of Independent Systems . Yet the planet ' s dictatorial premier , Suribran Tu , retained the support of the Galactic Republic , even though his administration oppressed the will of the people and was marred by corrupt practices , such as strong - arm tactics and political assassinations . When Separatist leader Count Dooku came to negotiate for the rights to use Tibrin as a base , he was unimpressed with Tu ' s willingness to become a Separatist - loyal planetary ruler simply as a means of preserving his own position and power . Seeing no benefit to further deliberations , Dooku beheaded Tu with his lightsaber and had the ex - dictator ' s head publicly displayed for the citizenry to see . Dooku also installed one of his Dark Acolyte s , Sora Bulq , as Tibrin ' s provisional governor , with orders to purge Tu ' s inner circle — everyone from military and political officers to his family . The Ishi Tib population , grateful to be free of Tu and the Republic , extolled Dooku as a liberator and eagerly joined the Confederacy , inciting a revolution on their world . The battle . Unwilling to let the Confederacy ' s influence on Tibrin go unchallenged , the Republic sent clone trooper forces from the Grand Army of the Republic , under the command of Jedi officers , to uproot Dooku ' s military presence on Tibrin . Commander Gree of the 41st Elite Corps , Marshal Commander Cody of the 212th Attack Battalion , and Captain Rex of the 501st Legion were among the Grand Army ' s troop leadership . However , the Ishi Tib resisted the Republic ' s attempts to meddle in their homeworld ' s affairs . The campaign ended in a crushing defeat for the Republic forces , with many clone soldiers perishing in the battle . Aftermath . The Battle of Tibrin , as the grisly campaign came to be known , resulted in the Ishi Tib preserving their loyalty to the Confederacy . Though they continued to send a representative to the Republic Senate in the form of Senator Gume Saam , he held clandestine connections to the Separatists and the Techno Union , becoming involved in a war - profiteering plot to thwart a peace initiative between the Republic and the Separatist Parliament . To honor the comrades they lost at Tibrin , Commander Gree and many other clone survivors of the battle adopted a red - colored buzz cut that became known as the double stripe . Behind the scenes .
