Tully was part of Judge Ramsey's expedition to destroy President Thomas Voss Government at Freedom Base in the Ozark National Forest, Arkansas. Ramsey and the regulators also aimed to seize 5,000 doses of the Hale Vaccine that were produced there. The operation was succesful and the Regulators began their 290 miles trip home to Tunnel-Through.
Whilst travelling on a shallow river in the Badlands, the Regulators were swarmed by hundreds of Leapers. Tully was mortally wounded by the creatures and knowing that he was dying asked to see the Judge. The Judge knew Tully and agreed to see him, possibly indicated that Tully held a high rank in the Regulators; during the converstation Tully asked the Judge to give his wife his pay and gear, Ramsey accepted and promised to remove all debt the Tullys had raised in the company store. Feeling satisfied, Tully then asked Judge Ramsey to execute him rather than leaving him to die from his wounds. The Judge agreed again and executed Tully with a British .455 Webley Break-Top revolver.
