Question: What age was Jerry Valiant the year Roberston's final title reign ended? Passage 1:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.
 Passage 2:When the American Civil War began, Weitzel was assigned to construct defenses, including in Cincinnati and Washington, as well as for George McClellan in the Army of the Potomac in late 1861. He was then attached to the staff of Major General Benjamin F. Butler as chief engineer of the Department of the Gulf. When Union troops captured New Orleans, Weitzel became assistant military commander and acting mayor. He was promoted to brigadier general in August 1862 and two months later routed a large force of the enemy at Labadieville, Louisiana, which earned him a brevet promotion to major in the Regular Army. Weitzel commanded a brigade in the XIX Corps advancing in Major General Nathaniel P. Banks's operations in western Louisiana during April and May 1863, which led to the siege of Port Hudson. Weitzel was later brevetted lieutenant colonel in the Regular Army, "for gallant and meritorious services at the siege of Port Hudson," which fell on July 9, 1863, days after Vicksburg, Mississippi, about 120 miles upriver, the last Confederate stronghold on the great Mississippi, had fallen. Together those successful sieges and the continuing blockage of Southern ports completed the Anaconda Plan.
