He made his debut for Carlisle as a substitute in Carlisle's 3–0 win away at Canvey Island he only made one more appearance for the season again as a sub in a loss against Forest Green Rovers. At the end of the season Carlisle were promoted to League Two, in the 2005–06 season he made many more appearances for Carlisle although most of them came after being brought into the game as a sub. He also scored his first professional goal in Carlisle's 5–0 win against Rushden & Diamonds he also scored a second goal in this game, these were 2 of the 6 goals he scored in his 30 league appearances this season that made him a key part of the promotion winning team. After helping Carlisle to gain their second successive promotion up to League One. During Carlisle's first season in league one Hackney was only able to make 18 appearances this was due to him picking up a serious injury to his knee cartilage in December, however in these 18 games he did manage to score two goals. Hackney managed to recover from his knee injury in time for the 2007–08 season which enabled him to make himself a key part of the team which led to him making 45 league appearances for the club scoring eight times including a vital goal to help Carlisle end Leeds United's undefeated start to the season and help them defeat Leeds 3–1. During the first half of the 2008–09 season he made 22 appearances for Carlisle but only managed to score one goal against Crewe Alexandra, however towards the middle of the season his form dropped slightly and Jeff Smith took his place in the starting line up. Colchester United made two enquires which were both rejected after one reportedly being £25,000 being called 'a mickey take', then Colchester came back with an improved 'six-figure' offer which Carlisle accepted on 26 January. During his time at Carlisle, Hackney made over 100 appearances for the club, helped them gain successive promotions and became a huge favourite with the fans.

Input: Consider Input: Question: What were the combined ages of Joseph Urban and Benjamin Wistar Morris the year that they were both hired to come up with blueprints for the house? Passage:The construction of Rockefeller Center occurred between 1932 and 1940 on land that John D. Rockefeller Jr. leased from Columbia University. The Rockefeller Center site was originally supposed to be occupied by a new opera house for the Metropolitan Opera. By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house. However, the new building was too expensive for the opera to fund by itself, and it needed an endowment, and the project ultimately gained the support of John D. Rockefeller Jr. The planned opera house was canceled in December 1929 due to various issues, with the new opera house eventually being built at Lincoln Center, opening in 1966.

Input: Consider Input: Question: Which city had a greater population the year Gordon led his regiment to the Battle of Marks' Mills, Little Rock or Camden? Passage:In March and April 1864, Shelby's men harassed and skirmished with the Union Army force under the command of Major General Frederick Steele during his Camden Expedition, part of the Red River Campaign. Gordon led more than one charge against the Union forces during Steele's march from Little Rock to Camden, Arkansas. On April 25, 1864, Gordon led his regiment at the Battle of Marks' Mills where they captured two Union artillery pieces from the detachment of Union Lieutenant Colonel Francis M. Drake when Shelby's force attacked the Union left wing of the detachment which had been sent from Camden toward Pine Bluff, Arkansas to obtained supplies for Steele's force which was increasingly besieged by gathering Confederate forces at Camden. The Confederates outnumbered the Union force at Marks' Mills by more than 2 to 1 and overwhelmed it, taking about 1,300 prisoners and about 240 wagons. The overall commander of the Confederate cavalry force at Marks' Mills, Brigadier General James Fagan, led the Confederates, including Shelby's command, toward Pine Bluff in an effort to capture the Union supply depot. The Confederates did not make it to Pine Bluff due to flooding. They also did not return fast enough to cut off Steele's return march to Little Rock or to participate in the Battle of Jenkins' Ferry, the one big engagement during the retreat before the Union troops escaped across the swollen Saline River.
