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.

Example Input: Question: How long did the battle that Seitz led the regiment in during the opening phase in November of 1944 last? Passage:From November 26, 1943 to April 9, 1945, Seitz commanded the 26th Infantry Regiment (organized for the 1944-1945 campaign in France, Belgium and Germany as Regimental Combat Team 26 or Combat Team (CT) 26). CT 26 was a unit of the 1st Infantry Division (United States). Seitz commanded the combat team at Omaha Beach during the Normandy landings on D-Day, in the breakout from Normandy and at the approach to close the gap in the Falaise Pocket. The First United States Army, including Seitz's regimental combat team, hotly pursued the fleeing German Army divisions across France to the border of Germany by September 7, 1944. On October 11, 1944, after heavy fighting during the Battle of Aachen, Seitz led two of the three battalions of the regiment into heavily defended Aachen, Germany. They seized the first German city to fall to the Allies of World War II after 8 days of urban combat. In November 1944, Seitz led the regiment during the opening phase of the Battle of Hürtgen Forest. Starting only 10 days after the regiment was withdrawn from this bloody and costly battle, Seitz directed CT 26's heroic, successful stand at the Battle of Bütgenbach, an important part of the Battle of the Bulge that followed the Battle of Elsenborn Ridge. With many replacement soldiers due to losses in the Hürtgen Forest, and with skillful artillery support, Seitz and the outnumbered 26th Infantry Regiment team prevented the Nazi 12th SS Panzer Division Hitlerjugend, 3rd Parachute Division (Germany) and the 12th Volksgrenadier Division, which were supported by dozens of tanks, from breaking the Allied line at Bütgenbach.
