Input: Consider Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Input: Consider Input: Question: How long had Kortrijk been a team when Gillenken made his debut for OH Leuven? Passage:Gillekens made his debut for OH Leuven in the 201415 Belgian Cup in the sixth round match against Kortrijk, a 1-3 loss, although that season he was part of the reserves and only fourth goalkeeper behind Logan Bailly, Yves Lenaerts and Senne Vits. Later that season he also played one match in the 201415 Belgian Second Division against Mons. Although Gillekens was promoted to third keeper for the 201516 season, he did not play a single match that season. Following the relegation from the 201516 Belgian Pro League, first goalkeeper Rudy Riou was released while second goalkeeper Yves Lenaerts had already signed for ASV Geel. As such, Gillekens was promoted to first goalkeeper for the 201617 season in the Belgian First Division B. During the winter 201718 transfer window OH Leuven signed Kawin Thamsatchanan, captain of the Thailand national football team and soon thereafter Gillekens was demoted to reserve goalkeeper. Following Thamsatchanan's injury during the 201819 season, Gillekens again became first goalkeeper for a few matches before then being surpassed by Laurent Henkinet. Towards the end of the season, Gillekens was even demoted to third goalkeeper with Thamsatchanan now taking his place on the bench and after the final match of the season it became clear that Gillekens would not be signing a new deal at OH Leuven.
