Question: What was the Hertford Town club record the year that Scott Neilson joined? Passage:Neilson was a member of Norwich City's youth teams at the age of 11, went on to Charlton Athletic and also won schoolboy honours for Wales. His senior career started at his brother Tony's club Hertford Town of the Isthmian League in 2005. He was top goalscorer for the reserves when he made his debut on 25 October in an Isthmian League Associate Members Trophy game against Clapton, before going on to play 15 games in his first season and scoring one goal. In his second season, he played 24 games upping his goal tally by another nine, before he earned a move in December 2006 to Ware a second club where his brother also played. In one game in January 2008, Neilson came off the bench to score four goals for Ware against Tilbury in a 52 victory. The goals went towards Neilson's total of 23 from 40 games for Ware in the Isthmian League First Division North, helping Ware towards the end-of-season play-offs. However, he left Ware before the end of the season to join Cambridge City in March 2008 for the rest of the club's Conference South campaign.

Question: The year that Debeaumarche was transported from Pantin to Buchenwald, which area was more populated during that time? Passage:He was arrested on 3 August 1944 at the Gare Montparnasse, and questioned harshly by the Gestapo at the Rue des Saussaies. He lost consciousness under the beatings but did not divulge any names; he was subsequently held at Fresnes Prison. Debeaumarche was one of the so-called "77,000" (named for the prisoners' numbers, between 76,000 and 78,000), Fresnes prisoners who were transported by train from Pantin to Buchenwald on 15 August 1944. He was moved to the underground factory of Mittelbau-Dora which produced V-1 flying bombs and V-2 rockets, and posing as an electrical engineer was put to work in the manufacture of the V-1. Maurice Naegele, a Kapo in the tunnel assembly section, gained the trust of Debeaumarche by relating details of the resistance movement in France. In fact Naegele had been an agent of the Gestapo, before his deportation. Naegele denounced Debeaumarche to SS-Oberscharfuhrer Sander, head of surveillance at Mittelbau-Dora. Debeaumarche was arrested with others (including Naegele) on the night of 34 November 1944. They were taken to the Niedersachswerfen SD headquarters, where Naegele attempted to beat confessions out of the other prisoners. Debeaumarche was sentenced to death on 11 November 1944, but the sentence was not carried out. Instead Debeaumarche was held in solitary confinement, accused of anti-Nazi plotting. In April 1945 he was moved to Bergen-Belsen, where he was liberated during the advance of Allied troops on 15 April 1945 and repatriated to France. On 1 May 1945 he marched down the Champs-Elysees alongside fellow Buchenwald-captive Pierre Dejussieu-Pontcarral.
