Question: How long did the war that Potter fought in as an officer in the Royal Field Artillery last? Passage:Potter was born in Bedford to Reverend Brignal Peel, a Wesleyan minister, and Elizabeth Stimson. He was educated at Bedford Modern School and for a time at Worcester College, Oxford. He first performed in E. M. Royle's The White Man at the Lyric Theatre in London before touring. In 1915 he was George Robey's understudy at the Alhambra. During the Great War Potter served as a 2nd lieutenant in the Royal Field Artillery in France. He served in the 6th Division 2nd Brigade 21st Battery, from 8 February 1917 before returning to music hall once the war was over. Potter cultivated an individual style and persona, wearing a straw boater, wide grey flannel trousers (he said he invented the Oxford bags style at the Coliseum in 1920), an 'Old Borstolian' blazer and carrying a notebook with a rolled umbrella. James Agate described him as "that sham Harrovian who bears upon his blazer the broad arrows of a blameful life".

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 5–2 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.
