Question: How many members did No. 11 Group have during the years of the Blitz? Passage: the Second World War, the station was very active during the Battle of Britain and the Blitz in 1940–41 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.

Question: How many horses did Kinghaven Farms own when Alydeed won the Derby Trial? Passage:Alydeed was owned and raced by David Willmot's Kinghaven Farms. Racing from a base at Woodbine Racetrack in Toronto, at age two his best performances were wins in an allowance race at Gulfstream Park in Florida, where he equalled the track record for 6.5 furlongs, and a win in Woodbine's Victoria Stakes. At age three, Alydeed won five of his ten starts. Near the end of April 1992, he was sent to Churchill Downs in Louisville, Kentucky where he won the Derby Trial. Based on his strong performance, his handlers decided to run him in the second leg of the U.S. Triple Crown series, the Preakness Stakes where he ran second to Pine Bluff. Back at Woodbine Racetrack, he won the Plate Trial Stakes then ran away from the field in the final quarter of a mile to win Canada's most prestigious race, the Queen's Plate. In the second leg of the Canadian Triple Crown series, the Prince of Wales Stakes, Alydeed was sent off as the prohibitive favorite at 1/9 odds. However, on a muddy Fort Erie Racetrack, Alydeed ran second to Benburb. Alydeed then elected to skip the third jewel of the Canadian Triple Crown opting for the Grade 1 Travers Stakes at Saratoga Race Course where he finished eighth to Thunder Rumble as the 8-5 favourite.
