Question: When was the only team Porto lost against in its group in the 2003–04 UEFA Champions League founded? Passage 1:He was promoted to lieutenant on 23 January 1962, captain on 23 July 1966, and major on 31 December 1972, At this time he was brigade major at HQ 3rd Infantry Brigade in Northern Ireland. As such he was responsible for the efforts to find Captain Robert Nairac who had been abducted by the Provisional IRA. Nairac and Jones had become friends and would sometimes go to the Jones household for supper. After a four-day search, the Garda Síochána confirmed that Nairac had been shot and killed in the Republic of Ireland after being smuggled over the border. On 13 December 1977 he was appointed a Member of the Order of the British Empire (MBE) for his services in Northern Ireland that year. On 30 June 1979 he was promoted lieutenant colonel, and on 1 December 1979, he was transferred to the Parachute Regiment. In the 1981 New Year Honours he was appointed an Officer of the Order of the British Empire (OBE).
 Passage 2:The 2003–04 season began with another 1–0 win over União de Leiria, which gave the club its 13th Supertaça. Weeks later, Porto failed to repeat this result in the 2003 UEFA Super Cup, losing 1–0 to Milan. The departure of striker Hélder Postiga was compensated by the signing of South Africa's Benni McCarthy, whose 20 league goals helped Porto in its league title defence and crowned him the competition's top scorer. Mourinho entered the 2003–04 UEFA Champions League with confidence to his team. Porto finished second in its group, losing only once to Real Madrid, and advanced to a round-of-16 meeting with Manchester United. Porto scored on the 90th minute of the second leg at Old Trafford to draw 1–1 and advance to the quarter-finals with a 3–2 aggregate win. The team then overcame Lyon and Deportivo La Coruña and reached the Champions League final, where it defeated Monaco 3–0 to lift the club's second European Champion Clubs' Cup. A 2–1 loss to Benfica in the Taça de Portugal final, held 10 days before, prevented another treble-winning season.
