Question: What years did the commander in chief of the armed forces that Crespo serve under rule? Passage 1:In 1970, 22-year-old Crespo had dropped out of IST and was eventually drafted into military service in the Portuguese Colonial War. He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaúlza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation. While serving in the army, Crespo also entered the newly created School of Medicine of the University of Lourenço Marques where he would complete a number of academic disciplines but did not graduate. He also married Helen de Souza from Johannesburg, a South African woman with Portuguese ancestry who worked in genetics. After the Carnation Revolution left-leaning military coup at Lisbon in April 1974, fresh out of the troop, Crespo fled Mozambique for South Africa.
 Passage 2:On his first race of 2002, Boreal made his first appearance outside Germany when he contested the Dubai Sheema Classic at Nad Al Sheba Racecourse on 23 March. Ridden by Kieren Fallon, he stayed on strongly in the straight and finished third behind Nayef and the New Zealand gelding Hades with the other beaten horses including Marienbard and Tobougg. On 7 June, the colt was sent to England and attempted to become the first German-trained horse to win the Coronation Cup over one and a half miles at Epsom Racecourse. Racing on soft ground, he started 4/1 third favourite behind Kutub (Preis von Europa, Gran Premio del Jockey Club, Singapore Gold Cup), and Storming Home. The other three runners were Marienbard, Zindabad (Yorkshire Cup), and Pawn Broker (Arc Trial). Fallon positioned the German challenger just behind the leader Zindabad before taking the lead entering the straight and tracking across to the stands-side (outside) rail. Boreal went clear of his rivals in the last quarter mile and won by three and a half lengths from Storming Home with Zindabad six lengths back in third. After training the first German winner at Group One level in Britain since Star Appeal took the 1975 Eclipse Stakes, Schiergen said, "He travels smoothly on good ground but is more at home on soft. It's a special thrill to have a winner in Britain, and extra-special when it's a Group 1 at the home of the Derby."
 Passage 3:Prior to the launching of her next output, Tobias was cast on the screen in Kruté radosti (2002) and Zostane to medzi nami (2003), respectively. Musically, she first returned on various artist compilation Tak to chodí (2003), produced by Michal Horáček. Following that, her second BMG album was issued on December 8, 2003. As with her previous release, neither Punto Fijo achieved a presence in the official albums charts. Nevertheless, its ballad repertoire with jazz, folk and ska-inspired music brought Tobias favorable feedback from music critics. In 2006, she appeared as guest on Horáček's follow-up project, Strážce plamene. The multi-platinum compilation and Anděl Awards-nominee for the Album of the Year, included a solo track designed for herself by Petr Hapka — "Na hotelu v Olomouci". The composition wouldn't crack the Rádio Top 100 Oficiální, but her vocal performance has been generally viewed by many as the best of the set, and singer gradually started to gain her own fan base in the Czech Republic.
