of today, there is only one in this world." Like Pius X, Pius XI had been a blunt-spoken, no-nonsense pontiff. Assembling in 1939 as the outbreak of hostilities that became the Second World War was widely anticipated, the cardinals turned to a soft-spoken diplomat. Balloting Pacelli, in his role as Camerlengo, announced on 10 February that the College would wait the maximum time allowed, eighteen days from the death of the pope, to start the conclave. The time period before starting had been lengthened following the previous conclave, for which three North American cardinals had arrived too late to participate. When the 31 cardinals available discussed the question on 11 February, they amended his plan only to provide that they would start earlier if all those who planned to attend had arrived in Rome. The cardinals arrived slowly in Rome, with just 37 attending the papal funeral on 14 February and 46 at a funeral Mass on 18 February. By 20 February, starting the conclave on 28 February appeared to be a possibility, as only three non-Italians had yet to arrive: William Henry O'Connell of Boston, Sebastião da Silveira Cintra of Rio de Janeiro, and Santiago Copello of Buenos Aires. On 22 February the cardinals sitting in general congregation settled on 1 March, expecting the three to arrive at Naples on the S.S. Neptunia on that morning. The conclave was held in the Apostolic Palace. All the cardinals attended, 35 Italians and 27 from other countries. The doors closed at 6:17 pm. Pacelli won a narrow victory on the second ballot with the lowest possible two-thirds majority, 42 out of 62. He then asked for an additional ballot to confirm his election by a larger margin. To the question "Acceptasne electionem de te canonice factam in Summum Pontificem?", Pacelli replied "Accepto in crucem" (I accept it as a cross). He explained his choice of Pius by saying, "I call myself Pius; my whole life was under Popes with this name, but especially as a sign of gratitude towards Pius XI." The white smoke signifying a successful election appeared at 5:30 pm, but began to turn black. Vincenzo Santoro, the conclave secretary, then sent a note to Vatican Radio to confirm that the smoke was white and Pacelli had been elected. At 6:06 pm, the Protodeacon, Cardinal Camillo Caccia-Dominioni, made the Habemus Papam announcement in Latin from the balcony of St.
