Among the 50,000 pilgrims present at the beatification Mass today in the port of Dubrovnik was Roger Cotrina Alvarado. He was the lieutenant of the submarine Pacocha, which on Aug. 26, 1988, crashed into a Japanese fishing-vessel near the Peruvian port of Callao. When the submarine began to sink, the then young officer commended himself to the intercession of Sister Maria of Jesus Crucified Petkovic, founder of the Franciscan Congregation of the Daughters of Mercy. At that moment, Cotrina Alvarado was able to close an inside door with the strength of his arms, despite the pressure of the water that was flooding the submarine. The maneuver was considered "humanly impossible" by two commissions, one military and the other Vatican. The miracle became the door that opened the way for the Croatian's beatification. Nineteen other officers trapped in the submarine were saved; six crew members died in the accident.
