residency rights in what seemed an echo of the demands made on China by other western powers. Native Korean Christians, with connections at court, saw in this an opportunity to advance their cause and suggested an alliance between France and Korea to repel the Russian advances, suggesting further that this alliance could be negotiated through Bishop Berneux. The Heungseon Daewongun seemed open to this idea, though it is uncertain whether this was ruse to bring the head of the Korean Catholic Church out into the open. Berneux was summoned to the capital, but upon his arrival in February 1866, he was seized and executed. A roundup then began of the other French Catholic priests and native converts. As a result of the Korean dragnet all but three of the French missionaries were captured and executed: among them were Bishop Siméon Berneux, Bishop Antoine Daveluy, Father Just de Bretenières, Father Louis Beaulieu, Father Pierre Henri Dorié, Father Pierre Aumaître, Father Luc Martin Huin, all of them members of the Paris Foreign Missions Society and canonized by Pope John Paul II on 6 May 1984. An untold number of Korean Catholics also met their end (estimations run around 10,000), many being executed a place called Jeoldu-san in Seoul on the banks of the Han River. In late June 1866 one of the three surviving French missionaries, Father Felix-Claire Ridel, managed to escape via a fishing vessel and make his way to Tianjin, China in early July 1866. Fortuitously in Tianjin at the time of Ridel's arrival was the commander of the French Far Eastern Squadron, Rear Admiral Pierre-Gustave Roze. Hearing of the massacre and the affront to French national honor, Roze determined to launch a punitive expedition, the French Campaign against Korea, 1866. Ten martyrs of the M.E.P. were canonized by John-Paul II, 6 May 1984, as part of 103 canonized martyrs of Korea, including André Kim Tegong, the first Korean priest, and 92 Korean laics: Bishop Laurent Imbert (21 September 1839) Pierre Maubant (21 September 1839) Jacques Chastan (21 September 1839) Bishop Siméon Berneux (8 March 1866) Just de Bretenières (8 March 1866) Louis Beaulieu (8 March 1866) Pierre-Henri Dorie (8 March 1866) Bishop Antoine Daveluy (30 March 1866) Pierre Aumaître (30 March 1866) Martin-Luc Huin (30 March 1866) China Father Auguste Chapdelaine, who was preaching illegally in China, was imprisoned, tortured and killed by Chinese authorities in 1856.
