 From Cartagena, the scene of his first labours, Bertrand was sent to Panama, where in a comparatively short time he converted some 6,000 people.His next mission was at Tubará, situated near the seacoast and midway between the city of Cartagena and the Magdalena River.The success of his efforts at this place is witnessed by the entries of the baptismal registers, in Bertrand's own handwriting, which show that all the inhabitants of the place were received into the Church.
