In the meantime Niort had been attacked. De Mouy defended the place stoutly, and sallied out and repulsed the enemy. His bravery, however, was fatal to him. A Catholic named Maurevel, tempted by the fifty thousand crowns that had been offered for the assassination of Coligny, had entered the Protestant camp, pretending that he had been badly treated by the Guises. No opportunity for carrying out his design against the Admiral presented itself, and he remained at Niort with De Mouy; who, believing his protestations of attachment for the cause, had treated him with great friendship. As the Huguenots were returning after their successful sortie, he was riding in the rear with De Mouy and, seizing his opportunity, he drew a pistol and shot the Huguenot leader, mortally wounding him. He then galloped off and rejoined the Catholics; and was rewarded, for the treacherous murder, by receiving from the king the order of Saint Michael, and a money reward from the city of Paris. The garrison of Niort, disheartened at the death of their leader, surrendered shortly after. Several other strong places fell, and all the conquests the Protestants had made were wrested from their hands. The battle of Moncontour was fought on October 3rd. On the 14th the southern troops marched away, and four days later Coligny, with the remains of the army, started from Saintes. He had with him but six thousand men, of whom three thousand were cavalry. His plan was an extremely bold one. In the first place, he wished to obtain money to pay the German horsemen, by the capture of some of the rich Catholic cities in Guyenne; to form a junction with the army of Montgomery; then to march across to the Rhone, and there to meet the forces of the south, which would by that time be ready to take the field again; then to march north to Lorraine, there to gather in the Germans whom William of Orange would have collected to meet him; and then to march upon Paris, and to end the war by giving battle under its walls. The Queen of Navarre was to remain in La Rochelle, which city was placed under the command of La Rochefoucault; and the two young princes were to accompany the army, where they were to have small commands. They would thus become inured to the hardships of war, and would win the affection of the soldiers.
