Grant was captured by French forces on 16 April 1812. As he was in uniform, he was treated as an officer and gentleman by his captors, who offered him parole, which Grant accepted. His servant Leon, a local guide, was not so fortunate, and was shot. Grant was invited to dine with Marshal Auguste de Marmont, who hoped to find out more about Wellington, and who was angered by Grant's reticence. Marmont had good reason to remain suspicious of Grant, as the latter managed to send and receive secret messages while in captivity.
