on march 12, the superior provisional government gave an order that recognized and confirmed san martin's services. the triumvirate had written to the government asking that san martin be appointed commander of the mounted grenadiers squadron, which was about to be raised. san martin set out to form a new cavalry corps that would be patterned after the swiss army's mounted grenadiers. his goal was to create a unit made up of native soldiers trained in cavalry tactics and mounted combat skills that could effectively support the argentine army. over the next several months, he built what became known as the "mounted grenadiers squadron".
