Archibald returned to his regiment in Madras, India in January 1832. Caroline joined him 18 months later. When she saw the bad behaviour of some of the girls, she asked the Governor of Madras to help her set up a school. In 1834, Caroline founded the Female School of Industry for the Daughters of European Soldiers. The school provided a practical education for the girls. They were taught to read and write and about religion, cooking, housekeeping, and nursing. Caroline gave birth to two sons, Archibald and William, and she followed her husband around in his travels.
