droves of prospectors and settlers to the territory, Grant and the 4th infantry were ordered to reinforce the small garrison there. Grant was charged with bringing the soldiers and a few hundred civilians from New York City to Panama, overland to the Pacific and then north to California. Julia, eight months pregnant with Ulysses Jr., did not accompany him. While Grant was in Panama, a cholera epidemic broke out and claimed the lives of many soldiers, civilians, and children. Grant established and organized a field hospital in Panama City, and moved the worst cases to a hospital barge one mile offshore. When orderlies protested having to attend to the sick, Grant did much of the nursing himself, earning high praise from observers. In August, Grant arrived in San Francisco.

With no means of support, Grant returned to St. Louis and reunited with his family, uncertain about his future.
