Post-war assignments and resignation
Grant's first post-war assignments took him and Julia to Detroit on November 17, 1848, but he was soon transferred to Madison Barracks, a desolate outpost in upstate New York, in bad need of supplies and repair. After four months, Grant was sent back to his quartermaster job in Detroit.[71] When the discovery of gold in California brought 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.[72] When orderlies protested having to attend to the sick, Grant did much of the nursing himself, earning high praise from observers.[73] In August, Grant arrived in San Francisco.
