In May 1861, three enslaved men who were determined not to be separated from their families ran to Fort Monroe, Virginia. Their flight led to the phenomenon of Civil War contraband camps. Contraband camps were refugee camps to which between four hundred thousand and five hundred thousand enslaved men, women, and children in the Union-occupied portions of the Confederacy fled to escape their owners by getting themselves to the Union Army. Army personnel had not envisioned overseeing a massive network of refugee camps. Responding to the interplay between the actions of the former slaves who fled to the camps, Republican legislation and policy, military orders, and real conditions on the ground, the army improvised. In the contraband camps, former slaves endured overcrowding, food and clothing shortages, poor sanitary conditions, and constant danger. They also gained the protection of the Union Army and access to the power of the US government as new, though unsteady, allies in the pursuit of their key interests, including education, employment, and the reconstitution of family, kin, and social life. The camps brought together actors who had previously had little to no contact with each other, exposed everyone involved to massive structural forces that were much larger than the human ability to control them, and led to unexpected outcomes. They produced a refugee crisis on US soil, affected the course and outcome of the Civil War, influenced the progress of wartime emancipation, and altered the relationship between the individual and the national government. Contraband camps were simultaneously humanitarian crises and incubators for a new relationship between African Americans and the US government.
The patterns of urban slavery in North American and pre-Civil War US cities reveal the ways in which individual men and women, as well as businesses, institutions, and governmental bodies employed slave labor and readily adapted the system of slavery to their economic needs and desires. Colonial cities east and west of the Mississippi River founded initially as military forts, trading posts, and maritime ports, relied on African and Native American slave labor from their beginnings. The importance of slave labor increased in Anglo-American East Coast urban settings in the 18th century as the number of enslaved Africans increased in these colonies, particularly in response to the growth of the tobacco, wheat, and rice industries in the southern colonies. The focus on African slavery led most Anglo-American colonies to outlaw the enslavement of Native Americans, and urban slavery on the East Coast became associated almost solely with people of African descent. In addition, these cities became central nodes in the circum-Atlantic transportation and sale of enslaved people, slave-produced goods, and provisions for slave colonies whose economies centered on plantation goods. West of the Mississippi, urban enslavement of Native Americans, Mexicans, and even a few Europeans continued through the 19th century. As the thirteen British colonies transitioned to the United States during and after the Revolutionary War, three different directions emerged regarding the status of slavery, which would affect the status of slavery and people of African descent in cities. The gradual emancipation of enslaved people in states north of Delaware led to the creation of the so-called free states, with large numbers of free blacks moving into cities to take full advantage of freedom and the possibility of creating family and community. Although antebellum northern cities were located within areas where legalized slavery ended, these cities retained economic and political ties to southern slavery. At the same time, the radical antislavery movement developed in Philadelphia, Boston, and New York. Thus, Northern cities were the site of political conflicts between pro- and antislavery forces. In the Chesapeake, as the tobacco economy declined, slave owners manumitted enslaved blacks for whom they did not have enough work, creating large groups of free blacks in cities. But these states began to participate heavily in the domestic slave trade, with important businesses located in cities. And in the Deep South, the recommitment to slavery following the Louisiana Purchase and the emergence of the cotton economy led to the creation of a string of wealthy port cities critical to the transportation of slaves and goods. These cities were situated in local economic geographies that connected rural plantations to urban settings and in national and international economies of exchange of raw and finished goods that fueled industries throughout the Atlantic world. The vast majority of enslaved people employed in the antebellum South worked on rural farms, but slave labor was a key part of the labor force in southern cities. Only after the Civil War did slavery and cities become separate in the minds of Americans, as postwar whites north and south created a mythical South in which romanticized antebellum cotton plantations became the primary symbol of American slavery, regardless of the long history of slavery that preceded their existence.
