The arrival of the Union Army of the Potomac on the Virginia Peninsula brought the jurisdiction of the United States into the heart of the Confederacy. As the army moved towards the Confederate capital at Richmond, it became an unwitting army of liberation.1
Blacks had been part of the war effort since near the onset of fighting, but they were used almost exclusively by one side. The Union, which claimed that ending slavery was not a war aim, disdained the help of black men. The Confederacy, an explicitly slaveholding republic, made extensive use of the labor of free and enslaved blacks for military purposes.2
When 120,000 Union soldiers landed on the Peninsula, they found their advance towards Richmond blocked by line after line of Confederate fortifications. White Southern soldiers, who often protested against the menial labor of digging trenches, were not the primary laborers behind the building of these strong forts. The principal workforce was made up of enslaved African Americans.3
Many Union soldiers began to recognize that slaves were making a significant contribution to the Confederate war effort, but that when they were free from their owners’ control, blacks were reliably opposed to the Confederacy. One of those who recognized this first was an immigrant officer.
Philippe Regis de Trobriand had immigrated to the United States when he was 25 years old. A handsome, well-educated Frenchman, he earned his living publishing a French-language newspaper in New York for his fellow Francophone expatriates. After the attack on Fort Sumter in 1861, he organized a French regiment, the 55th New York, better known as the Gardes Lafayette.4

Philippe Regis de Trobriand
During the Peninsula Campaign, de Trobriand found that the only reliable intelligence information he could get from local people came from blacks. He and other white officers came to depend on the secretive information network within the community of enslaved African Americans for reports on Confederate troop movements, the morale of enemy troops, and political conditions inside rebel territory. One escaped slave was brave enough to swim across a river for the French colonel, spy on the Confederate army, and return with word that they were evacuating trenches near the old Virginia capital at Williamsburg.5
At the start of the Peninsula Campaign, the Virginia slaves Philippe Regis de Trobriand came to see as allies were living in the Confederacy, the first republic ever founded explicitly for the preservation of slavery. As Union troops moved west from the coast, however, they brought with them the jurisdiction of the United States government: Just months earlier, Congress had authorized the freeing of slaves who were forced to work for the Confederate armies. This meant that when slaves escaped and took refuge inside the Union lines, they were immigrating to another country, one with new laws antagonistic to slavery.6
Slave owners tried to inoculate slaves against the freedom flu by telling them lies about the treatment they would receive from Unionists. “In an effort to ensure that their slaves would not assist Federal troops, masters had been telling horror stories about Northerners,” historian Glenn David Brasher says in a new study of the campaign. Slaves were told of “Yankees who bored holes in black skin, cut off limbs, harnessed slaves like horses, and drove them by the lash,” writes Brasher. The most common lie told was that Union troops would trick slaves into coming over to them and then sell them for a huge profit to slave owners in Cuba, where they would be permanently separated from their families.7
In spite of the propaganda of slave owners, blacks knew that the Union invasion was the best chance for freedom most of them would ever have. Months before Lincoln’s Emancipation Proclamation, slaves on the Virginia Peninsula had concluded that a Union victory could doom slavery. They took great risks to aid Union troops, supply information to Union officers, and perform work vital to the Union war effort.8
African American resistance to slavery was rooted in the very nature of the institution. Blacks were denied all legal rights, did not own their own labor, and did not control their relationships with their spouses and children. A child could be taken from her mother and sold away as soon as a baby was weaned. Torture was used as a common method of controlling enslaved African Americans, most often through whippings. Samuel Chilton, a freed Virginia slave, said, “Whip em? Yes I seen ‘em whipped…Dey take yo’ shirt off an beat your bare back. Dey whup you ‘till de blood come.” In Williamsburg, today a colonial tourist attraction, there was a public whipping post for the beating of blacks with a cage next to it in which slaves were placed on display after their torture.9

An escaped slave in Mississippi during the Civil War shows effects of torture by whipping.
Not all slave owners were sadists, of course, but even the slaves of “kindly” masters were prone to run to the Unionists. “Kind treatment is a good thing but it isn’t liberty,” one former slave said.10
When the first escaped slaves arrived in Union camps, officers were only legally authorized to free those who had worked for the Confederate government. All other slaves were supposed to be returned to their owners. Ordinary soldiers, many of whom were not abolitionists at the start of the war, quickly denounced the ludicrousness of pausing during a violent military campaign to conduct an inquiry into who had employed the escapee, then returning the person to an owner who was likely to be a Confederate soldier.11
Added to that was the fact that slaves often came into Union lines with awful scars and other symbols of mistreatment. Many Union soldiers had never met a black person before joining the army and had no direct experience of slavery. They were shocked by the abuse they learned about firsthand. Slaves told of being raped, seeing their young daughters sold off to lecherous owners, and being punished for resisting the breakup of their families. Soldiers began refusing to allow slave catchers into their camps to retake runaways.12
The decision by slaves to “immigrate” into the lines of the Union army, their important role in guiding Union troops, and the work they performed had a profound effect on the advance toward ending slavery. According to historian Glenn Brasher, “the ways in which African Americans participated in the campaign helped prepare Northerners to accept emancipation as a military necessity.”13
“No More Auction Block for Me” was a song sung by escaped slaves who assisted or joined the Union Army during the Civil War:

According to Brasher, here are several of the core elements showing that the Peninsula Campaign to help foster emancipation: 1) When Union forces moved west from Fort Monroe they were blocked by strong entrenchments built with slave labor; 2) Stories circulated, some based on direct evidence, that slaves were being used to man cannons and engage in other military activities; 3) Slaves provided valuable information on geography and enemy movements; 4) Slave owners that troops encountered were nearly all pro-Confederate; 5) Some Union soldiers found their racist views challenged by direct experience with blacks; 6) The violence of slavery was brought home to Unionists who were viewing it up close for the first time; 7) Black workers relieved Union soldiers of duties they would have otherwise have had to perform; 8) Escaped slaves expressed a desire to take up arms in support of the Union; 9) The ultimate defeat of the Army of the Potomac in the Peninsula Campaign signaled to Northerners that a harsher war would be necessary to defeat the South.
