"[I]n 1782, Virginia passed a bill permitting private manumissions. Over the next ten years, Virginians manumitted about 1,000 slaves, including some who had fought as substitutes for their owners. Many more, however, were returned to slavery, so many, in fact, that the legislature felt compelled to speak out against this obvious injustice. In the fall of 1783, it passed a bill condemning owners who contrary to principles of justice and to their own solemn promise," kept their substitutes in slavery. It also instructed the Attorney General of Virginia to act on behalf of slaves held in servitude despite their war-time service and grant them the freedom they had earned. It is unknown how many slaves were freed in Virginia as a reward for military service."
