Prisoners of war in the American Revolutionary War

During the American Revolutionary War (1775–83) the management and treatment of prisoners of war (POW) was very different from the standards of modern warfare. Modern standards, as outlined in the Geneva Conventions, expect captives to be held and cared for by their captors. One primary difference in the eighteenth century was that care and supplies for captives were expected to be provided by their own army, their government, or private resources.

However, it was not until seven years into the conflict and only one year before the Treaty of Paris (1783) officially ended the war, and primarily as a consequence of the Battle of Yorktown in 1781 resulting in the second British army of the war being captured, that American combatants were finally recognized as POWs by the Parliament of Great Britain in 1782.

Background
Throughout the war, there were exchanges of prisoners. These were made in the field or at higher levels of organization. Usually high-ranking officer exchanges were negotiated for specifically named people. There were some exchanges based on numbers for random lower-ranking people, but these were limited.

Three other aspects were different from those normally seen in modern warfare. The first is that letters were permitted and sometimes even encouraged. Prisoners could buy or exchange for food and clothing, including any money sent by their families. The second was the use of 'Parole' by both sides. This would allow prisoners some freedom, in exchange for their promise not to resume the war. The last is that prisoners were encouraged to enlist in the army of the other side. Over the course of the war, as much as a quarter of each army had actually seen service on the other side.

American prisoners
George III of Great Britain had declared American forces traitors in 1775, which denied them prisoner of war status. However, British strategy in the early conflict included pursuit of a negotiated settlement and therefore officials declined to try and/or hang them, the usual procedure for treason, to avoid unnecessarily risking any public sympathy the British might have enjoyed in the Americas. The Continental Army capture of a British army at the Battle of Saratoga in 1777 resulted in thousands of British prisoners of war in the hands of the Americans. This had the effect of further dissuading British officials from hanging Colonial prisoners, despite the abandoned hopes of a settlement by this stage, as they feared reprisals on prisoners being held by the Americans. Neither policy, however, prevented the British from treating common American military members being held prisoner far more harshly than the standards of the day for POWs allowed. In actuality, a malicious British neglect resulted in starvation and disease slowly and torturously achieving the same results as hanging for many American prisoners of war, or disability and inhumane suffering for most others who were not officers or otherwise likely to be useful in prisoner exchanges.

The British forces held relatively few places in strength for long periods. American prisoners of war tended to be accumulated at these sites. New York City was a major site of occupation, where sugar houses were used to detain prisoners of war. Philadelphia in 1777 and later Charleston, South Carolina, were also important. Facilities at these places were limited. At times, the occupying army was actually larger than the total civilian population.

The British solution to this problem was to use obsolete, captured, or damaged ships as prisons. Conditions were appalling, and many more Americans died of neglect while imprisoned than were killed in battle. While the Continental Army named a commissary to supply them, the task was almost impossible. Elias Boudinot, as one of these commissaries, was competing with other agents seeking to gather supplies for George Washington's army at Valley Forge.

During the war, at least 16 hulks, including the infamous HMS Jersey, were placed by British authorities in the waters of Wallabout Bay off the shores of Brooklyn, New York as a place of incarceration for many thousands of American soldiers and sailors during about 1776–83. These prisoners of war were harassed and abused by guards who, with little success, offered release to those who agreed to serve in the British Navy. Over 10,000 American prisoners of war died from neglect. Their corpses were often tossed overboard, though sometimes they were buried in shallow graves along the eroding shoreline. Many of the remains became exposed or were washed up and recovered by local residents over the years and later interred nearby in the Prison Ship Martyrs' Monument at Fort Greene Park, once the scene of a portion of the Battle of Long Island.

Survivors of the British Prison Ships include the poet Philip Freneau, and Congressman Robert Brown.

Continental Army prisoners of war from Cherry Hill were held by Loyalists at Fort Niagara near Niagara Falls, New York and at Fort Chambly near Montreal.

British and German prisoners
During the American Revolutionary War, George Washington and his Continental Army put the laws of war into practice regarding prisoners of war unlike their opponents who did not. The British believed that Colonial American soldiers were traitors and not entitled to POW status and would treat them as unlawful combatants and subject them to execution on the battlefield if captured as what happened at the Battle at Drake's farm during the Forage War. The Americans took a different view. They believed that all captives should be taken prisoner. After winning the Battle of Trenton on Christmas Day 1776, Washington found himself left with hundreds of Hessian troops who had surrendered to the Americans. Washington ordered his troops to take the prisoners in and "treat them with humanity," which they did. "Let them have no reason to complain of our copying the brutal example of the British army," Washington said. Some British and Hessian prisoners of war were paroled to American farmers. Their labor made up for shortages caused by the number of men serving in the Continental Army. Usually their return was room and board, supplied by the contractor.
