Question: Peggy is a 1970 historical novel by Lois Duncan, It is a semi-fictionalized account of the life of which second wife of General Benedict Arnold, a prominent figure in Philadelphia after the American Revolutionary War?
Context: USS "Philadelphia" is a gunboat (referred to in contemporary documents as a gundalow or gondola) of the Continental Navy.  Manned by Continental Army soldiers, she was part of a fleet under the command of General Benedict Arnold that fought the 11 October 1776 Battle of Valcour Island against a larger Royal Navy fleet on Lake Champlain.  Although many of the American boats in the battle were damaged in the battle, "Philadelphia" was one of the few actually sunk that day.  On the days following the main battle, most of the other boats in the American fleet were sunk, burned, or captured.  She is one of a few such vessels used during the American Revolutionary War to be raised. The Battle of Groton Heights (also known as the Battle of Fort Griswold, and occasionally called the Fort Griswold massacre) was a battle of the American Revolutionary War fought on September 6, 1781, between a small Connecticut militia force led by Lieutenant Colonel William Ledyard and the more numerous British forces led by Brigadier General Benedict Arnold and Lieutenant Colonel Edmund Eyre. Peggy is a 1970 historical novel by Lois Duncan.  It is a semi-fictionalized account of the life of Peggy Shippen, the second wife of General Benedict Arnold, a prominent figure in Philadelphia after the American Revolutionary War. Benedict Arnold: A Question of Honor is a 2003 American television film directed by Mikael Salomon and starring Aidan Quinn, Kelsey Grammer, Flora Montgomery and John Light.  It portrays the career of Benedict Arnold in the American Revolutionary War and his dramatic switch in 1780 from fighting for American Independence to being a Loyalist trying to preserve British rule in America.  Arnold's relationships with his wife Peggy Shippen and the British officer John Andre are focused on.  The friction between Arnold and General Horatio Gates, portrayed near the beginning of the film (for example, in one scene when Arnold derisively refers to him as "Granny Gates"), was historically accurate.  The movie points out that, before his treason, Arnold was considered a patriot and a hero.  A letter from General Washington is read at the beginning where he enthusiastically recommends Arnold for promotion saying that there is no general in the army more deserving and even comparing him to Hannibal.  The movie briefly documents Arnold's final years of exile in England in which he laments his treasonous acts, realizing that he is despised and that people compare him with Judas and Lucifer. "To the Inhabitants of America" is an open letter written by former Continental Army Major General Benedict Arnold not long after his defection to the British side in the American Revolutionary War.  The letter, dated October 7, 1780, was published in New York City on October 11.  In it, Arnold explains his justification for his actions. The Boot Monument is an American Revolutionary War memorial located in Saratoga National Historical Park, New York.  It commemorates Major General Benedict Arnold's service at the Battles of Saratoga in the Continental Army, but contrives not to name him. Margaret "Peggy" Shippen (July 11, 1760 – August 24, 1804) was the second wife of General Benedict Arnold.  Shippen garnered notoriety for being the highest-paid spy in the American Revolution. Joshua Hett Smith House (demolished), also known as Treason House, was a historic house in West Haverstraw, New York.  It stood on a hill overlooking the King's Ferry at Stony Point, an important crossing of the Hudson River.  During the American Revolutionary War, General Benedict Arnold met at the house with British Major John André, while plotting to surrender the fort at West Point.  Later, the house had a brief tenure as headquarters for General George Washington. The Arnold family is an American political and military family with ties to New England, Georgia and Ohio.  The descendents of American Revolutionary War general Benedict Arnold in Great Britain, while not particularly politically active, also achieved notable success in the 19th century. Ethan Allen (January 21, 1738 [O.S. January 10, 1737] – February 12, 1789) was a farmer, businessman, land speculator, philosopher, writer, lay theologian, and American Revolutionary War patriot, hero, and politician.  He is best known as one of the founders of the U.S. state of Vermont, and for the capture of Fort Ticonderoga early in the American Revolutionary War along with Benedict Arnold.  He was the brother of Ira Allen and the father of Frances Allen.
