Question: Margaret "Peggy" Shippen, was the second wife of which general during the American Revolutionary War, who fought for the American Continental Army, and later defected to the British Army?

<P0-S0>  While a general on the American side, he obtained command of the fortifications at West Point, New York (which after 1802 would become the site of the U.S. Military Academy), overlooking the cliffs at the Hudson River (upriver from British-occupied New York City), and planned to surrender them to British forces. <P0-S1> Benedict Arnold (January 14, 1741 [O.S. January 3, 1740] June 14, 1801) was a general during the American Revolutionary War, who fought for the American Continental Army, and later defected to the British Army. <P0-S2>  This plan was exposed in September 1780. <P0-S3>  He was commissioned into the British Army as a brigadier general. <SEP> <P1-S0> The 1st Virginia State Regiment was a regiment of Virginia Militia that fought during the American Revolutionary War. <P1-S1>  The regiment was authorized by the General Assembly of the Commonwealth of Virginia in December 1776 as a force of regular troops for the Commonwealth's defense. <P1-S2>  In 1777, Virginia had difficulty meeting its quota for the regular line of the Continental Army. <P1-S3>  As a result, in July 1777 under the command of Colonel George Gibson, the regiment began a march North to temporarily join the Continental Army in the Philadelphia Campaign. <P1-S4>  In January 1778, the Virginia General Assembly passed an act directing that the 1st Virginia State Regiment "now in Continental service, be continued in said service instead of the Ninth Virginia Regiment, made prisoners by the enemy in the Battle of Germantown." <P1-S5>  The regiment camped at Valley Forge in the winter of 1777-78 and at Middlebrook in the winter of 1778-79 and participated in the Battle of Monmouth. <P1-S6>  The regiment remained in the service of the Continental Army until late 1779 when redeployed Virginia. <P1-S7>  Unlike the standard division of eight found in the regular line regiments of the Continental Army, the 1st Virginia State Regiment consisted of ten companies including one of light infantry. <SEP> <P2-S0>  Shippen garnered notoriety for being the highest-paid spy in the American Revolution. <P2-S1> Margaret "Peggy" Shippen (July 11, 1760 – August 24, 1804) was the second wife of General Benedict Arnold. <SEP> <P3-S0> Nicholas Haussegger (1729 – July 1786) was born in Switzerland and fought in the British army during the French and Indian War. <P3-S1>  After the war he became a leader in the Pennsylvania German community. <P3-S2>  At the beginning of the American Revolutionary War he joined the 4th Pennsylvania Battalion as a field officer. <P3-S3>  He was placed in command of the German Battalion, a unit of ethnic Germans from Pennsylvania and Maryland. <P3-S4>  He led his battalion effectively at Trenton in late December 1776. <P3-S5>  A week later, he was captured at Assunpink Creek under questionable circumstances. <P3-S6>  He apparently defected to the British and George Washington had him watched after he was sent home on parole. <P3-S7>  He was stricken from the Continental Army in March 1777. <P3-S8>  Evidence suggests that he was in contact with the British during the war. <P3-S9>  In 1782 he was declared a traitor and his property forfeited. <P3-S10>  He died in July 1786.
