There is a monument in Petersburg honoring a general who fought for the "enemy" (the British) during the Revolutionary War.
General William Phillips led a portion of the British army that marched from Canada into New York in 1777. He forced the surrender of Fort Ticonderoga, by careful placement of cannon on a hill where the Americans thought would be impossible to fortify.
General Phillips surrendered himself at Saratoga with the rest of Burgoyne's army, after that British invasion failed. He was imprisoned at Charlottesville and socialized with Thomas Jefferson before being exchanged in November 1779.
As an exchanged officer, he was entitled to resume his role in the British Army. Sir Henry Clinton in New York sent Phillips to command in Virginia in 1781. He superseded Benedict Arnold, who had captured Richmond and brought British forces back to their base in Hampton Roads before Phillips arrived.
General Phillips renewed the offensive, in order to disrupt the delivery of troops and supplies that were going south from Virginia to American forces in South Carolina. He captured Williamsburg and then Petersburg, but became seriously ill there from perhaps typhus or malaria. The general died in Petersburg in the home of the Bolling family on May 13, 1781.
General Phillips was buried in the cemetery of Blandford Church. The burial was secret and the grave unmarked, so American rebels could not desecrate the body or even dig it up for display in an undignified manner. Benedict Arnold resumed command of the British forces that had invaded Virginia, until Lord Cornwallis arrived.1
In 1914, 133 years later, a chapter of the Daughters of the American Revolution installed a monument at the Blandford Church graveyard. The stone was inscribed with:2
The first monument to commemorate a military event in the United States is located in Massachusetts. That monument was erected at the Lexington Battle Green in 1799, where the "shots heard 'round the world" were fired in 1775 to trigger the military phase of the American Revolution.
The second oldest war memorial is also associated with the Revolutionary War. It is a marker, erected in 1815, thought to document the graves of four American officers and Col. Patrick Ferguson, the British officer in charge of the Tory forces defeated at Kings Mountain on October 7, 1780. Because the inscription is so eroded, a second monument with the same words was erected next to it in 1914.3
