PHILADELPHIA (AP) — A sword belonging to a close friend of George Washington
 who was a battlefield hero has been given to Philadelphia's new Museum of the American Revolution.
The St. Andrew's Society of Philadelphia presented Gen. Hugh Mercer's sword on Thursday to the museum, which opens April 19 — the anniversary of the war's opening battles in 1775.
The society, named in honor of Scotland's patron saint, was founded in 1747. Mercer was a member.
Mercer was mortally wounded at the Battle of Princeton on Jan. 4, 1777. He died in the
 Thomas Clarke House at Princeton, New Jersey, nine days after the battle ended in
 victory for the Continental Army.
His body was laid out at Philadelphia's City Tavern the day before his internment
 so mourners could pay their final respects.
