the "Columbia Massacre," or the "Battle of a Thousand Slain". It remains the greatest defeat of a US Army by Native Americans in history, with about 623 American soldiers killed in action and about 50 Native Americans killed. The wounded were many, including St. Clair and Capt. Robert Benham. Although an investigation exonerated him, St. Clair resigned his army commission in March 1792 at the request of President Washington, but he continued to serve as Governor of the Northwest Territory. A Federalist, St. Clair hoped to see two states made of the Ohio Territory in order to increase Federalist power in Congress. However, he was opposed by Ohio Democratic-Republicans for what were perceived as his partisanship, high-handedness, and arrogance in office. In 1802, St. Clair remarked the U.S. Congress had no power to interfere in the affairs of those in the Ohio Territory. He also stated the people of the territory "are no more bound by an act of Congress than we would be bound by an edict of the first consul of France." This led President Thomas Jefferson to remove him from office as territorial governor. He thus played no part in the organizing of the state of Ohio in 1803. The first Ohio Constitution provided for a weak governor and a strong legislature, in part as a reaction to St. Clair's method of governance. Family life St. Clair met Phoebe Bayard, a member of one of the most prominent families in Boston, and they were married in 1760. Miss Bayard's mother's maiden name was Bowdoin and she was the sister of James Bowdoin, colonial governor of Massachusetts. His eldest daughter was Louisa St. Clair Robb, a mounted messenger and scout, and known as a beautiful huntress. Like many of his Revolutionary era peers, St. Clair suffered from gout as noted in correspondence with John Adams. Death In retirement St. Clair lived with his daughter, Louisa St. Clair Robb, and her family on the ridge between Ligonier and Greensburg. Arthur St. Clair died in poverty in Greensburg, Pennsylvania, on August 31, 1818, at the age of 81. His remains are buried under a Masonic monument in St. Clair Park in downtown Greensburg. St. Clair had been a petitioner for a Charter for Nova Caesarea Lodge #10 in Cincinnati, Ohio, in 1791. This Lodge exists today, as Nova Caesarea Harmony #2. His wife Phoebe died shortly after and is buried
