Chief Logan, Tah-gah-jute, a Mingo chief named Logan and a native of Pennsylvania, moved to Ohio in 1770 and settled at the Pickaway Plains. Logan and his father, Shikellimus, had long supported friendships between Native Americans and white men, but in the spring of 1774 his tribesmen and family were murdered at Yellow Creek along the Ohio River. Once an advocate of peace, Logan then went on the warpath and raided frontier settlements, and these and similar raids along the Ohio frontier helped precipitate Lord Dunmore's War in October 1774. After the Shawnees and their allies were defeated at Point Pleasant, Virginia governor Lord Dunmore marched up the Hocking River to the Pickaway Plains and asked his interpreter, Colonel John Gibson, to assist in negotiations with Cornstalk and other Indian leaders, including Logan. Logan declined to attend the conference, but spoke to Gibson about his anger and betrayal. It was here under a large elm tree that Logan was said to have delivered his powerful speech on Indian-white relations, which Gibson delivered to Lord Dunmore at Camp Charlotte. Logan's lamentation was printed widely and appeared in newspapers in New York, Philadelphia, and Williamsburg in 1775. The speech is inscribed on the Chief Logan Monument, worded as it was related to President Thomas Jefferson. The elm, once considered one of the largest in the United States and sixty-five feet tall, died in 1964 after blight and storm damage, and through the efforts of the Ohio History Day Association this location was dedicated as Logan Elm Park. The Ohio Historical Society currently operates the Logan Elm State Memorial.
