In the Indian Massacre of 1622, Native Americans destroyed Henrico City and the ironworks to try to drive away the English. These were not rebuilt. The colony did not gain a college until 1693, when the College of William and Mary was awarded a royal charter in the capital. In 1634, the King of England directed the formation of eight shires (or counties) in the colony of Virginia. One of these was Henrico County, which incorporated a large area on both sides of the James River. On 25 May 1749, the Virginia House of Burgesses separated Chesterfield from Henrico County and created the new county. The first county seat was established at Chesterfield Court House. It has continued as county seat except for 1870–1876, during Reconstruction, when the county government was located at Manchester. The latter community has been subsumed by South Richmond. The legislature named the county for the former British Secretary of State, Philip Stanhope, 4th Earl of Chesterfield. Lord Chesterfield was famous for his "good manners and writings". One of his most frequently used sayings implies avoiding rudeness; "An injury is much sooner forgotten than an insult." Many years later, Chesterfield Cigarettes were named after this county. In 1939 during the Great Depression, the Virginia State Police moved their offices from downtown Richmond to a seven-room farmhouse located on of land 3½ miles west on route 60. This structure served as administrative headquarters and barracks. The State Police have since built a new administrative headquarters and an academy here. Prior to the American Revolutionary War, a thriving port town named Warwick was located at the northwestern confluence of Falling Creek and the James River. It was destroyed during that war, and not rebuilt. (Near the present-day DuPont facility at Ampthill, the site is not open to the public.) Another early port town was Port Walthall on the north shore of the Appomattox River, near the current Point-of-Rocks Park. Coal mining in the Midlothian area of Chesterfield County began in the 18th century. Around 1701, French Huguenot settlers to the area discovered coal. In a 1709 diary entry William Byrd II, the wealthy planter who had purchased of land in the area, noted that "the coaler found the coal mine very good and sufficient to furnish several generations." Commercially mined beginning in the 1730s, the coal fueled the production of cannon at Westham (near the present Huguenot Memorial Bridge) during the American Revolutionary War.
