Upon reading the posts at SDG, it is evident that Confederate Cavalry officer, Basil Duke, is a favourite of many. A veteran of the Battle of Shiloh, who afterwards became involved with the progress of Shiloh Memorial Park (which eventually became Shiloh NMP), and who was often invited as Speaker at Dedication events... But, unknown to most, is that prior to the Civil War, Basil Duke was a base ball player.
Born in Kentucky in 1838, Basil Duke took his Law degree earned at Transylvania College west and settled in St. Louis, where he joined his cousin's law firm and became involved in militia activities and base ball. A member of the Cyclones in time for the 1860 season, he played against other St. Louis clubs named Morning Stars, Unions, Tigers, Excelsiors, Independents and Empires, on fields around the city, recorded as Lafayette Park, Laclede Ground, Commercial Ground, Gamble Lawn Ground, and "the field immediately west of the Fair Grounds." In 1861, Basil Duke missed the March opening of the Season (away with "other activities") and as far as is known, never played for the Cyclones again. During 1861, the young man returned to Kentucky and signed on with another cousin: John Hunt Morgan.
Base ball (spelled as two words) continued in St. Louis during the War (but often involved the club's "second nine," with their First Nine being otherwise engaged.)
