On Sept. 19, 1862, a Confederate force occupied Owensboro. USA troops at the old Fairgrounds refused a demand for surrender, and a skirmish followed. A Union soldier swam the Ohio River to summon help from the Indiana Legion. The CSA retired to this place, where Home Guards from Indiana crossed the river and attacked the next day. The CSA retreated with 36 killed and 70 wounded, while the USA lost 3 killed and 35 wounded.
