He served as a lieutenant in Company F, 11th Florida Infantry but resigned in June of 1864 due to illness. In the spring of 1863, however, he was acting commander of the unit which was then stationed at Campbellton in Jackson County, Florida (after a transfer from Company C of the same regiment). You might recall that Company F was Captain John Tanner's unit, which is mentioned extensively in Gov. Shorter's correspondence in 1863 due to its alleged involvement in supplying weapons for the deserter gang then active on the tributaries of the upper Chipola River in Henry County.
According to the regimental reports for the 11th Florida, both Companies C and F were identified as "Captain Curry's Independent Infantry" prior to being incorporated into the regiment. Captain E.A. Curry, I assume a relative, headed Company C. This unit had initially been stationed at Camp Boynton, which was on the Choctawhatchee River in Florida. In her application for a pension, his widow later noted that Whitmill Curry served for 12 months in an "independent company."
He died on March 10, 1898, at the age of 72. At that time he was a resident of the Izagora community in Holmes county, Florida. His widow filed for and received a Florida pension (A11170). His widow, Martha Lassiter Curry, later lived in Black, Alabama and I think was probably related to the Lassiter family of Dale County.
I have some information on his civilian life if you need any of that.
