Pompano's first mayor, John Mizell, was a Civil War veteran having served as a Captain in Company F of the 7th Florida Volunteers. His unit was part of the Confederate Army of Tennessee, fighting at such battles as Chickamauga and Atlanta.

Florida Volunteer Infantry regiments were constantly being consolidated with other Florida regiments. In April, 1864, the 7th Florida Infantry regiment was consolidated into the 1st Florida and the resulting unit was known as the First Florida Consolidated Infantry. The consolidations were due to the loss of a large number of their men to both combat and sickness, and to make an effective fighting force the regiments had to be combined.
