The 1st Florida Union Cavalry was formed in October 1863 from men primarily from south Alabama and northwest Florida. The regiment was stationed at Fort Barrancas in Pensacola, FL; served along the upper Gulf Coast with other Union regiments and participated in a number of engagements from Marianna, FL to Mobile, AL. The book explores the history of the area before and during the early years of the war and the history of the regiment including information on any engagements the 1st Florida Union Cavalry participated in (locations - then and now, regimental opponents, victors, list of men known to participate and summaries of the engagements). Also includes data on the individual men who served in the regiment (military data-Union and Confederate, 1860 census locations, birth and death, burial, and pension index information). Together the information provides a glimpse of this area of the deep South during the Civil War and is an excellent genealogy reference for descendants.
