The USSC's Department of the Gulf was established in New Orleans in 1862. This city became the Department's base for operations for supply distribution and relief efforts in support of soldiers and sailors in military operations along the Gulf Coast, from Texas to Florida, and into the interior of Louisiana. Its agents accompanied troops during the siege of Port Hudson, 1863, and the Red River campaign in 1864, and sailed with hospital ships carrying sick and wounded soldiers up the Mississippi River. In New Orleans, the USSC established a strong presence by distributing numerous supplies to hospitals, regiments and naval ships. Its Soldiers' Home provided food and shelter to soldiers in transit, becoming the hub of special relief services to soldiers and their families, including assistance in filing pension and other claims. The Department of the Gulf Archives, 1862-1866, comprise the records of its main office, notably the correspondence of George A. Blake and Edward A. Crane, who directed Department activities; its Special Relief Department, as seen in correspondence, record books documenting services at the Soldiers Homes in New Orleans and Brashear City, Louisiana, and back pay and bounty books recording claim assistance. Supply Department records document the extensive distribution of supplies in New Orleans and elsewhere, and to relief agents for use in the field. Other materials include receipts, cancelled checks and miscellaneous documents.
